As they are similar corresponding sides are in the same ratio, so
18/15 = x / 4
x = 4*18 / 15
x = 4.8 answer
we know there are 5280 feet in 1 mile, and there are 3600 seconds in 1 hour.
Answer:
They are 7 and 11. 11 + 7 = 18, 11 - 7 = 4.
Answer:
a. x = total - $5
b. x = $6
c. x = $10
Step-by-step explanation:
a. pen + book = total
Let x = book
$5 + x = total
x = total - $5
b. pen + book = total
Total = 411
$5 + x = $11
x = $11 - $5
x = $6
c. pen + book = total
Total = $15
$5 + x = $15
x = $15 - $5
x = $10
