Answer: " d = 10 " .
________________________
Explanation:
_________________________
Given: " 10c + 4d =40" ; Solve for "d" ; when: "c = 0" ;
_________________________
Plug in "0" for "c" ; and simplify:
<span>______________________</span>
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 .

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! ☺♥

To solve 49^3x = 343^2x+1, write each side of the<br> equation in terms of base<br> DONE

Nostrana [21]

Answer:

no solution

Step-by-step explanation:

49^3x = 343^2x+1

49 = 7^2 and 343 = 7^3

7^2 ^3x = 7^3 ^2x+1

we know that a^b^c = a^ (b*c)

7^(2 *3x) = 7^(3 *(2x+1))

7^(6x) = 7^(6x+3)

The bases are the same so the exponents have to be the same

6x = 6x+3

Subtract 6x from each side

0 =3

This is never true so there is no solution
