Answer:
-55
Step-by-step explanation:
7x-6y=2
-2x-y=3
by substitution method
y=3+2x
7x-6(3+2x)=2
7x-18-12x=2
-5x=20
x=-4
-2(-4)-y=3
8-y=3
-y=3-8
y=5
therefore the value of x=4 and that of y=5
5x-7y=5(-4)-7(5)
=-20-35
=-55

What is the value of x? Enter your answer in the box.
Answer:
x = 9
Step-by-step explanation:
Similar Triangles
We are given a shape where two similar triangles are given. The similarity theorem states that the side lengths of the triangles must be proportional in the same scale factor.
The total length of the left side is 72+9 = 81 cm
The smaller length of the left side is 9 cm
The proportion is 81/9 = 9. This is the scale factor.
The total length of the right side is 3x - 20 + 56 = 3x + 36
The smaller length of the right side is 3x-20
The proportion must be equal to 9:
[tex]\displaystyle \frac{3x+36}{3x-20}=9[/tex]
Multiplying by 3x-20:
3x+36=9(3x-20)
Operating
3x+36=27x-180
Rearranging:
24x = 216
Dividing by 24:
x = 9

Step-by-step explanation:
At 5:00 am, the temperature was -9°F, and at
9:00 am, it was 6'F. Which temperature is
farther from zero?
Answer:
-9°F
Step-by-step explanation:
If we have a horizontal line in which the zero is in the middle, the positive numbers are on the right and the negative numbers are on the right, we would see that -9°F is further than 6°F. Even though -9°F is a smaller temperature, it is still further away from the zero.

Margo places 6 pennies and 4 nickels in a jar. For the experiment, she selects a penny, replaces it, and selects another penny. If Margo repeats the experiment 100 times, how many times can she expect to select two pennies?
Answer: She is expected to select 2 pennies 36 times.
Step-by-step explanation:
In jar , we have
6 pennies and 4 nickels
Total coins = 10
The probability of getting two pennies ( with replacement) =
[tex]\dfrac{\text{Number if ways to get 2 pennies}}{\text{Total ways to select 2 coins}}\\\\=\dfrac{6\times6}{10\times10} \ \ [\text{independent events]}\\\\=\dfrac{36}{100}[/tex]
If Margo repeats the experiment 100 times, then expected number of times to select two pennies = [tex]\dfrac{36}{100}\times100=36[/tex]
She is expected to select 2 pennies 36 times.
We will see that Margo can expect to randomly select two pennies 36 times.
Probability of selecting two pennies at random.
The probability of selecting a penny at random is equal to the quotient between the number of pennies in the jar and the total number of coins in the jar, this is:
p = 6/10
And doing that two times, needs that probability two times, so the probability of selecting two pennies is:
p = (6/10)*(6/10) = 36/100
How many times she can expect to select 2 pennies in 100 attempts?Here we just need to multiply the above probability by 100, we will get:
(36/100)*100 = 36
So she can expect to get two pennies 36 times.

If tommy rode his bike 4.3 miles a day, 3 days a week for 5 years delivering news papers and he dropped 22.7 newspapers every 1/4 mile. How many newspapers did tommy drop?
Answer:
277 848 newspapers.
Step-by-step explanation:
Find out how much newspaper he drops for 4.3 miles.
1/4 = 0.25
4.3 miles ÷ 0.25 = 17.2
= 17
17 x 22.7 = 385.9
(Newspapers be dropped a day)
1 week of dropping newspapers = 385.9 x 3 = 1157.7
1 month of dropping newspapers = 1157.7 x 4 =
4630.8
1 year = 12 months
5 years = 12 x 5 = 60 months.
5 years/60 months of dropping newspapers = 4630.8 x 60 = 277 848
Tommy dropped 277 848 newspapers.

Answer:
x = 3
Step-by-step explanation:
3 ( x + 3 ) = 18
( 3 ) ( x ) + ( 3 ) ( 3 ) = 18
3x + 9 = 18
3x + 9 − 9 = 18 − 9
3x = 9
3x/3 = 9/3
x=3

Why do you think inequalities can have multiple solutions?
Answer:
Most of the time, an inequality has more than one or even infinity solutions. For example the inequality: x>3 . The solutions of this inequality are "all numbers strictly greater than 3".The inequality has an infinite amount of solutions.

If the sales tax rate is 5% in California, then how much would you pay in Los Angeles for a pair of shoes that cost $35.00?
Answer:
$36.75
Step-by-step explanation:
The sales tax rate = 5 = 0.05 [Divide by 100 to convert in decimal]
The cost of a pair of shoes = $35.00
Tax amount to pay = Tax rate × Cost of a pair of shoes
5% of 35 = 1.75
35 + 5% = $36.75

What is true of the data in the dot plot? Check all that apply.
Number of Minutes Shelly Spent Waiting for the Bus Each Morning
A dot plot going from 10 to 15. 10 has 2 dots, 11 has 4 dots, 12 has 0 dots, 13 has 3 dots, 14 has 6 dots, 15 has 1 dot.
The center is 13.
The center is 14.
The peak is at 14.
It has two clusters.
It is skewed left.
The spread is from 13 to 15.
The person waited for the bus 16 times.
Answer:
True answers for data in the plot are
The center is 13
The center is not 14
The Peak is 14.
It has three clusters
It is not symmetric to left or right it is bi-modal.
It is has a range from 10 to 15 most number of data points are 13 to 15.
Total number times Shelly waited is 16 times.
Step-by-step explanation:
While taking cumulative frequency 56.75 percentage comes in 13%.
It is the center point of the data.
The 14 is not the center as it shows 93rd percent.
It has three clusters 0-2 has one cluster,2-4 has 2nd cluster,5-8 third.
It is not skewed on the left is has bi modal frequency has two heights.
The person indeed waited for 16 times adding total dots.
There was a zero 12 which created bi-modal distribution

500.
Solution: 210 is 42% of X
Equation: Y = P% * X
Solving our equation for X
X = Y/P%
X = 210/42%
Converting percent to decimal:
p = 42%/100 = 0.42
X = 210/0.42
X = 500
