First, you would substitute z with 12 since z = 12.
12 ÷ 3 - 5 (12) + 4 (12 - 2).
Then, you would follow the order of operations.
12 ÷ 3 - 60 + 40
4 - 60 + 40
-56 + 40
-16
So your answer is -16.

Solve the following problems mentally and match it to its corresponding solution.
HACTEHA [7]

Answer:

<h3>1. t=10</h3><h3>2. t=4</h3><h3>3. t=40</h3>

Step-by-step explanation:

Isolate the term of t from one side of the equation.

<h3>1. 4t=40</h3>

First, you have to divide by 4 from both sides.

4t/4=40/4

Solve.

Divide the numbers from left to right.

40/4=10

<h3><u>t=10</u></h3>

<h3>2. 10+t=14</h3>

<u>First, change sides.</u>

t+10=14

<u>Then, subtract by 10 from both sides.</u>

t+10-10=14-10

<u>Solve.</u>

<u>Subtract the numbers from left to right.</u>

14-10=4

<h3><u>t=4</u></h3>

<h3>3. 70-t=30</h3>

First, subtract by 70 from both sides.

70-t-70=30-70

Solve.

30-70=-40

<u>Rewrite the problem down.</u>

-t=-40

Divide by -1 from both sides.

-t/-1=-40/-1

<u>Solve.</u>

<u />

<u>Divide the numbers from left to right.</u>

-40/-1=40

<h3><u>t=40</u></h3>

  • <u>Therefore, the correct answer is t=10, t=4, and t=40.</u>

I hope this helps! Let me know if you have any questions.
