Answer:
63
Step-by-step explanation:
In these 9 bags, each must have 7 gumdrops. So, we can add 7 nine times to itself. 7 + 7 + 7 + 7 + ... = 63
OR HERE'S A FASTER WAY *WINK WINK*
Instead of doing repeated addition, we can <u>multiply</u> 7 and 9 together.
<u>Why multiply?</u>
We're going to multiply 7 x 9 so that it means seven gumdrops for <em>each</em> of nine bags.
7 x 9 = 63.

Answer:
Step-by-step explanation:
We need x first.
AB = DE
12 = 3x -3
4 = x -1 . . . . . divide by 3
5 = x
Now, we can find y.
∠C = ∠F
7x +y = 55
y = 55 -7x = 55 -7(5)
y = 20
No you multiply the number by itself however much the exponent number is.
for example: 6^2 it would be 6x6= 36
5^3 it would be 5x5x5= 125
