Answer:

See below.

Step-by-step explanation:

7x^2 = 343 Divide both sides by 7

7x^2/7 = 343/7

x^2 = 49 Take the square root of both sides.

sqrt(x^2) = sqrt(49)

x = +/- 7

Answers

- 7
sqrt(49)
- sqrt(49)

I think the last two are kind of iffy. I'm not sure you can call them solutions, but the question probably assumes they are. If you use all four answers and get it wrong, them submit +7 and - 7.

There are 12 team members. They each ate 3 slices of pizza. Each pizza was cut into 8 slices. What fraction of the pizza did the

ICE Princess25 [194]

First I'd assume each "pizza" refers to the number of pizza pies. Each pizza pie includes 8 slices. Since there are 12 team members, and each at three, therefore 36 slices total were eaten by each of the 12 team members (12x3). Since you know that 8 slices make up a pizza pie, how many pies do you need to have at least 36 slices? The answer is 5 pies (or 40 slices). So the team ate 36/40 slices or 9/10 pizzas.
