Green = g
Blue = b
Red = r
g+b = 1500
g+r = 750
g+b+r = 2000
in the 1st equation solve for b
g+b =1500
b = 1500-g
2nd equation solve for r
g+ r = 750
r = 750-g
now substitute the answers fro. b and r into the final equation.
g+b+r = 2000
g + 1500-g + 750-g = 2000
-g + 2250 = 2000
-g = -250
g = 250
So we k own the green bike is $250.
Blue = 1500- g
blue = 1500-250= $1250
red = 750-g
red = 750-250 = $500
NO!
1 yd=3 ft
36*3=108
108+2=110
114>110, therefore no
<h3>
Answer: x^2+9x+8</h3>
==============================================================
Explanation:
With many math problems, a good strategy is to break things down into smaller pieces. In this case, we need to find the area of each individual smaller rectangle
A = blue rectangle area = length*width = x*x = x^2
B = purple rectangle area = length*width = x*1 = x
C = green rectangle area = length*width = 8*x = 8x
D = orange rectangle area = length*width = 1*8 = 8
Add up A through D to get the overall area of the entire or largest rectangle possible
total area = A+B+C+D = x^2+x+8x+8 = x^2+9x+8
notice how x+8x turns into 9x. You can think of it as 1x+8x = (1+8)x = 9x
This is because x and 8x are like terms which can be combined. Everything else is left as is.
Because we don't know what number goes in place for x, we cannot simplify or evaluate x^2+9x+8 any further.
They are both multiples of 3
