Answer:
T=11.50(x +y) + 278Step-by-step explanation:
in this problem we are looking at an alternative expression to the given expression for the total earning which is
Given data
T=11.50x + 125 + 11.50y + 153
let us collect like terms we have
T=11.50x + 11.50y + 153+ 125
T=11.50x + 11.50y +278
we can factor out 11.5 since it is common
T=11.50(x +y) + 278
The alternative expression the girls could use is
T=11.50(x +y) + 278

Mrs. Owens bought two candle holders for her dining room table. She paid with a $100 bill and received $32.16 in change. If sales tax is charged at a rate of 6%, what was
the price for one candle holder before taxes?
Drag and drop an answer choice into each empty box below.
$32.00 $32.16 $33.92 $63.76
The price of one candle holder before taxes was
Answer:
$32.00
Step-by-step explanation:
100-36.12 = 67.84 - That's how much she paid for 2 after tax.
So let's eliminate the wrong answers:
63.76*2 is way over 100 so it's not that
33.92*2 is 67.84, but the question asks before taxes so it's not that
32.16*2 is 64.32, but there is tax so we must multiply it by 1.06. 64.32*1.06 is 68.18
32*2 is 64. 64*1.06 is 67.84. There for the correct answer is $32.00

Which of the following expressions is modeled on the number line?
The first arrow goes from 0 to 3, which is 3 units.
The second arrow goes from 3 to 6, which is another 3 units.
The total units is 3 + 3 = 6
This means you have 2 different sets of 3, which can be modeled by 2 x 3.
The second choice is correct.
Mr. Donley drove 504 km in each direction on a vacation
trip. The average rate going was 14 km/h faster than the
rate returning. The total time for the entire trip was 21
hours. Find the average rate for each direction.
Answer:
Data that we know:
He drove 504km in each direction.
Going, the average speed was 14km/h more than returning.
The total trip lasted 21 hours.
Ok, to solve this first:
Let's define the variables:
Sg = Average speed when going.
Sr = Average speed when returning.
Then we can write one of our relationships as:
Sg = Sr + 14km/h.
Now, you can recall the relation:
Time = Distance/speed.
Then we can write the equation that represents the total time of the travel as:
504km/Sg + 504km/Sr = 21h
Now we can replace the Sg by Sr + 14km/h, and get:
504km/(Sr + 14km/h) + 504km/Sr = 21h.
Now we must multiplacate by each denominator, in order to remove them:
504km*Sr + 504km*(Sr + 14km/h) = 21h*Sr*(Sr + 14km/h)
Sr*1008km + 7056km^2/h = 21h*Sr^2 + 294km*Sr
Now we can write a cuadratic equation, where i will ignore the units so it is easier to read, as:
21*Sr^2 -714*Sr - 7056 = 0
The solutions are given by the Bhaskara formula:
[tex]Sr = \frac{714 +- \sqrt{714^2 - 4*21*(-7056)} }{2*21} = \frac{714 +- 1050}{42}[/tex]
We have two solutions, one negative and one positive, and because Sr represents an average speed, it must be a positive number, then we choose the positive solution:
Sr = (714 + 1050)/42 km/h = 42km/h
Now we have the average speed for the returning, with this we can find Sg.
Sg = Sr + 14km/h = 42km/h + 14km/h = 56km/h.
Dora, the school lunch manager, says that it takes 225 oranges to make 5 gallons of orange juice how many oranges does Dora need to make one gallon?
Answer:
45
Step-by-step explanation:
Since
5 : 225 = 1 : X
Then we know
225/5 = X/1
Multiplying both sides by 1 cancels on the right
1 × (225/5) = (X/1) × 1
1 × (225/5) = X
Then solving for X
X = 1 × (225/5)
X = 45
Therefore
5 : 225 = 1 : 45
Answer:45
Step-by-step explanation:well all you do is divide 5 from 225

The table shows the outputs, y, for different inputs, x:
Input 2 4 6 8
Output
(y)
1 2 3 4
Part A: Do the data in this table represent a function? Justify your answer. (3 points)
Part B: Compare the data in the table with the relation f(x) = 3x - 10. Which relation has a greater value when x = 8? (2 points)
Part C: Using the relation in Part B, what is the value of x if f(x) = 80? (5 points)
(10 points)
Answer:
A: The data does represent a function because there are no repeating x values. a function can have repeating y values but cannot have repeating x values. Also, there is one value of y for every value of x.
B: f(x)=1/2x
f(x)= 3x-10
f(8)=1/2(8) ----> 4
f(8)=3(8)-10 ----> 14
f(x)=3x-10 has a greater value when x=8
C: f(x)=1/2x
f(x) = 80
80=1/2x
80*2=x
x=160
Step-by-step explanation:
The data in the table is a function. The relation has f(x) = 3x - 10 has greater value when x = 8. And the value of x is 30 when f(x) = 80.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Part A :
The table has the data values,
x : 2 4 6 8
y : 1 2 3 4
The given data represents a function, because elements in the domain (2, 4, 6 and 8) has only one image in the Range (1, 2, 3 and 4).
Part B :
f(x) = 3x - 10
x = 2, then f(x) = y = -4
x = 4, then f(x) = y = 2
x = 6, then f(x) = y = 8
x = 8, then f(x) = y = 14
The relation f(x) = 3x - 10 has the greater value when x = 8.
Part C :
f(x) = 80
3x - 10 = 80
3x = 80 + 10
3x = 90
x = 90 / 3
x = 30
Hence the relation in the table is a function. The second relation f(x) = 3x - 10 has the greater value when x = 10 after computing the values of both the relations.

Enter the value for x that makes the given equation true.
20x-5(6x+4)=4x-6
(Please show work so I can be able to understand it how this works)
Answer:
x = -1
Step-by-step explanation:
20x - 5(6x + 4) = 4x - 6
20x - 30x - 20 = 4x - 6
-10x - 20 = 4x - 6
-10x - 4x = -6 + 20
-14x = 14

Question: p=2w+2l for l
A- l=p-w
B- l=w-p
C- l=2w-p/2
D- l=p-2w/2
Answer: Choice D
Step-by-step explanation:
p=2w+2l Subtract 2w from both sides
p - 2w = 2w - 2w +2l 2w-2w = 0 cancels
p- 2w = 2l . Divide both sides by 2 2/2 =1 cancels leaving l isolated
p - 2w/2 = l
Reverse
l = p-2w/2

6х + 17 = -7
justify each step
Answer:
x = -4
Step-by-step explanation:
Subtract 17 on both sides to get 6x = -24 then divide 6 to both sides to get your answer of x = -4
First, you need to get 6x by itself. So you would subtract 17 from both sides. After that you should have 6x= -24.Then you need to get x by itself. You divide 6 from both sides. The answer is x= -4.

Two shops, Lidal and Oldi, sell the same brand of toilet rolls but with different package sizes. Calculate the price per 36 rolls for each shop. Write which shop is the best value for money in the comment box. lidals deal is 9 £3.51 oldi deal is 4 £1.52
Answer: Oldi gives the best value of money.
Step-by-step explanation:
Lidal's deal : 9 rolls for £3.51
Oldi's deal : 4 rolls for £1.52
Cost per roll = [tex]\dfrac{\text{total cost}}{\text{Number of rolls}}[/tex]
So,
For Lidal, Cost per roll = [tex]\pounds\dfrac{3.51}{9}=\pounds0.39[/tex]
For Oldi', Cost per roll = [tex]\pounds\dfrac{1.52}{4}=\pounds0.38[/tex]
Clearly, [tex]\pounds 0.39> \pounds 0.38[/tex]
Hence, Oldi gives the best value of money.
