How to convert 18 gallons/1 hour to cups and minutes
Ne4ueva [31]
So there are 2 things you need to convert, the first is the gallons to cups and the second is the hours to minutes. so I like to set it up with numerators and denominators and then multiply the ratios. All same terms will cross out and be opposite of each other. 

(18 gal/1 hour) x (1 hour / 60 minutes), now we have (0.3 gallons/1 minute) we just have to change gallons to cups

(0.3 gallons/ 1 minute) x (4 quarts/1 gallon) x (2 pints/1 quart) x (2 cups/1 pint)

this comes out 4.8 cups/1 minute

Write the slope intercept equation for a line with the given points m=3/8, passes through (4,5)
natta225 [31]

Answer:

The answer is: y = 3/8x + 28/8

Step-by-step explanation:

Given point: (4, 5)

Given slope m = 3/8

Uset the point slope form:

y - y1 = m(x - x1)

y - 5 = 3/8(x - 4)

y - 5 = 3/8x - 12/8

y = 3/8x - 12/8 + 5

y = 3/8x - 12/8 + 40/8

y = 3/8x + 28/8

Proof, use point (4, 5):

f(x) = 3/8x + 28/8

f(4) = 3/8(4) + 28/8

= 12/8 + 28/8

=40/8 = 5, giving (4, 5)
