So it's easier to calculate if you figure out how much time it took her to finish 25% of the wall. Since it took her 45 minutes to do 75%, it took her 15 minutes to do 25%. Then you just multiply.
Therefore, it takes her 60 minutes to finish building her wall.
Answer:
The 2 tables are linear, the second thing with the 10n-5 is exponential and the third thing is not a function.

Solving:
1)
-58 - 6x = 42 + 4x
</span>Pass the numbers with letter to the left and the numbers without letter to the right, changing the signal as they change sides.
<span>- 6x - 4x = 42 + 58
- 10x = 100 simplify by (-1)
10x = - 100

2)
37 + 5x = -2x - 33
</span>Pass the numbers with letter to the left and the numbers without letter to the right, changing the signal as they change sides.
<span>5x + 2x = - 33 - 37
7x = - 70
</span>


<span>
3)
27 - 9x = -6x - 39
</span>Pass the numbers with letter to the left and the numbers without letter to the right, changing the signal as they change sides.
- 9x + 6x = - 39 - 27
- 3x = - 66 simplify by (-1)
3x = 66

Answer:
35
Step-by-step explanation:
Answer:

Step-by-step explanation:
So we have the equation:

Combine like terms:

Add 4 to both sides. The left side cancels:

Divide both sides by 8:

Thus, the value of x is 5.
