By knowing that there are four cups in one quart, one can infer that there are 80 cups in 20 quarts.

Know that there is 2 pints in a quart and 2 cups per pint so, 20x2=40x2=80.

Answer:

Step-by-step explanation:

slopes and equations:

find the  equation thur ( 6,1 )  and (-2,-3)

find the slope m

m = (y2-y1) / (x2-x1 )

m = (-3 - 1) / (-2 -6)

m = -4 / -8

m = 1/2

now use the point-slope formula with our known slope

y-y1 = m(x-x1)

y-1 = 1/2(x-6)

y - 1 = 1/2x -3

y = 1/2x -3 +1

y = \frac{1}{2}x -2

Find the equation parallel to y = 3x + 6 and thur (0,1)

Parallel means the same slope, the slope is 3 for the equation above.

use the slope-intercept formula again with the point given and the slope 3

y-1 = 3(x -0)

y - 1 = 3x

y = 3x +1

Find the equations perpendicular to 2x + y = 8 and the same y intercept as  4y = x + 3.

put both equations into proper form

y = -2x +6

y = \frac{1}{4}x + \frac{3}{4}

perpendicular means  reciprocal slope and change the sign, the 2nd equation has an intercept of  \frac{3}{4} , so

y = 1/2x + \frac{3}{4}

there you go Amanda  :)

Answer:

first you would add 5 on both sides

then you should have 15y = 28

then you will divide 15 by 15

then do the same to 28

When is written in simplest radical form, which value remains under the radical?
Semenov [28]

Answer:

The number that is a perfect square remains on the outside and the one that isn't, stays on the inside. For example, you can make the number 2\sqrt{3} only when the number on the outside is a perfect square. The original number was 4, so it reduced down to 2, and the other number stayed in the radical
