We can put this word problem into an equation.
1/3x = 7
Now we just have to solve for x. To find x we need to multiply by three on both sides.
1/3x = 7
*3 *3
-------------
x = 21
So it will take 21 hours to paint one wall.
Hey!
-------------------------------------------------
Steps To Solve:
4x - 32 = -8
~Add 32 to both sides
4x - 32 + 32 = -8 + 32
~Simplify
4x = 24
~Divide 4 to both sides
4x/4 = 24/4
~Simplify
x = 6
-------------------------------------------------
Answer:
x = 6

Hope This Helped! Good Luck!
<span>The area of a square is (length of side)^2 , the perimeter of a square is 4*(length of side)
Then your answer is 4 * sq rt (506.25 f`t^2) = 4 * 22.5 ft =
= 90 ft of fence</span><span>Source(s):</span>
Step-by-step explanation:
If we let the width be w, then the length is w+3.5.
This means that w(w+3.5)=11
w^2 + 3.5w - 11 = 0
2w^2 + 7w - 22 = 0 (multiply both sides by 2)
(2w+11)(w-2)=0
w = -11/2 or w = 2 (disregard w = -11/2 as distance is positive)
This means that w=2, and thus the length is 2+3.5=5.5
Answer:
Stefanie bought 10 erasers
Step-by-step explanation:
We can establish the following equation:
TP = NP*PP + NE*EP
Where:
TP = Total price; (4.25)
NP = Number of pencil packages; (1)
PP = Pencil Package's Price; (1.75)
NE = Number of erasers; (What we are looking for)
EP = Erasers Price; (0.25);
Then:
4.25 = 1*1.75 + NE*0.25;
4.25 - 1.75 = NE*0.25;
2.5/0.25 = NE;
10 = NE.
