Petri did the following problem but got the wrong answer. She needs to correct her mistake and turn the problem back in. (5 - 3) 2 ÷ 3 · 7 + 1 25 - 9 ÷ 3 · 7 + 1 25 - 3 · 7 + 1 25 - 21 + 1 4 + 1 5 What correction does Petri need to make? She needs to add before she multiplies. She needs to multiply 3 times 7 before she divides. She needs to change 25 to 10. She needs to subtract 5 - 3 first.

450

step-by-step explanation:

you get texts and minutes, so why not

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
