Answer:
Step-by-step explanation:
18 (d/2-5) = 171
1. If you apply the Distributive Property first, what operation will you need to use last?
a. Multiplication
b. Addition
c. Division
d. Subtraction
18 (d/2-5) = 171
[tex]18(\frac{d}{2}-5)=171 \\\\18(\frac{d}{2})+18(-5)=171\\\\\frac{18d}{2} -90=171\\\\9d-90=171\\\\+90\ \ \ \ \ +90\\\\9d = 261\\\\/9 \ \ \ \ /9[/tex]<== division was used last
[tex]d = 29[/tex]
2. If instead, you divide first to solve the equation what operation would you need to use last?
a. Division
b. Multiplication
c. Subtraction
d. Addition
Recall that in the previous question, we started with multiplication and ended with division. Now, it's switched. Division comes first, then multiplication.

StartFraction 10 over 20 EndFraction = StartFraction x over 1,500 EndFraction. StartFraction 10 times 30 over 20 times 30 EndFraction = StartFraction x over 1,500 EndFraction. 300 = x.
He should have found the average of the number of rock songs by averaging 4 and 6 to get 5.
He did not multiply the numerator and denominator by the correct number to equal 1,500.
His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion.
He can only solve the proportion by multiplying the numerator and denominator by a common multiple.
He should have multiplied the numerator and

John keeps track of his father's driving to pass the time on a trip to Grandma's. He records the distance each hour, and he will graph the results. If the pattern of mileage change continues, how far will they have driven in 11 hours?
Hours Miles (x, y)
1 70 (1, 70)
2 140 (2, 140)
3 210 (3, 210)
4 280 (4, 280)
560 miles
700 miles
350 miles
770 miles
Answer:
770 miles
Step-by-step explanation:
First, find the slope (m) of the pattern, using any two points from your data set.
Slope (m) = [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
(1, 70) and (3,210)
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{210-70}{3-1}\\m=\frac{140}{2}\\m=70[/tex]
y = mx + b
y = 70x + b
(1, 70)
y = 70x + b
70 = 70(1) + b
70 = 70 + b
-70 -70
0 = b
y = 70x + b OR y = 70x
Now we find how he has driven in 11 hours
y = 70x
y = 70(11)
y = 770
Therefore, he will have driven 770 miles in 11 hours.

Crayons are on sale for $.25 for a pack of 16. This was down from the normal price of $.75 per 16 pack. What is the percent discount buyers are getting per crayon at this sale price?
Answer:
2/3 or 66.7%
Step-by-step explanation:
The old price of 1 crayon was 75/16 or about 4.69 cents
The new price of 1 crayon is 25/16 or about 1.56 cents
now to find the discount you can find out how much percent of 4.69 is 1.56 and then subtract from 1 if you use a fraction or 100 if you use percentage to get the final answer.
(1.56/4.69) * 100= 1/3
1 - 1/3= 2/3

Annabelle and Katherine work at a furniture store. Annabelle is paid $235 per week plus 10% of her total sales in dollars, x x, which can be represented by g ( x ) = 235 + 0.1 x g(x)=235+0.1x. Katherine is paid $1714 per week plus 1.5% of her total sales in dollars, x x, which can be represented by f ( x ) = 1714 + 0.015 x f(x)=1714+0.015x. Determine the value of x x, in dollars, that will make their weekly pay the same.

A store charges 8% tax on every dollar spent. The table shows the tax amount for several different purchases. How much tax would there be on a $200 purchase?
Answer:
This online sales tax calculator solves multiple problems around the tax imposed on the sale of goods and services.
Answer:
$1.6
Step-by-step explanation:
If 8% is charged for each $. Tax charged for $1 = 8/100 which is equal to 0.08.
Tax Amount payed
$0.08 -----------> $1
$y ------------> $20
This is directly proportional. Therfore cross multiply the values.
y × 1 = 20 × 0.08
y × 1 = 1.6
y = 1.6/1
y = 1.6
Therefore $1.6 is the amount of tax charged for $20

(5x-4 + 5x -4) + (5x +5x) = 10x -8 + 10 x = 20x -8

we plug in our units to get 36pi = pi(r^2)(12)
we divide 12 from each side to get 3pi=pi(r^2)
divide pi on each side to get 3 = r^2
square each side to get the radius = sqrt 3
find the diameter by multiplying sqrt3 times 2 = 3
