Part A. 250+45a=t
That's because 'a' is the variable in which we don't know how many appointments she will have. 'a' times the $45 would be in the equation. Then you would have to add the $250 for the tests and medicines.So 250+45a=t
Part B.(250+45a)-(25%*t).
That's because the first set in parentheses is the total cost. You would have to subtract that buy the discount times the total cost which represents the the second set of the equation.:)
Part C.25%*6 appointments equals 1.5. You have to solve (250+45) and then multiply 25%*6.That product plus (250+45) would be your final answer.U won't tell you the answer because it would help.U would need explanation.This is how I would answer the question.Hope this helped
The area of the circle is 6,358.5cm²
<h3>Area of the circle</h3>
The formula for calculating the area of a circle is expressed as;
r is the radius = x + y
r = 25 + 20 = 45cm
Substitute the given parameters into the formula to have:
A = 3.14(45)²
A = 6,358.5cm²
Hence the area of the circle is 6,358.5cm²

Answer:
It is called this
Step-by-step explanation:
Since the three points are all on the same line, they are called collinear points.
Answer:28
Step-by-step explanation:
10%= 8
35%/10%= 3.5
8 x 3.5 = 28
Answer:
y = 2/3x + 6
Step-by-step explanation:
If two lines are parallel, that means their slopes are the same.
Rewrite 2x - 3y = 15 to y = 2/3x - 5
The slope is 2/3, so the answer should have a slope of 2/3 as well.
The equation is now y = 2/3x + b
To find b, substitute (-3,4)
y = 2/3x + b
4 = 2/3(-3) + b
4 = -2 + b
6 = b
So the equation is y = 2/3x + 6
