Simultaneous Equations
3x + y = 4
5x - y = 22
The signs of the matching values aren't the same so we add the rest of the equations.
8x = 26
Divide both sides by 8 to get x = 3.25
Now substitute back into the first equation.
(3 x 3.25) + y = 4
9.75 + y = 4
Subtract 9.75 from both sides
y = -5.75
Answer:
502.7 meters squared
Step-by-step explanation:
The equation would be 2πrh+2πr^2. If you just plug in the radius and height you will get 502.65. Round it up and you will get 502.7.
Answer: 16,875 seats left.

Answer: 6</h3>
Explanation:
Using the rule that x = x^1, we can rewrite the p as p^1
So 11m^3n^2p is the same as 11m^3n^2p^1
The exponents are: 3, 2, 1
Those exponents add up to 3+2+1 = 6
The degree of a monomial like this is simply equal to the sum of the exponents.
