Answer:
11
Step-by-step explanation:
56.50-7=49.50
49.50divided by 4.50=11
Only one because there is one variable and the combined coefficients of x are non-zero.
(0.75(x+40)=0.70(x+20), 0.05x=14-30=-16, x=-320)
Answer:
2x-3y=-15
Step-by-step explanation:
y=2/3x+5 and write in standard form.
and you come up with 2x-3y=-15.
Divide the diameter by 2 to get the radius and then plug into cone volume pi*r^2*h/3 which is a bit under 160 so the answer is A
