Use transformations to solve the equation. c – 16 = 41 A. c = –57 B. c = –25 C. c = 25 D. c = 57

baherus [9]

You should just transfer -16 to the other side so you gonna have : c = 41 + 16 so c = 57 :))

Jake ate 1/6 of the cookies at the party if he ate 5 cookies how many cookies were there in all

egoroff_w [7]

If Jake ate 1/6 of the cookies at the party and we know he ate 5 cookies. We must find out how many cookies there are in all.

$\frac{1}{6} = \frac{5}{x}$

Now x here represents how many total cookies are at the party.

We have to simply find out what 1 was multiplied by to get 5.

We can do this by dividing.

5 ÷ 1 = 5

So the numerators (the top numbers) were multiplied by 5. We can do the same to the denominators (the bottom numbers) to get the total number of cookies.

Lets multiply.

6 x 5 = 30

So the total number of cookies is 30

Good Luck! <3
