He should buy two 5 pound bags and one 2 pound bag.
Answer:
y = 2x - 1 is the required equation
Step-by-step explanation:
slope(m) = (3-7)/(2-4)
m = -4/(-2)
so, m = 2
Now,
y = mx + b
or, y = 2x + b
so, 3 = 2*2 + b
or, 3 = 4 + b
so, b = -1
equation would be y = 2x - 1
1)y=5-2/3
y=13/2
2) t=4 1/2+ 4 1/2
t=9
3) w= 3 5/8+2 7/12
w=29/8+31/12
w=15/2
Answer:
56x+24y-8
Step-by-step explanation:
6 + 2 (7x +3y-1)
8(7x+3y-1)
56x+24y-8
