Here is a balanced hanger diagram in which a circle has a mass of 3 grams and a square has a mass of 2 grams.
Which equations could represent the diagram, assuming t represents the triangles?
3c + 2s + 2t = 3c + 2s + 5t
2t + 21 = 5t + 12
3(3) + 6(2) + 2t = 2(3) + 3(2) + 5t
2t + 9 = 5t + 5
5t + 6 + 6 = 9 + 12 + 2t

Grace opens a lemonade stand in her neighborhood to earn money. For each cup of lemonade she sells, Grace earns $0.50 profit. Considering that it cost her $6 in start-up costs, Grace graphed her potential profits, where x represents the number of cups of lemonade she sells and y represents the amount of profit earned in dollars. However, Grace made a mistake with her graph. Her y-intercept was incorrectly drawn. At what value should the graph have crossed the y-axis?

Given that the point (9,7) is on the graph of y=f(x), there is one point that must be on the graph of 2y=(f(2x)/2) + 2. What is the sum of coordinates of that point?
Answer:
Step-by-step explanation:
jjjjj
The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function
The sum of the coordinates of the point is 7.25
The reason the above values are correct is as follows;
The given parameter is;
The point (9, 7) is on the graph y = f(x)
Required:
A point on the graph, 2·y = (f(2·x)/2) + 2
Solution:
Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;
f(2·x) = f(2 × 9/2) = f(9) = 7
Therefore;
2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5
y = 5.5/2 = 2.75
y = 2.75
The coordinate of the point is (x, y) = (2.75, 9/2)
The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

3(x-4)=5(x+2)
Answer:
x = -11
Step-by-step explanation:
1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis
3x-12 = 5x + 10
2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)
2x = -22
3. Divide both sides by 2
x = -11
please give me brainliest if this helped
Answer:
x=−11
Step-by-step explanation:
3(x-4)=5(x+2)
Simplify both sides of the equation:
3(x−4)=5(x+2)
(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)
3x−12=5x+10
Subtract 5x from both sides
−2x−12=10
add 12 to both sides
−2x=22
Divide by -2 both sides
x=−11

Lars did some research on how much it would cost him to buy a gym membership.
At Murfield Country Club, a membership costs $20. Every time Lars goes to the gym he must pay an additional $30/hour.
At Pete’s Gym, it would cost Lars $80 for 2 hours and $120 for 3 hours.
a) Which of the two companies charges no initial fee? How do you know?
b) What is the slope of each line? (Murfield Country Club and Pete's Gym).
Slope for Murfield Country Club =
Slope for Pete’s Gym =
c) Write the equation for each line. (Murfield Country Club and Pete's Gym).
Equation for Murfield Country Club =
Equation for Pete’s Gym =
Answer:
A. it would be Pete's gym because he doesn't have to pay for a membership as well as paying $30 per hour he only has to pay for the hourly cost.
B. Lars-starts at 20 then goes to 50 then 80 ect... goes up by 30 starting at 20 because of the membership he payed.
Pete's- starts at 0 then to 40, 80, 120, 160 ect... goes up by 40 starting at zero.

A school allots £1500 to spend on a trip to the theatre.
Theatre tickets have a regular cost of £25 each and are on offer for 1/5 off.
A train ticket for the day will cost £15 each.
If 2 teachers and the maximum number of students attend, how many students go on the trip?
Answer:
40 students
Step-by-step explanation:
If the tickets are 1/5 that means they cost 4/5
25 * 4/5 = 20
The tickets cost 20 and the train costs 15 so the total per person is 35
Teachers: 2 at 35 = 70
1500 -70 = 1430
Take 1430 / 35 =40.85714286
We can send 40 students
Answer:
40
Step-by-step explanation:
since the school allots £1500 to spend on a trip to the theatre. Theatre tickets have a regular cost of £35 each and are on offer for 1/5 off
therefore 4/5*35 = 28 for the tickets
:
A train ticket for the day will cost £15 each.
therefore total cost for each: 28 + 15 = 43 pounds each
:
If 2 teachers and the maximum number of students attend, how much money will the school have left over?
:
let s = no. of students
43(s+2) =< 1500
43s + 86 =< 1500
43s =< 1500 - 86
43s =< 1414
s =< 1414/43
s =< 32.88, 32 students max
:
find how much left over. plus 2 teachers = 34 people
1500 - 43(34) =
1500 - 1462 = 38 pounds left over
