Answer:
x = 18 (verified by algebra) ✅Step-by-step explanation:
When we have two similar triangles, we can use a proportion to determine an unknown value.
[tex]\frac{2x + 80}{87} = \frac{80}{60}[/tex]
We will cross multiply to get two equivalent equations that can be solved.
(2x + 80) x 60 = 120x + 4800
We can simplify this by dividing both sides by 24 to get a much simpler equation to work with: 5x + 200.
80 x 87 = 6960
We will also divide this by 24. The answer is 290
5x + 200 = 290
Subtract 200
5x = 90
Divide by 5
x = 18
Now, we can also check to make sure we did everything correctly.
(2(18) + 80) x 60 = 120x + 4800
(36 + 80) x 60 = 120(18) + 4800
116 x 60 = 2160 + 4800
6960 = 6960 ✅

Heidi's friends want to reserve a karaoke studio this weekend. It cost $30 to reserve a room, plus $5 per person for pizza, plus $2 per person for a soda. How many people can be in the group if the total cost is $65 please this is the last 2 questions I have
Answers
Answer:
5
Step-by-step explanation
2 + 5 is 7 which equals 1 person 7 x 5 = 35 which means their will be 5 people per group because 30 {room cost} plus 35 is 65
what do i mean?
2 + 5 IS 1 person and 2 plus 5 is 7 so the remaining money they have would be 35 because 65 minus 30 is 35 so i divid 35 by 7 which brings 5 people

Answers
Answer:
35 mph
Step-by-step explanation:
The answer should be the average speed it takes to drive, so you would find the average of the speed to go to A with the speed to go to B. You already have the two answers for part A and B, so you would add them, then divide them by 2. It would look like this:
[tex]\frac{30+40}{2} =\frac{70}{2} =35[/tex]
So it would be 35 mph

Can someone help me with systems of equations, (graphically)
Answers
Answer:
Step-by-step explanation:
You would use -6 and 7 to start your line. With the equation “y=5/6x+7", you would put a dot on 7. Then you would use the 5/6 to start making your line. With fractions, it's always rise/run. Starting from 7, you go up 5 then over(right) 6 until you run out of room on the graph. Then you do the opposite, down 5 then back(left) 6. Then you should have your first line. Then repeat that for the next equation. Start at -6, go down 4 and back three until you run out of room on the graph, then do the opposite. Go up 4 and over 3.
