Solve the inequality of -2/3 > z/5

patriot [66]

Answer:

$\boxed{\bold{Z < \frac{-10}{3} }}$

Explanation:

Simplify both sides of inequality

-2 / 3 > 1 / 5 z

Flip equation

1 / 5 z < -2 / 3

Multiply both sides by 5

(1 / 5 z) 5 < (-2 / 3) 5

Z < -10 / 3

Kamoira bought 8 pizzas for $131.36. Each pizza cost the same amount. What was the cost of each pizza in dollars and cents?

Veseljchak [2.6K]

Step-by-step explanation:

so, you don't know what a division is for ?

it is to ask things like "how often does one number fit into another number", or "how big will each piece be, if I split something into a certain number of equally sized pieces ?".

this is what we need here.

8 pizzas for $131.36. and each pizza costs the same. you see how that connects to what I just described above ?

to find how much each pizza cost, we need to divide the total price by 8, to find the size (= here the price) of each of the equally big parts of the total price.

131.36 / 8 = $16.42
