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

Answer :

Answer:

the answer is -9

Step-by-step explanation:

3(2 - 5)

6 - 15

-9

Answer:

[tex]\boxed{-9}[/tex]

Solution Steps:

______________________________

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

  • [tex]r=2[/tex]
  • [tex]t=-7[/tex]
  • [tex]u=-5[/tex]
  • [tex]3(2+(-5))[/tex]

 - 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:

  • [tex]3(2+(-5))[/tex]

2.) Subtract 5 from 2:

  • [tex]2-5=-3[/tex]

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

Equation at the end of Step 2:

  • [tex]3(-3)[/tex]

3.) Multiply 3 and −3:

  • [tex]3[/tex] × [tex]-3=-9[/tex]
