Answer:
3x6 = 729x when ever a number has an exponnet yo have to multiply the main number to itself as many times as it says.
So in this case you had to multiply 3 by itself(3) 6 times would be
(3x) x (3x) x (3x) x (3x) x (3x) x (3x) = 729x. And of course bring the variable.
x2 So when theres a varible that is by itself for example (x) you always add a 1 in front of it. so in this case x2 would be 1x2. 1 times itself(1) 2 times would be. (1x) x (1x) = 1x
729 smaller cubes would fit inside the larger cube.

Using proportions, we have that:
- 125% of last year's attendance is of 270.
- 25% of last year's attendance is of 54.
- 100% of last year's attendance is of 216.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
We have that last year's amount is of x, and 125% of that is 270, hence:
1.25x = 270
x = 270/1.25
x = 216.
100% of last year's attendance is of 216.
25% of last year's attendance is given by:
0.25 x 216 = 54.

#SPJ1
Answer:
7+x/2
Step-by-step explanation:
let the number be "x"
seven more- 7+
half of a number- 1/2
=x/2
answer- 7+x/2
M=5
9x5=45
45/9=5
hope this helps you out
