Answer:

one, no, one, infinitely

Step-by-step explanation:

a. you can get 7x = 21 - 21 = 0 ==> x = 0

b. subtract 12x from both sides ==> get 15 = -15, which is not true

c. -5x-5x=25+25 ==> -10x = 50 ==> x = -5

d. get -2x -6 -7 = -2x - 6 - 7 ==> so it's infinitely

NikAS [45]

Answer:

point-slope form: y-y1=m(x-x1)

y-(-1)= -3/4(x-(-4))

y+1= -3/4(x+4)

Frank is using a cookie recipe that calls for 2 ¼ cups of flour. The recipe yields 20 cookies. How much flour would be needed to
larisa86 [58]

Hey there! I'm happy to help!

How many times does 20 go into 48?

48/20=2.4

So, we multiply our amount of flour for 20 cookies by 2.4.

2.25×2.4=5.4

Therefore you would need 5.4 or 5 2/5 cups of flour to make 48 cookies.

Have a wonderful day! :D
