Answer:
7.5
Step-by-step explanation:
let x be the ticket and y the popcorn
x+y=15
x+3y=30
solve for x and y using simultaneous equations
x=7.5
y=7.5
Answer: Yes, it is a solution
===================================================
Explanation:
Any ordered pair, aka point, is of the form (x,y)
x is always listed first
The point (0,-2) means x = 0 and y = -2 pair up together
Let's plug them into the equation and simplify everything
x-2y = 4
0-2(-2) = 4
0+4 = 4
4 = 4
We end up with a true statement since we get the same thing on both sides, therefore the original equation is true for (x,y) = (0,-2)
(0,-2) is a solution to the given equation
Phrased another way: the point (0,-2) is on the line x-2y = 4. This point is the y intercept.
Answer: Malik's total profit is $213
Step-by-step explanation:
2 * 45 = 90
2 * 65 = 130
130 - 90 = 40
3 * 85 = 255
3 * 126 = 378
378 - 255 = 123
5 * 5 = 25
5 * 15 = 75
75 - 15 = 50
50 + 40 + 123 = 213
Answer:
1. C 2. D
Step-by-step explanation:
First is to divide 5/9 which equals 0.555
then rounding that to the nearest tenth would be 0.56
because you would use the rule, "5 and up round up, 4 and down round down"
Hope this helped!!
