gladu [14]

Answer:

A

Step-by-step explanation:

We have the expression k+(2k-10)

We want to find the value when k is -3. So, substitute -3 for k and evaluate:

\Rightarrow (-3)+(2(-3)-10)

Multiply:

=-3+(-6-10)

Subtract:

=-3+(-16)

Add:

=-19

Therefore, our answer is A.

tino4ka555 [31]

Answer:

2x + 4

Step-by-step explanation:

Let R = Ralph's age

and x = Sarah's age

          Then Ralph's age in 4 years = R + 4

       and Sarah's age in four years = x + 4

Thus,                                       R + 4 = 2(x + 4)

Distribute the 2                      R + 4  =     2x + 8

Subtract 4 from each side     R        =     2x + 4

Ralph's age is 2x + 4.
