Answer:
x= 5.25
Step-by-step explanation:
You have to get x alone, so do inverse operations.
(Basically, reverse what it is)
4(x-3)=9
divide 4 by both sides to get rid of 4 on left side
9/4 = 2.25
(x-3) = 2.25
Now add 3 to both sides, to get x alone
2.25 + 3 = 5.25
x=5.25
Check work
4(5.25-3) = 9
4(2.25) = 9
9=9
Answer:
perimeter is 36 inches and the area is 32 square inches
60% of what number is 348?
The answer is 580.
350x300=105000m squared
1km=1000m
So, 105000=105km squared
Answer:
A = 49 ft^2
Step-by-step explanation:
The perimeter of a square is given by
P = 4s where s is the side length
28 = 4s
Divide each side by 4
28/4 = 4s/4
7 =s
We want the area
A = s^2
A = 7^2
A = 49 ft^2
