Solve each equation for the indicated variable 22. 12(m+3x)=18(x-3m);m

12(m+3x)=18(x-3m)

By the distributive property,

12m+36x=18x-54m

Since we want to solve for m let's bring it to one side and move everything else to the opposite side.

12m+54m=18x-36x

Now we simplfy.

66m=-18x

Divide both sides by 66,

m=-\frac{18x}{66}

In simpliset form,

m=-\frac{3x}{11}

Elena L [17]

Answer:

0.35 Gallons.

| 7x-2 | +3 = -1 solve for x
seropon [69]

Answer:

x = -2/7 or

x = 6/7

Step-by-step explanation:

|7x-2| + 3 = -1  subtract 3 from both sides

|7x-2| = -4 now there are two probabilities

7x-2 = -4 or

7x-2 = 4 if first probability the value of x would be:

7x-2 = -4 add 2 to both sides

7x = -2 divide both sides by 7

x = -2/7 for the second probability the value of x would be:

7x-2 = 4 add 2 to both sides

7x = 6 divide both sides by 7

x = 6/7

RU and JM are diagonals. Given ST= 6, KL = 10, and RU= 12, find JM
AfilCa [17]

Your question is incomplete. The complete question is attached down

Answer:

JM = 20 units

Step-by-step explanation:

∵ Hexagon RSTUVW is similar to hexagon  JKLMNP

∴ The corresponding sides and diagonals have a constant ratio

∴ \frac{RS}{JK}=\frac{ST}{KL}=\frac{TU}{LM}=\frac{UV}{MN}=\frac{VW}{NP}=\frac{RW}{JP}=\frac{RU}{JM}

∵ ST = 6 units

∵ KL = 10

∴ \frac{ST}{KL}=\frac{6}{10}

- Simplify it by dividing up and down by 2

∴ \frac{ST}{KL}=\frac{3}{5}

∵ \frac{ST}{KL}=\frac{UR}{JM}

∵ RU = 12 units

∴  \frac{3}{5}=\frac{12}{JM}

- By using cross multiplication

∴ JM × 3 = 5 × 12

∴ 3 JM = 60

- Divide both sides by 3

∴ JM = 20 units
