X+3 or x-8
These answers will both work!
Answer:
x is 13
y is 39
Step-by-step explanation:
Answer:
13
Step-by-step explanation:
3h - j
3(8) - 11
24 - 11
13
The hotel is $250 plus $25 per person so the equation would be
y= 25x + 250
(Y is the total cost and x is the number of people)
the restaurant is $100 plus $40 per person so the equation would be
y = 40x + 100
What we want to know is which x value would make the y values equal to each other. So you can just replace the "y" in one equation with the other equation:
25x + 250 = 40x + 100
and then solve...
1. subtract 100 from both sides
25x + 150 = 40x
2. subtract 25x from both sides
150 = 15 x
3. divide both sides by 15
10 = x
you can check by plugging 10 into the original equations
25(10) + 250
250 + 250 = 500
and
40(10) + 100
400 + 100 = 500
they both cost $500 when you invite 10 people
The answer is k= 2.5
Explanation: Rotating the shape will show that one side is 20:8. Divide these together and you get 2.5.
