7x - 4 = 5x + 15

7x - 5x = 15 + 4

2x = 19

x = 19/2

7x - 5x = 15 + 4

2x = 19

x = 19/2

Which of the following equations could not be used to solve the problem?
50x + 25(30 - x) = 1225
50(30 - x) + 25x = 1225
25x + 50x = 30(1225) **Weegy:** The last equation could not be used. **User:** Janet has three times as many dimes as nickels and twice as many quarters as nickels. If she has $3.40 in all, how many nickels, dimes, and quarters does she have?
If n represents the number of nickels Janet has, which of the following equations could be used to solve the problem?
5n + 10n + 25n = 340
n + 3n + 2n = 340
5n + 30n + 50n = 340 **Weegy:** 5n + 10n + 25n = 340 **User:** If x = -3, then x 2-7x + 10 equals

15 ÷ 3 · (-2) + |-10|

= 5(-2) + 10

= -10 + 10

= 0

= 5(-2) + 10

= -10 + 10

= 0

If x = -3,

x^2 - 7x + 10

= (-3)^2 - 7(-3) + 10

= 9 + 21 + 10

= 30 + 10

= 40

x^2 - 7x + 10

= (-3)^2 - 7(-3) + 10

= 9 + 21 + 10

= 30 + 10

= 40
