7 0

ANSWER:
4b + 22 = 5b+ 20-1
4b + 22= 5b +19
subtract 22 OR 19 from each sidE IM GOING TO DO 22.
4b + 22-22= 5b + 19 -22
4b = 5b - 3
subtract 5b from each side.
4b -5b = 5b-3-5b
-1b = -3
a variable cannot be negative so multiply each side by a negative 1. two negatives make a positive.
(-1) -1b = -3(-1)
b=3

Answer:

1. No

2. 1,050 bushels of corn

Step-by-step explanation:

1. A number is proportional if it has a constant ratio to another quantity.

8/12 and 10/25 do not.

2. An acre will produce $\frac{750}{10}$ bushels of corn.

750 divided by 10 is 75. <u>This is 75 bushels per acre.</u>

Then you would multiply 75 and 14.

This equals 1,050 bushels of corn.
