Standard form: Ax + By = C
Y = 7/5x - 2
Subtract y and add 2
7/5x - y = 2
Multiply by 5
Solution: 7x - 5y = 10
Answer:
I think it's B
Step-by-step explanation:
If 8= 538 Ib. then take the (538) and divide that by 8. <---- 8 for the 8 uniforms.
Your math should look like this: 538/8= about 67 pounds.
Then do 67*8= 536. (You started at 532 Ib.) this is just 2 pounds off*
So, your answer should be *67* pounds.
*Use paper and a pencil! Sometimes doing mental math can be challenging with a problem like this. So use paper and a pencil, checking your answer wont hurt either!*
109-36=73
73/3=24.333..
LONGEST PIECE= 60
SHORTEST= 19
THIRD= 30
Answer:
Her average speed is 48 miles per hour.
Step-by-step explanation:
We solve this question using a system of equations.
The speed equation is:

In which s is the speed, d is the distance, and t is the time.
Gabriella drives her car 320 miles and averages a certain speed.
So 
Then

If the average speed has been 6 miles less she could have traveled only 280 miles in the same length of time.
So, which s - 6, d = 280.

From the first equation:



Replacing:







Her average speed is 48 miles per hour.
