Question

use the function p=7d +11 to find the value of p when d =4

Answer 1

use the function p=7d +11 to find the value of p when d =4​

we have the function

$p=7d+11$

substitute the value of d=4 in the given equation amd solve for p

$\begin{gathered} p=7\cdot4+11 \\ p=28+11 \\ p=39 \end{gathered}$

therefore

the answer is

p=39

Part 2

use the function a=3m +7to find the value of a when m=6

we have

$a=3m+7$

For m=6

substitute

$\begin{gathered} a=3\cdot6+7 \\ a=18+7 \\ a=25 \end{gathered}$

answer is

a=25

Part 3

use the function w=9b+18 to find the value of w when b =1

we have

$w=9b+18$

For b=1

substitute

$\begin{gathered} w=9\cdot1+18 \\ w=9+18 \\ w=27 \end{gathered}$

answer is

w=27
