Given that you have 2 parallel lines cut by a transversal, what is the measure of angle 2?
Step-by-step explanation:
angle 2 = 2x + 10 deg (corresponding angles) or 180 - 4x + 46 deg (angles on a straight line are supplementary)
therefore,
2x + 10 = 226 - 4x
6x = 216
x = 36
hence,
angle 2 = 2(36) + 10 = 82deg

At Grocery Mart, strawberries cost $2.99 for 2 lb., and at Baldwin Hills Market strawberries are $3.99 for 3 lb.
What is the unit price of strawberries at each grocery store? If necessary, round to the nearest penny.
Grocery Mart:
$_________
Answer:
Unit Price at Grocery Mart = $1.50
Unit Price at Baldwin Hills = $1.33
Step-by-step explanation:
Unit price in this case will be the price divided by number of pounds
Let u1 be the unit price of Grocery Mart and u2 be the unit price at Baldwin Hills
Given
[tex]s_1 = 2.99\\w_1 = 2\\s_2 = 3.99\\w_2 = 3[/tex]
The unit price for Grocery Mart is:
[tex]u_1 = \frac{s_1}{w_1}\\= \frac{2.99}{2}\\= 1.495[/tex]
Rounding off to nearest penny
u1 = $1.50 per lbs
Unit price for Baldwin Hills is:
[tex]u_2 = \frac{s_2}{w_2}\\=\frac{3.99}{3}\\=1.33[/tex]
u2 = $1.33 per lbs
Hence,
Unit Price at Grocery Mart = $1.50
Unit Price at Baldwin Hills = $1.33

Jack bought 5 pairs of socks for $12.50. At this rate, how much would 12 pairs of socks cost?
Answer: $30
Step-by-step explanation:
5 pairs of socks cost 12.50 you divide 12.50 by 5 and you how much each pair of socks cost which is 2.5 which is 2.50 each pair of socks is 2.50 so now you multiply 2.50 by 12 and you get $30
If sale tax is 9% and you want to buy three t-shirts that cost $17.00 each, how much tax will you pay?
Answer:

Nerissa paid a total of $8 for 4 packs of pencils she purchased from the convenience store. Let p represent the cost of one pack of pencils.
Which equation shows an equality between two different ways of expressing the cost for all the pencils?
A. 8 = 4p
B. 8 = 4/p
C. 8 = 4 + p
D. 8 = 4 – p
==================================================
Explanation:
p is a placeholder for a number. Think of it like a box where a number goes inside.
In this case, p is the price of one pack of pencils.
We can use a proportion to help set up an equation
(4 packs)/(8 dollars) = (1 pack)/(p dollars)
4p = 8*1 ... cross multiply
4p = 8
8 = 4p which points to choice A as the answer.
---------------------------
Alternative method:
4 packs = 8 dollars
1 pack = p dollars
Multiply both sides of the second equation by 4 and you'll get
4 packs = 4p dollars
Then replace the "4 packs" on the left hand side with "8 dollars"
8 dollars = 4p dollars
that turns into
8 = 4p
--------------------------
Yet another method:
We know it's $8 for 4 packs. This must mean it is 8/4 = 2 dollars per pack.
If p is the cost of one pack, then p = 2.
Now plug p = 2 into each of the four answer choices. You should find that only 8 = 4p results in a true equation.
Choice B is false because 8 = 4/p turns into 8 = 4/2 and that becomes 8 = 2, which is a false equation. Choices C and D are similar stories.
Answer:
The answer is A
Step-by-step explanation:
If C=24, what values of A and B complete Ax+By=C for each graph? Write the standard form for each equation.
For the graph in part a, the value for A is =
and the value for B is =
Answer:
Step-by-step explanation:
For graph (a),
Let the equation of the line is,
Ax + By = C
For the line passing through (4, 0) and C = 24,
4A + B(0) = 24
4A = 24
A = 6
For a point (0, -3) lying on this line,
A(0) + B(-3) = 24
-3B = 24
B = -8
Therefore, equation of the line will be,
6A - 8B = 24
3A - 4B = 12
b). If the equation of the given line is,
Ax + By = 24
For a point (3, 0) lying on the line,
3A + B(0) = 24
A = 8
For a point (0, 2) lying on the line,
A(0) + 2B = 24
2B = 24
B = 12
Therefore, equation of the given line will be,
8A + 12B = 24
2A + 3B = 6
The thickness of a block is approximately 2 centimeters. How many blocks are in a stack that is 1,000 millimeters high? ( 1 cm = 10 mm ) Use proportions. Help please with explanation thank you!!
Answer:
50 blocks
Step-by-step explanation:
First of all, you need to label you're proportions, which can be mm/blocks.
Then, for 1 block, it is 20 mm because the block is 2 cm, which is equal to 20 mm. So for you're proportion, it is 20 mm/1 block.
Finally, you need to find the total amount of blocks that equals 1000 mm. So you can multiply the 20 mm by 50 to get the 1000 mm. What you do at the top, you do at the bottom, so you also have to do 1 block by 50 to get 50 blocks
So for you're final answer/proportion, it is mm/blocks = 20/1 = 1000/50 and you're final answer is 50 blocks

b
Reflection over the x-axis
c
Translation 5 units left and 2 units down
d
Translation 10 units left and 4 units down
Answer: You're answer to you question would be D
Step-by-step explanation:
The correct description of the transformation translation 10 units left and 4 units down. The correct option is D.
What is transformation?The transformation can be defined as the introduction of a new set of mathematical coordinates that are declared to be different functions of the original coordinates.
Given the per-image and image of different points. Now, if we look at the coordinates of the A and A', then it can be observed that if 10 units is deducted from the x-coordinate of A, then the x-coordinate of A' will be the result.
Similarly, if 4 units is deducted from the y-coordinate of A, then the y-coordinate of A' will be the result.
Further, it is known that reducing n units from x-coordinate means that the point is shifted left by n units. Also, if p units are deducted form the y-coordinate then the point is shifted p units down.
Hence, the correct description of the transformation translation 10 units left and 4 units down.

The school nurse told Sarah she was 1.4 meters tall. When she got home, Sara measured her height herself. Her measurement included a digit in the hundredths place. That digit had a value that is the value of the digit in the tenths place. How tall did Sara measure herself to be?
Answer:
1.44 meters
Step-by-step explanation:
Given that:
As per the nurse, height of Sarah = 1.4 meters
Let us have a look at the number and let us analyze each digit.
Here is only one digit after the decimal place which is the tenths place.
It is given that Sarah measured the height herself.
And also added a digit at the Hundredth place i.e. a digit after 4 will be added.
1.4_ --- In place of _ , a digit will be added.
As per the question statement, Digit at the Hundredth place will be equal to the digit at the Tenth's place.
Therefore, the height measured by Sarah herself will be equal to 1.44 meters.
The graph represents the speed at which Pete’s marble travels.
The speed of Stephano’s marble is represented by the equation f = 2.25s, where f is the distance in feet and s is the time in seconds.
Whose marble will reach the 6-foot mark sooner?
Answer:
B
Step-by-step explanation:
Here, we simply want to know who will reach the 6-foot mark sooner
Mathematically, we need to get the slope from the graph
Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds
So what this mean is that, in 4 seconds, the 6 ft mark will be reached
This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs
Now compare this with what Stephano has, which is 2.25 ft/ s
we can see that stephano is traveling at a better speed and will reach the 6 ft mark first
So the correct option is B

hector and alex traded video games. alex gave hector one fourth of his video games in exchange for 6 video games. then he sold 3 video games and gave 2 video games to gis brother. alex enbed up with 16 video games. how many video games did alex have when he started?
Answer:
20 games
Step-by-step explanation:
Lets work backwards; *Adding what he gave away or lost*
-Alex started with 16 video games
-Add the games gave to his brother (+2)
-Add the games he sold (+3)
-The number is 3/4 of his games
-Subtract the games he traded with hector (-1/4)
Equation: 16+2+3-6= 3/4 X (variable) *You can choose other than X*
21-6 = 15
15 = 3/4
Take the reciprical of 3/4 which is 4/3 and multiply it by both sides
4/3 x 15 = 3/4 x 4/3
4/3 X 15 = 20!
ALEX STARTED WITH 20 GAMES!

Harry buys a TV priced at £1200 plus 20% VAT. He pays £300 deposit and the balance in ten equal monthly payments. Calculate each monthly payment. please explain fully in parts.
Answer:
114 monthly payment
Step-by-step explanation:
1200 + 20%= 1440 (20% of 1200 equals 240)
the VAT has to be added to the purchase price.
1440 is the total price he had to pay for the tv.
he pays 300 down. 1440-300 = 1140
1140 is the remaining balance he had to pay over the next 10 month.
1140 ÷ 10 = 114
divide 1140 by 10 payments and you receive you monthly payment amount. 114
