The answer is 52.
65 x 0.8 = 52.
Answer:
x = 5.5 (nearest tenth)
Step-by-step explanation:
let x be the length of 1 side
given area of square poster is 30 in²
and
Area = (length of 1 side )²
hence
30 = x²
x = √30
x = 5.4772
x = 5.5 (nearest tenth)
Answer: 2 years 1 month
Step-by-step explanation:
2 years 1 month at $100 a month = $2,500
$720 x 2 years = $1,440
$720 / 12 months = $60
$1,440 + $60 = $1,500
$4,000 - $1,500 = $2,500
Shoes= 10
Man= 5
Tie= 4
So, 10+5*4= 30 <— Answer
How to get variables:
Shoes:
3 shoes are equal to 30, so to find the value of the shoes use 3x=30. X=10
Man:
2 men and a shoe is equal to 20. So, 2x+10=20
2x=10
X=5
Tie:
2 ties and a man are 13. So,
2x+5=13
2x=8
X=4
