Answer:
We need to find a relationship between the equations.
Let's solve for one variable.
2x + 2y = 15
2y = 15 - 2x
We know what 2y is in relation to x. Now we can solve.
2x + 15-2x = 15
15 = 15
Unless there are more equations, this is your answer. For it to be simultaneous you need more than one equation.
Hey there! :)
The formula for finding volume of a cone = (π · r² · h) ÷ 3
r = 3
3² = 3 × 3 = 9
h = 7
7 × 3 × π = 21π
Your answer is C. 21π³
Hope this helps :)
Answer:
-5x<60 divide both side by -5
x>-12
2/5 is greater than 1/3, because 2/5 = .4 and 1/3= .33333333..... Hope I was helpful.
