the percentage of change is 8℅
Answer:
8 pounds
Step-by-step explanation:
5 3/4 + 2 1/4 = 7 4/4 = 8
Lets rewrite this into point-slope, y=mx+b.
y-8=7(x+3)
y-8=7x+21
y=7x+29
Now we can find the slope, which is 7. Now, because this is a linear line, we can substitute points to find which answer is correct.
Option A)
(8)=7(-3)+29
8=-21+29
8=8 TRUE
Option A is correct,

point: (-3, 8)</span>
Answer:
The big container holds 30 gallons and the small container holds 20 gallons
Step-by-step explanation:
Let
The big container = x
Small container = y
The big container can hold 10 gallons less than twice the small
x = 2y - 10
Total gasoline in both containers = 50 gallons
x + y = 50
Substitute x = 2y - 10 into the equation
2y - 10 + y = 50
3y = 50 + 10
3y = 60
Divide both sides by 3
y = 60 / 3
= 20
y = 20 gallons
Recall,
x + y = 50
x + 20 = 50
x = 50 - 20
= 30
x = 30 gallons
The big container holds 30 gallons and the small container holds 20 gallons
