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)
Ii.First ,expand: 5(x-2)=32
5x-10=32
bring 10 to the other side (add it to 32)
5x=42
divide both sides by 5 to get x
x=42/5
x=8.4
iii.Expand 5+2(x+3)=21
5+2x+6=21
bring 5 and 6 to the other side
2x=21-5-6
2x=10 divide both sides by 2
x=5
Answer:
1 5/24 total gallons remain
Step-by-step explanation:
yellow: 4/3 - 3/4 = 16/12-9/12 = 7/12
green: 5/4 - 3/4 = 5/4-3/4 = 2/4
blue: 7/8 - 3/4 = 14/16-12/16 = 2/16
7/12 + 2/4 + 2/16 = 28/48 + 24/48 + 6/48 =
58/48 or 1 5/24
12^2+5^2= 169
Square root of 169= 13
The answer is 13ft
