Answer:
5 1/8 pizza
Step-by-step explanation:
3/4=6/8
1/2=4/8
7/8=7/8
3
6/8+4/8+7/8=17/8= 2 1/8 pizza
3+2 1/8= 5 1/8
Answer:
x( x-8)(x+8)
Step-by-step explanation:
x^3 - 64x
Factor out an x
x( x^2 -64)
This is the difference of squares x^2 -8^2 which is a^2 - b^2 = (a-b)(a+b)
x( x-8)(x+8)
-27 can be rewritten as -3 * -3 * -3
So the 3rd root of -27 is -3.
(You can check on the calculator to make sure as well)
I think it means that you should divide 1820 and 40, and then the answer is what h would be.
Answer:
r = cost of rollercoaster = 6
f = cost of ferris wheel=4
g = cost of graviton=8
Step-by-step explanation:
r = cost of rollercoaster
f = cost of ferris wheel
g = cost of graviton
r+f = 10
g+f = 12
r+g = 14
Take the third equation and subtract the first equation
r+g =14
-r-f = -10
-------------------
g-f = 4
Take this and add it to the second equation
g-f = 4
g+f = 12
-------------------
2g = 16
Divide by 2
g = 8
Now find f
g+f = 12
8+f = 12
f = 12-8
f=4
Now find r
r+g =14
r+8 =14
r = 14-8
r = 6
