Please help me, i will mark brainliest The seventh grade class is putting on a talent show to raise money for a class trip. It costs $500 to rent the banquet hall they are planning on using. If they charge $15 per ticket, how many tickets do they need to sell in order to raise at least $1000?
Part A
The variable in this problem will represent the number of:
A- students
B- tickets
C- parents
D- money
Part B
​Choose the correct inequality to represent the story problem:
A- 15x+500=1000
B- 15x-500≥1000
C- 15x+1000≥500
D- 15x-500≤1000
​ Part C
How many tickets do they need to sell? (Write your answer as an inequality)

B-Tickets

B-15x-500≥1000

C-x≥100

Step-by-step explanation:

X is the variable because you need to find how many tickets need to be sold

The answer is B  because they need to raise $1000 or more

15x-500≥1000 (add 500 to both sides)

15x≥1500

x≥100

a is the correct

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
