Answer:
5 hours
Step-by-step explanation:
Mark recieves 3mg per hour. This can be rewritten as y=3x. Cassie recieves 2x+5. To solve, use substitiution. 3x=2x+5. To solve, subtract "2x" from "3x." You then get x=5.
Answer:
A certain shade of pink us created by adding 3 cups of red paint to 7 cups of white paint
Step-by-step explanation:
Constant of proportionality is the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality.
To make color pink,
for every 3 cups of red , we need 7 cups of white.
Let 'r' be the cups of red required
let 'w' be the cups of white required
so , as per the question
for 3 r we need = 7 w
r = 7/3 w
so, 7/3 is constant of proportionality
X^2= (x-2[root of x])(x+2[root of x])
Answer:
−3b−6x+2
Step-by-step explanation:
2x+4−7−3b+5−8x
=2x+4+−7+−3b+5+−8x
Combine Like Terms:
=2x+4+−7+−3b+5+−8x
=(−3b)+(2x+−8x)+(4+−7+5)
=−3b+−6x+2
