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.

Josiah’s work:
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.
Hope this helps!

help me with this math homework its so hard and confiseing
Answer:
Step-by-step explanation:
the equation for a cone is V= pir^2h
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
The circumference is 3pi.

A bicycle has a listed price of $811.99 before tax. If the sales tax rate is 6.5% , find the total cost of the bicycle with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:698.86
Step-by-step explanation:Bicycle - $655.95
Sales Tax 6.5% = 655.95 x 6.5% = 42.636
Total $655.95 + 42.636 = 698.858 = 698.86 - Total cost of the bicycle with sales tax included.

Answer:
20x - 8
Step-by-step explanation:
Since we have the length and height of the rectangle we just multiply each by 2. This is because the length is the same on both sides and the height is too. The equation would look like this:
(5x-4 + 5x -4) + (5x +5x) = 10x -8 + 10 x = 20x -8

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

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

kristen's hens lay eggs in groups of 10 Meanwhile Colette's hens lay eggs in groups of 4 if both chicken farmers were able to collect the same number of eggs from their chickens this week what is the minimum number of eggs that could have been laid for each farmer
Answer:
20
Step-by-step explanation:
kristen's hens lay eggs in groups of 10 so, it laid eggs 10,20,30,40,50...
Colette's hens lay eggs in groups of 4 so, it laid eggs as 4,8,12,16,20,24...
What is the minimum number of eggs that could have been laid for each farmer? So, you have to find the smallest amount of eggs both hens hatched which is 20.
