Answer:2x - 5cm + 3x +2cm + 2x - 1cm=59cm
2x + 3x + 2x + 2cm + 1cm - 5cm=59cm
7x - 2cm=59cm
7x - 2cm + 2cm=59cm + 2cm
7x=61cm
X=8 5/7cm

Answer:
Ann drove 312 miles in 8 gallons.
Step-by-step explanation:
Distance covered by Ann's car = 117 miles
Gallons of gas spent by Ann's car to cover 117 miles = 3 gallons
Unit rate = 117 miles / 3 gallons
= 39 miles per gallon
so Ann's car can go 39 miles in one gallon of gas.
- Given that Ann used 8 gallons of gas.
Therefore,
Distance covered by Ann's car in 8 gallons = 39 × 8
= 312 miles
Therefore, Ann drove 312 miles in 8 gallons.
Answer:
y = -8/9
Step-by-step explanation:
2 ×(7) - 9 y = 22
14 - 9y = 22
9 y = -8
y = -8/9
Answer:
The answer to your question is Area = 50.27 m²
Step-by-step explanation:
Data
Area = ?
Diameter = 8 m
π = 3.1416
Formula
Area = πr²
Process
1.- Find the length of the radius
radius = diameter/2
- Substitution
radius = 8/2
- Result
radius = 4 m
2.- Find the area of the circle
Area = (3.1416) (4)²
Simplification and result
Area = (3.1416) (16)
Area = 50.27 m²
