Answer:
2.8 gallons 0.5% milk
4.2 gallons 3% milk
Step-by-step explanation:
let 'x' = .5% milk
let 'y' = 3% milk
System of Equations:
x + y = 7
.005x + .03y = 7(.02)
I used the substitution method and solved the first equation for y: y = 7 - x
.005x + .03(7 - x) = .14
.005x + 0.21 - .03x = 0.14
-0.025x + 0.21 = 0.14
-0.025x = -0.07
x = 2.8
7 - 2.8 = 4.2
y = 4.2
I can answer your first question she can do 5 minutes at the most. If she does 20 per minute, for one is 20, for two minutes is 40, three is 60, four is 80 and five is 100 ft.
Answer:
y=x-1
Step-by-step explanation:
The equation is currently in standard form which is a+b=y and slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To change the form we must move the terms around using Properties of Equality.
First, subtract 1 from both sides
x-y-1=1-1
x-y-1=0
Then, add y to both sides
x-y-1+y=0+y
x-1=y
So that is the equation in slope-intercept form with a slope of 1 and a y-intercept of -1.
