QuestionFind the value of $4y + 9z$ for $y=5$ and $z=4$ .

Studdy Solution

STEP 1

Assumptions1. The value of $y$ is5. The value of $z$ is4

STEP 2

We need to substitute the given values of $y$ and $z$ into the expression. The expression is $4y +9z$

STEP 3

Substitute $y =5$ and $z =$ into the expression.
$(5) +9()$

STEP 4

Calculate the value of the expression.
$4() +9(4) =20 +36$

STEP 5

Add the two values to get the final result.
$20 +36 =56$ The value of the expression when $y=5$ and $z=4$ is56.
