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.
Answer: −36x+34
Step-by-step explanation:
Equation: −2+6(−6x+6)
Step 1. distribute the equation:
−2+(6)(−6x)+(6)(6)
−2+−36x+36
Step 2. Finally combine like terms:
−2+−36x+36
(−36x)+(−2+36)
−36x+34
Final Answer:
−36x+34
Hope I could help! :)
Find the horizontal and vertical distance between the points. First, subtract y2 - y1 to find the vertical distance. Then, subtract x2 - x1 to find the horizontal distance.
Answer:
A and C
Step-by-step explanation:
A: 5 tens = 50
9 tenths = 0.9
6 hundreths = 0.06
= 50.96
C: 5*10 = 50 + 9 * 1/10 = 0.9 + 6 * 1/100 = 50.96
