4x = 9 - 3y
4x = -3y + 9
x = (-3y + 9) / 4
Answer:
Step-by-step explanation:Simplifying
3x + 8 = 2x + -21
Reorder the terms:
8 + 3x = 2x + -21
Reorder the terms:
8 + 3x = -21 + 2x
Solving
8 + 3x = -21 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
8 + 3x + -2x = -21 + 2x + -2x
Combine like terms: 3x + -2x = 1x
8 + 1x = -21 + 2x + -2x
Combine like terms: 2x + -2x = 0
8 + 1x = -21 + 0
8 + 1x = -21
Add '-8' to each side of the equation.
8 + -8 + 1x = -21 + -8
Combine like terms: 8 + -8 = 0
0 + 1x = -21 + -8
1x = -21 + -8
Combine like terms: -21 + -8 = -29
1x = -29
Divide each side by '1'.
x = -29
Simplifying
x = -29
Answer:
17.325 liters
Step-by-step explanation:
Number of Apollo Spas Services= 105 hot tubs
Each hot tub needs Muriatic acid= 165 ml
We have to find the total liters of muriatic acid
Total number of liters required = Number of hots cups× 165 ml
Total number of liters required= 105×165 ml
Total number of liters required= 17,325 ml
1ml = 1/1000 liters
Total number of liters required= 17.325 liters
Hence, the correct answer is 17.325 liters
Answer:
I two groups are formed: 18 students
If 3 groups are formed: 12 students
Step-by-step explanation:
We will answer this problem based on two occurrences:
<em>1. The students chose to form only two groups:</em>
If the students chose to form only two groups, the number of students in each group will be got by dividing the total number of students by 2. this will be 36/2 = 18. Therefore, there will be 18 students per group if only 2 groups were formed.
<em>2. The students chose to form three groups:</em>
If the students chose to form three groups, we will divide the total number of students by 3. this will be 36/3 = 12. Therefore, there will be 12 students per group if only 3 groups were formed.
