21 - (3 x 4)
3 x 4 is 12, so it becomes 21 - 12.
21 - 12 = 9
One yard is 36 inches, 1.5 feet is 18 inches.
So the answer is...
(36+3)*18*20
= 39*18*28
= 702*28
= 19,656
Answer:
3.5 inches
Step-by-step explanation:
create a proportion:
inches / miles = inches / miles
let 'x' = distance in inches
<u>1/4</u> = <u> x </u>
18 252
18x = 252(1/4)
18x = 63
x = 63 / 18
x = 3.5
Answer:
x = 2
Step-by-step explanation:
24 - 7x = 10
Rearrange terms,
-7x + 24 = 10
Subtract 24 from both sides,
-7x + 24 - 24 = 10 - 24
-7x = 10 - 24
-7x = -14
Divide by sides by -7,


x = 2
