Snowboarding cautiously down a steep slope at a speed of 7.0 m/s, Sarah, whose mass is 50.0-kilograms, is
afraid she won't have enough speed to travel up a slight uphill grade ahead of her. She extends her hand, as
her friend Trevor, having a mass of 100.0-kilograms is about to pass her traveling at 16 m/s. If Trevor
grabs her hand, calculate the speed at which the friends will be sliding.

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

step-by-step explanation:

i'm not sure how to show the work for this

answer : c and d or 4(29 + 6)

4(29) + 4(6)
