Gina is having a party and wants to spend less that $380. She has already spent $300. The only item left on her list is pizzas, which cost $10 each. How many pizzas, x, can she purchase and stay under her budget? Select the inequality that includes the largest number of pizzas she can purchase and still stay under her budget.

x < 8 (max number of pizzas is 7)

Step-by-step explanation:

set up an inequality where x = number of pizzas

total < 380 (this is given)

total = 300 + 10x (she already spent 300, and each pizza costs 10 each)

300 + 10x < 380

now solve for x

300 + 10x < 380

10x < 80

x < 8

if she wants to spend less than $380, she needs to buy less than 8 pizzas, so she can buy 7 pizzas at most

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
