Answer:
C
Step-by-step explanation:
Any value of x makes the equation true.
B=blue
g=green
r=red
2 times as many blue as green
b=2g
3 times as many red as blue
r=3b
subsitute 2g for b
r=3(2g)=6g
r=6g
r+g+b=765
so we subsitute
r=6g
g=g
b=2g
6g+g+2g=765
add like terms
9g=765
divide both sides by 9
g=85
subsitute
b=2b
b=2(85)
b=170
170 blue
Answer:
Step-by-step explanation:
Given the following quadratic equation:
The steps to solve it are:
1. Move the terms to one side of the equation:
2. Apply the Quadratic formula 
.
In this case we can identify that:
Then, substituting these values into the Quadratic formula we get the following solutions:
Answer:
a.3
Step-by-step explanation:
2:x and 12:18
We need to get from 2 to 12 and 3 to 18
2* something = 12 x* something = 18
Divide by 2
something =12/2
something =6
x*6 = 18
x = 18/6
x=3
