Question

Evaluate this expression if r = 2, t = -7, and u = -5 3(r+u)

Answer 1

Answer:

the answer is -9

Step-by-step explanation:

3(2 - 5)

6 - 15

-9

Answer 2

Answer:

$\boxed{-9}$

Solution Steps:

______________________________

1.) Fill in the given variables into a new equation:

• $r=2$

• $t=-7$

• $u=-5$

• $3(2+(-5))$

 - We do this since it gives us the missing variables, which makes it so we can solve it like any regular equation.

Equation at the end of Step 1:

• $3(2+(-5))$

2.) Subtract 5 from 2:

• $2-5=-3$

 - We do this because we need 1 number, not 2 at the end.

Equation at the end of Step 2:

• $3(-3)$

3.) Multiply 3 and −3:

• $3$ × $-3=-9$
