Answer:
b = 15.7 -2a
Step-by-step explanation:
You are asking us to solve for b
2a +b = 15.7
Subtract 2a from each side
2a-2a+b = 15.7 -2a
b = 15.7 -2a
Answer:
-3 = n
Step-by-step explanation:
11(n − 1) + 35 = 3n
Distribute
11n -11 +35 = 3n
Combine like terms
11n +24 = 3n
Subtract 11n from each side
11n -11n +24 = 3n -11
24 = -8n
Divide by -8
24/-8 = -8n/-8
-3 = n
Answer:
Step-by-step explanation:
It is a rectangle, so both sides are equal. Thus 2x+6=5x-9
SOLVE, SUBTRACT 2x
6=3x-9 THEN ADD 9
15=3x THEN divide by 3
5=x
Plug in x to either side 2(5)+6, to get side length of 16
Then area of a rectangle is lengthxwidth=AREA
substitute what you know 16(y)=48
Divide by 16, thus y=3
