Question

Solve each equation for d when c = 0
10c+ 4d = 40

Answer 1

Answer: " d = 10 " .
________________________
Step-by-step explanation:
_________________________
Given: " 10c + 4d =40" ; Solve for "d" ; when: "c = 0" ;
_________________________
Plug in "0" for "c" ; and simplify:
______________________
10(0) + 4d = 40 ;
______________________
0 + 4d = 40 ;
_____________________
4d = 40 ;
_____________________
Divide each side of the equation by "4"; to isolate "d" on one side of the equation; & to solve for "d" ;
______________________
4d / 4 = 40 / 4 ;

to get:
______________________

d = 10 .

Answer 2

Hello!

The answer would be d = 10. Solve it like this. (v v v)

10 * 0 + 4 * d = 40 ---> 0 + 4 * 10 = 40

0 + 40 = 40

40 = 40

Hope this helps! ☺♥
