Answer: 20 ft
Step-by-step explanation:
The mirror is set away from the flagpole on the same scale set away from her.
The distance she stand's away from the mirror is 1/4 of the length of the distance between the mirror and the flag pole because she's 1/4 of the flagpole's size.
This means her size x4 is the size for the flag pole. This checks out because 12x4=48
So to find the height we must do 5x4
5x4=20
639÷9=71. You can check your answer by doing 71x9=639
Answer:
x=9
Step-by-step explanation:
First, distribute the 2 and each value in the parentheses.
2*x+2*5. This is the first half of the equation.
2*x+2*5= 3x+1 You can then simplify
2x+10=3x+1 Subtract 3x from both sides
(2x-3x)+10=(3x-3x[cancels out])+1
-x+10=1 Now subtract 10 from both sides
-x(10-10[cancels out to 0])=(1-10)
-x=-9 Since x is negative we need to solve for positive
x=9
I can help! You take the amount of money earned (734.15) divided by the amount of hours worked (37). So 734.15 divided by 37= 19.84189189189189
