3(x-4)=5(x+2)

Answers

Answer:

x = -11

Step-by-step explanation:

1. Distribute 3 to the parenthesis and distribute 5 to the parenthesis

3x-12 = 5x + 10

2. Combine like terms (subtract 3x on both sides and then subtract 10 on both sides)

2x = -22

3. Divide both sides by 2

x = -11

please give me brainliest if this helped

Answer:

x=−11

Step-by-step explanation:

3(x-4)=5(x+2)

Simplify both sides of the equation:

3(x−4)=5(x+2)

(3)(x)+(3)(−4)=(5)(x)+(5)(2)(Distribute)

3x−12=5x+10

Subtract 5x from both sides

−2x−12=10

add 12 to both sides

−2x=22

Divide by -2 both sides

x=−11

Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year. How old are Mary and Beth?

Answers

The answer for this is 10 4

The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year.

Let 'x' be the age of Mary and 'y' be the age of Beth. Then the equations are given below.

3x + y = 34        ...1

x/2 - y = 1          ...2

From equations 1 and 2, then we have

3(2y + 2) + y = 34

6y + 6 + y = 34

7y = 34 - 6

7y = 28

y = 4

Then the value of the variable 'x' is given as,

3x + 4 = 34

3x = 30

x = 10

The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

Find the sales price for a $900 TV with a 25% discount.

If it is 25% off of the sales price we can infer that you are paying 75% of the sales cost.

To find the price you answer the equation

900•.75= 675

Therefore the total cost with the discount of 675 dollars.

The best the plastic bagger can do is segregate like products and keep from placing the eggs between the two-liter bottles of soda. Putting a plastic bag full of jars and cans down in a car trunk not designed to keep them in place is an invitation for the contents to roll away and seek out the trunks most distant corners.
