Answer:
i hope its correct
Step-by-step explanation:
11x + 2y=68 ------------1
5x+y=13 ------------2
y= 13-5x. ------------3
put 3 into 1
11x +2(13-5x) =68
11x +26 -10x =68
x=42
put x =42 into 2
5(42) +y =13
210+y=13
y=13-210
y=197
Answer:
, x = $6
Step-by-step explanation:
The expression 
to represent the store's weekly profit in dollars, where x represents the price of a new video game.
Let 
We need to rewrite this quadratic function in the vertex form.
The equivalent expression that reveals the video game price that produces the highest weekly profit is
and the price is $6
Answer:
-15
Step-by-step explanation:
6.8(6.7 – 7.2) – 2(4.6 + 1.2)
The first step in PEMDAS is to do whatever's in the parenthesis. So, this would be the 6.8 bit.
6.8 times 6.7 is 45.56 and then 6.8 times 7.2 which is 48,96
Now we can also do the second set of parenthesis. 2 times 4.6 is 9.2, and 2 times 1.2 is 2.4
The equation now reads- (45.56 - 48.96) - (9.2 + 2.4)
All we have to do is evaluate what's in the parenthesis, the first set equals -3.4 and the second set equals 11.6
So, now our expression reads, -3.4 minus 11.6 which equals -15
Answer:
Your answer would be the 60th
Step-by-step explanation:
This is your solution due to the fact that when you find the multiples of 12 and 30 you will realize that that's the first number they meet at, let me show you.
Multiples of 12 - 12, 24, 36, 48, 60
Multiples of 30 - 30, 60, 90, 120, 150
So The Least Common Denominator is 60!
Thus that is how I know that the 60th customer at the movie theater would get both items for free.

Answer:
1 = 0.61, 2 = 1.13
Step-by-step explanation:
The first is 25 + 25 + 10 + 1. This is 61 cents which is 0.61 of 1 dollar. The second is 100 + 10 + 1 + 1 + 1. This is equal to 113, 0r 1.13
