240 total
We know-
150=62.5
x = 100
Cross multiply
15,000=62.5x
/62.5 = /62.5
240 = x

Can someone please put 1 1/4 cups 0.4 L 950 mL and 0.7 gallons in greatest to least
Yuliya22 [10]

Answer:

0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups

Step-by-step explanation:

First we need to convert the information given into one unit, in this case I will convert it into liters (L)

CUPS

1 cup is equal to 236.588 ml and is the same as .236 L using this information and knowing that 1 1/4 cup is the same as 1.25 cups we have that

x=\frac{1.25\times .236}{1}

x=.295 L

LITERS

0.4 L will stay the same

MILILITERS

1 liter is 1000 ml so 950 ml is the same as

x=\frac{950 \times 1}{1000}

x=.950 L

GALLONS

1 gallon is 3.78541 L so 0.7 gallons are

x=\frac{0.7 \times 3.785}{1}

x=2.649 L

arranging the data from greatest to least we have that 0.7 gallons, 950 mL, 0.4 L, 1 1/4 cups

Can someone tell me how to figure this question out?
valkas [14]

y = 3x - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here slope m = 3

y = 3x + c ← is the partial equation

to find c substitute (- 2, - 7 ) into the partial equation

- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1

y = 3x - 1 ← equation in slope- intercept form

I need the answer immediately!!!!!!!!
sergiy2304 [10]

Answer:y=-5x-2

Step-by-step explanation:

This will have a negative slope since the line goes from left to right. Use rise over run to find the slope of -5 and look at the y axis where it intersects to get -2

Have a great day!
