Answer:

9/n-2=7

We move all terms to the left:

9/n-2-(7)=0

Domain of the equation: n!=0

n∈R

We add all the numbers together, and all the variables

9/n-9=0

We multiply all the terms by the denominator

-9*n+9=0

We add all the numbers together, and all the variables

-9n+9=0

We move all terms containing n to the left, all other terms to the right

-9n=-9

n=-9/-9

n=1

A cafeteria made 28.5 liters of lemonade. How many gallons of lemonade did the cafeteria make? (1 gallon is approximately 3.8 li
sergejj [24]

Answer:

7.5 gallons

Step-by-step explanation:

We know that 1 gal = 3.8 L, and we have 28.5 L. So, set up a proportion:

1 gal / 3.8 L = x gal / 28.5 L , where x is the number of gallons the cafeteria made

Cross-multiply:

1 * 28.5 = 3.8 * x

28.5 = 3.8x

Divide by 3.8:

x = 28.5 / 3.8 = 7.5 gallons

FH=4x+2x=6x\thinspace units

6x=18

Divide by 6 throughout the equation.

x=\frac{18}{6}=3
