Answer:
x=2
y=−1
Step-by-step explanation:
You can multiply the second equation by 3:
{2x-3y=7
{9x+3y=15 add the two together (in columns):
11x+0=22
so that x=22/11=2
substitute this back into the first equation:
2*2-3y=7
y=-1
Answer:
5083662.2 ft³
Step-by-step explanation:
See picture for formula for V.
r = 46
h = 65
You can either convert the meters to ft beforehand:
65m * 3.2808 ft/m = 213.252 ft
46m * 3.2808 ft/m = 150.9168 ft
Or calculate in meters and multiply by 3.2808³ afterwards.
Since you never plan to buy the popcorn but only the movie
ticket, therefore we can definitely say that there is a direct correlation
between the total price and the number of tickets bought.
The proportion equation is:
P = 10.50 t
<span>where P is the total price and t is the number of tickets</span>
59-7=52
52÷2=26
