X=36
you add 126 to 162 making it 288, then you minus 5 out of 13 making it 8. 288/8 =36
Answer:
Megan will have to pay $2, 260 for surgery.
Step-by-step explanation:
1. Translate percent into decimal:
90% -> 0.9
2. Multiply (to find out how much the insurance company pays):
(0.9)(14, 600) = 13, 140
3. Subtract:
14, 600 - 13, 140 = 1, 460
4. Add (to find out how much Megan pays):
1, 460 + 800 = 2, 260
13.63 * 38 = 517.94
671.28 - 517.94 = 153.88
153.88 : 13.63 = 11.25 the number of hours she overworked
Answer:

Step-by-step explanation:
Perimeter is all sides added together.
13 + 14 + 7 + 18 = 52
Answer:
There were 26 students in his class and the teacher had 83 ml of the solution.
Step-by-step explanation:
Mr. Kohl has a "x" amount of solution, if he divides it by the number of students "n" he'll give each student 3 milliliters and have a left over of 5 milliliters. If the amount of solution Mr. Kohl had was "x + 21" then he'd be able to give each student 4 milliliters of the solution. From these informations we have:
x = 3*n + 5
(x + 21)/n = 4
x + 21 = 4*n
x = 4*n - 21
Now that we have two equations and two variables we can solve the system of equations, as seen bellow:
3*n + 5 = 4*n - 21
3*n - 4*n = -21 - 5
-n = -26
n = 26
x = 4*26 - 21 = 83 ml
There were 26 students in his class and the teacher had 83 ml of the solution.
