You have:
x: the number of reams of white paper purchased
y:the number of reams of blue paper purchased
Then, you have the following system of equations:
x+y=10
3.50x+3.75y=36
When you solve the system shown above, you obtain:
x=6
y=4
The answer is: 6 reams of white paper
Answer:
The top left card is the one that doesn't belong because all of the others touch each other, but the top left card is parallel, and will never intersect.
Step-by-step explanation:
A = P.e^(r.t), where P is the initial population, r = rate of growth ,
t = interval of time & e = 2.7182...
A = 524(2.7182...)^(0.07x7) = 855.33 ≈ 856
Answer:
The solution is 
Step-by-step explanation:
We have the following equation:
![\sqrt[3]{5x-3} + 8 = 6](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x-3%7D%20%2B%208%20%3D%206)
We place everything with the root on one side, everything without on the other site of the equality. So:
![\sqrt[3]{5x-3} = -2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x-3%7D%20%3D%20-2)
Elevating both sides to 3, we can isolate x
![\sqrt[3]{5x-3}^{3} = (-2)^{3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5x-3%7D%5E%7B3%7D%20%3D%20%28-2%29%5E%7B3%7D)
Checking
![\sqrt[3]{5(-1) - 3)} + 8 = \sqrt[3]{-8} + 8 = -2 + 8 = 6](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B5%28-1%29%20-%203%29%7D%20%2B%208%20%3D%20%5Csqrt%5B3%5D%7B-8%7D%20%2B%208%20%3D%20-2%20%2B%208%20%3D%206)
