The senior classes at High School A and High School B planned separate trips to New York City. The senior class at High School A
Nezavi [6.7K]
Class A: 6v + 8b = 202

Class B: 12v + 16b = 284

Solve using the elimination method:
since 6v and 12v are perfect for elimination, multiply the class A equation by 2 so that the van variable cancels out: 

12v + 16b = 404
12v + 10b = 284

Then subtract the bottom equation from the top:

6b = 120
b = 20 

Now you know that each bus can hold 20 students.
Just plug this into one of the original equations to solve for vans:

6v + 8(20) = 202
6v + 160 = 202
6v = 42 
v=7 

So then you know that each van can hold 7 students. 

Check:
12 (7) + 10 (20) = 284

8.37 Sale prices at the Ajax Outlet Store are 50% below original prices. On Saturdays, an additional discount of 20% off the sal
givi [52]

Answer:

Given:

  • Sale prices at the Ajax Outlet Store are 50% below the original prices.
  • On Saturdays, an additional discount of 20% off the sale price is given.

To find:

  • The Saturday price of a coat whose original price is $180.

The formula used to calculate the percentage is (value/total value)*100%.

Step-by-step explanation:

Step 1 of 2

The original price of coat = $180



Ajax always sells at 50% discount

So their sale price = $90

Step 2 of 2

On Saturdays they sell 20% less

Which implies-

1/5*90 = 18

90-18=72

They sell at $72 on Saturday.

1/8(p+24)=9<br> Distributive property
Grace [21]

Hey there!

1/8(p + 24) = 9

1/8(p) + 1/8(24) = 9

1/8p + 3 = 9

SUBTRACT 3 to BOTH SIDES

1/8p + 3 - 3 = 9 - 3

CANCEL out: 3 - 3 because it gives 0

KEEP: 9 - 3 because it help solve for the p-value.

NEW EQUATION: 1/8p = 9 - 3
SIMPLIFY IT!

1/8p = 6


MULTIPLY 8 to BOTH SIDES

1/8p * 8 = 6 * 8

CANCEL out: 1/8 * 8 because it gives 1

KEEP: 6 * 8 because it gives the p-value.


NEW EQUATION: p = 6 * 8

SIMPLIFY IT!

p = 48


Therefore, your answer is: p = 48


Good luck on your assignment & enjoy your day!
