I'm guessing it's like this
example
18=2*3*3=(2¹)(3²)


315/5=63
63/3=21
21/3=7

factored form is 3*3*5*7=(3²)(5¹)(7¹)

Answer:

yo i only got number 4 for you but here it goes.......: 0.70x+18y-5

Step-by-step explanation:

(0.75x  -  12y) + (-5  +  6y  -  0.5x)

regroup to the variables : (0.70x-0.5x) + (12y+ 6y-5)

put it together: (0.70x)+(18y-5)

you cant add unlike terms so you remove the parenthesies and your done.

Let Jenny = J

Let Mica = M

J = M + 4

Now you have to represent 5 years ago

J - 5 = 2*(M - 5)

J - 5 = 2M - 10                Substitute J = M + 4 Into this equation

M + 4 - 5 = 2M - 10        Combine terms on the left

M - 1 = 2M - 10               Add 10 to both sides    

M - 1 + 10 = 2M              Combine one the left

M + 9 = 2M                    Subtract M from both sides

9 = 2M - M              

9 = M                             Answer Miki

J = M + 4                       Substitute Miki's age for M

J = 9 + 4                         Answer Jenny

J = 13

Answer:

Jenny = 13

Mika = 9
