2. Cheryl had $900 initially
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.
The unit price is tantamount to saying the price of each. For this item, we are asked to determine the price of each can. Thus, it can be determined by dividing the price to number of cans.
$5.25 / 5 = 1.05
Thus, each can of tomato sauce costs $1.05.
Answer:
-18 is the ans you can calculate it
Answer:
4.8125 or 4 13/16
Step-by-step explanation:
(11 10/16 - 2 1/16) - 4 12/16
(9 9/16) - 4 12/16
4 .8125 or 4 13/16
