had enough flour, sugar, and spices to make 9 apple pies. She needs 4 apples for each pie. How many apples will Randy and Michelle have to pick?

36 apples, you need to multiply 9 and 4 since there are 9 pies and 4 apples in each pie

X/3=2
x=6

x/5=3
x=15

x/7=2
x=14

Each time, you multiply both sides by the denominator.

Hope this helps :)

Answer:

A.

${b}^{2} + 3b - 3 = 0$

Step-by-step explanation:

${b}^{2} + 3b - 3 = 0 \\ because \: \: {b}^{2} < 4ac \\ {b}^{2} = {3}^{2} = 9 \\ 4ac = 4 \times 1 \times - 3 = - 12 \\ hence : {b}^{2} < 4ac$
