Answer:
6 acres
6/7 lb left
Step-by-step explanation:
Each 7/8 of a lb is good for 1 acre.
He has 6 lb.
The first step is to see how many amounts of 7/8 lb are in 6 lb.
This is a division problem.
6 / (7/8) = 6/1 * 8/7 = 48/7 = 6 6/7
6 lb is 6 6/7 portions of 7/8 lb.
Since each 7/8 lb is good for 1 acre, he has enough for 6 6/7 acres.
He can plant 6 whole acres.
The remaining seed is 6/7 lb.
Answer:
The desired equation is y = 3x + 2
Step-by-step explanation:
A NEW LINE parallel to y = 3x + 3 has an equation that is identical to y = 3x + 3 except that the y-intercept will be different.
Start with y = 3x + 3; replace x with -1 and y with -1 (which come from the given point): -1 = 3(-1) + b. Then -1 = -3 + b, and b must be +2.
The desired equation is y = 3x + 2.
