Answer:
one solution
Step-by-step explanation:
Given
3x - 2 = 4x + 5 ( subtract 4x from both sides )
- x - 2 = 5 ( add 2 to both sides )
- x = 7 ( multiply both sides by - 1 )
x = - 7 ← the one solution
Answer:
B.)8ft
Step-by-step explanation:
Set up a proportional to the roof slope:
2/5 = x/20
Cross multiply:
40/5 = 5x/5
x=8ft
28 / 7 = 4
3 x 4 = 12
It’ll take him 12 minutes
Each Interior Angle = 180 - (360 / number of sides)
# of sides = -360 / (Each Interior Angle -180)
# of sides = -360 / (144 -180)
# of sides = -360 / -36
# of sides = 10
