Answer:
School A sent 55 kids, School B sent 110 kids, & School C sent 52 kids.
Step-by-step explanation:
A = x kids
B = 2x kids
C = x-3 kids
Each kid pays $10, so multiply 10 by the amount of students from each school.
$2170 was payed in total.
So,
2170 = 10(x) + 10(2x) + 10(x-3)
Un-distribute the 10...
2170 = 10 (x + 2x + x - 3)
Divide both sides by 10...
217 = x + 2x + x - 3
Add 3...
220 = x + 2x + x
Combine like terms...
220 = 4x
Divide by 4...
x = 55
Go back to your original equations... plug in 55 for x.
A = (55) kids
B = 2(55) kids
C = (55)-3 kids
Hope this helped. :)

Whats the slope of the line?
Answer:
m = rise/run = 4/5.
Step-by-step explanation:
This line goes throught the "exact" grid intersections (-2, 0) and (3, 4). As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise'). Thus, the slope of this line is m = rise/run = 4/5.
solve to find x 3/4 (5x-3) + 8 = 17
Answer:
3
Step-by-step explanation:
3/4 (5x -3)+8=17
3/4 (5x -3) = 17 - 8 = 9
(5x -3) = 9 * (4/3)= 36/3 = 12
5x = 12 + 3 = 15
x = 3

What must be true of the side lengths in order to build a triangle with only two angles the same size?
Answer:
A triangle with two angles of the same size is an isosceles triangle. So two of its sides are going to have the same measure and the third different. The length of the sides will depend on the height of the measure of the given angles.
Step-by-step explanation:
Isosceles triangles can be classified into an isosceles right triangle, isosceles obtuse, isosceles acute depending on the measurements of its internal angles.
find the circumfernce of the circle Use 3.14 for
Answer: To find the circumference of a circle, use the formula, 2(3.14)(r) (r is the radius, and if it gives the diameter, divide the diameter by 2 [to get the radius]). To find the actual circumference of the circle, multiply 2 and 3.14, becoming 6.28. Then, multiply 6.28 by whatever the radius is. Hope you find this useful!
Note: I am going based on no given picture and measurements of the circle, the other person that answered is, also, correct, and you could multiply the first two numbers (and then multiply the other number by the answer you received) OR multiply the first number, being 2, by the radius (and multiply that answer by the number of 3.14). For an example, the radius=10 units. You could either do 2x10=20, then 20x3.14=62.8 units^2 or multiply 3.14x2=6.28 units, then multiply 6.28 by 10, which is 62.8 units^2.

use Multistep Pythagorean Theorem to answer
Answer:
√5
Step-by-step explanation:
I think that is the answer I never come to such a question of changing things to radical form but I guess 5 cannot be multiplied by a number such that it has a square root so the answer is that√5

If students get their assignments done on time there is an 80% chance of earning a good grade in the class. If the assignments are finished during class or late then there is only a 30% chance of earning a good grade in the class. If the assignments are not done at all then there is only a 5% chance of earning a good grade in the class. In a certain class, 50% of the students have the assignments completed on time, 40% finish during class, and 10% do not do their assignments. If a student from this class is selected at random, what is the probability that student has a good grade?
Answer:
Probability that student has a good grade = 0.525
Step-by-step explanation:
Given
Chances of earning a good grade when assignments are done on time = 0.80
Chances of earning a good grade when assignments are finished during class or late = 0.30
Chances of earning a good grade when assignments are not done at all = 0.05
% of students who completed assignment on time = 0.50
% of students who completed assignment during class = 0.40
% of students who did not completed assignment at all = 0.10
Probability that student has a good grade
= (0.80 *0.50) + (0.30*0.40) + (0.05*0.10)
= 0.525
