7th grade math help!

Step-by-step explanation:

23B) The equation is 24-x(7)=10

Because she spends twenty four dollars on seven rings which we don't know how much it costs giving us a change of ten dollars

23C) The equations solution:

24-x(7)=10

24-x*7=10

-7x=10-24

-7x=-14

-7x/-7=-14/-7

x=2

23D) Twenty four dollars is spent on seven rings that costs two dollars each, giving a total of fourteen dollars spendings. Therefore the change is ten dollars.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
