Answer:
C
Step-by-step explanation:
You can write the equation like this:
A - 2.5 = 1.5
If you reverse the equation, it looks like this:
1.5 - 2.5 = A
1.5 - 2.5 = 4
A = 4
Answer:

To solve for slope here is an equation, to help: 
Answer:
D. is the answer
Step-by-step explanation:
the side lengths always have to be equal so 6+8 = 10 and 10 is equal to 10
that means it makes a right triangle
Answer:
182 children, 91 adults, 60 students
Step-by-step explanation:
The quantity of adults is x, then the quantity of children are 2x, the quantity of students is 333-x-2x=333-3x. The charge from all adults is 12x, students gave 7*(333-3x), children gave 5*2x=10x, the sum of all money is 2422
12x+ 7(333-3x)+10x=2422
12x+2331-21x+10x=2422
2331+x=2422
x=91- the amount of adults
1) 91*2=182- the amount of children
333-91-182= 60- the amount of students
