3(4x+6)=x-4

Pls look at the picture for the rest of the question thanks!

Answers

Answer:

(x = −2) sentence below

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(4x+6)=x−4

(3)(4x)+(3)(6)=x+−4(Distribute)

12x+18=x+−4

12x+18=x−4

Step 2: Subtract x from both sides.

12x+18−x=x−4−x

11x+18=−4

Step 3: Subtract 18 from both sides.

11x+18−18=−4−18

11x=−22

Step 4: Divide both sides by 11.

11x

11

=

−22

11

x = −2

I used distributive property because it allows me to simply the equation when dealing with the unknown value of x.

Remark

The two angles share the same side of vertically opposite angles. That makes them supplementary which means the two angles add to 180 degrees.

Equation

4x + 8x + 12 = 180         Combine like terms on the left

Solution

12x + 12 = 180                Subtract 12 from both sides12x = 180 - 12                 Combine12x = 168                        Divide by 12x = 168/12x = 14

Answer:

x = $11

Step-by-step explanation:

5x = $55

9x = $99

2x = $22

In order to find the relationship between x and y, all we have to do is divide y by the term.

                                                       $55 ÷ 5 = 11

                                                       $99 ÷ 9 = 11

                                                       $22 ÷ 2 = 11

                             Therefore, each ticket sold is $11, or x = $11

Evan and Dorinda make bracelets for a craft fair. Evan makes 10 bracelets the first day and 8 bracelets each day after that. Dorinda makes 8 bracelets the first day and 8 bracelets each day after that. If they make bracelets for 6 days, how many bracelets will they make in all? a. 567 b. 987653 c. 8765 d.65

Answers

Answer:

98 bracelets

Step-by-step explanation:

Number of days, n = 6

Evan:

= 10 + 8(n - 1)

= 10 + 8(6 - 1)

= 10 + 8(5)

= 10 + 40

= 50 bracelets

Dorinda

= 8n

= 8(6)

= 48 bracelets

Total bracelets they will make in all = Evan + Dorinda

= 50 + 48

= 98 bracelets

Solve for t. You must write your answer in fully simplified form.

−19=7t

Answers

Answer:

t=-19/7

Step-by-step explanation:

you need to isolate for t which means you need to get t all alone on one side of the equation. Do do that you can divide both sides by 7. This gives you -19/7=7t/7

we know that anything divided by itself is 1 so we get -19/7=t

This is the simplest for because 19 and 7 are both prime numbers, so you can't simplify them.

t = -19/7

The goal is to get t by itself. To do that you have to divide both sides by 7. The right side’s 7 will cancel.

-19/7 is the simplified form because -19 cannot by divided by 7 in the sense that the answer will be a whole number (it’ll be a decimal or an improper fraction, etc).
