Answer:
The two numbers are 37.5 and 25.5
Step-by-step explanation:
Comment
Let the two numbers be x and y
Equations
x + y = 63
x - y = 12
Solution
Add the two equations. The ys cancel out.
2x = 75 Divide by 2
2x/2 = 75/3 Do the division
x = 37.5
Now use one of the given equations to solve for y
x + y = 63
x = 37.5
37.5 + y = 63 Subtract 37.5 from both sides
37.5-37.5+y= 63 - 37.5 Collect the like terms on both sides
y = 25.5
Check
x - y =? 12
37.5-25.5 =? 12
12 = 12
So to find the area of a rectangle, the formula is
B (base) x H (height)= A (area)
12 cm x H = 250.8 cm^2
H= 250.8 / 12
H= 20.8 cm

Answer:
14.8
Step-by-step explanation:
If you are allowed a calculator, the formula to find the percentage is found by multiplying the percentage by the whole number. For example, when you put in the calculator, 18.5% x 80= 14.8
14.8 being your answer. I hoped this helped!
