Answer:
Step-by-step explanation:
2 lb bag to 4 sq ft = 1 lb bag to x sq ft
2 / 4 = 1 / x
cross multiply because this is a proportion
(2)(x) = (1)(4)
2x = 4
x = 4/2
x = 2 <==== so a 1 lb bag covers 2 sq ft
Answer:
6
Step-by-step explanation:
10x6=60-2=58
(a) the slope is 2 and y-intercept is 15
slope is the factor in front of x
y-intercept is obtained by setting x=0: y=2*0+15 = 15
(b) the rate of change (aka slope) is 2 baskets per hour. This means that every additional hour of picking there are 2 more baskets of berries than before. The initial amount is 15. This means that there were 15 baskets of berried picked before starting counting the hours.
I hope this helps you
length =x+2
width =2x-5
56=2 (x+2+2x-5)
28=3x-3
x=31/3
