7s + 5 for s = 3 evaluate the expression

7x3 + 5 = 21+5 = 26 it's just plugging in 3 for the value of s

Answer: 26

Step-by-step explanation: Here, we have the expression 7s + 5 and we want to evaluate the expression when s is equal to 3.

To evaluate an expression, we simply plug the value

of the variable into the expression and solve.

So here, since s is equal to 3,

we have 7 (3) + 5.

Notice that I used parentheses around the 3. It's always a good idea to use parentheses when substituting/plugging in numbers for variables.

Solving from here, 7 (3) is equal to 21.

So we have 21 + 5 which is equal to 26.

So the value of our expression

when s is equal to 3 is 26.
