__________________

We have a dilemma here, there is a variable and constant numbers in this equation. No fear, this is when like terms comes into play, where you can only combine two numbers that have the same ending, whether it be variables, exponents, e.t.c.

Distribute :

4 + 16 - 12(1 + 2x)

4 + 16 - (12(1) + 12(2x))

4 + 16 - 12 + 24x

Use PEMDAS (Add left to right) :

4 + 16 - 12 + 24x

20 - 12 + 24x

8 + 24x

24x + 8

Answer 2

8-24x is your answer

Step-by-step explanation:

4+16-12(1+2x)

20-12-24x

8-24x

A store sold 7 white chairs for $148.75. How much 10 white chairs cost at the same unit price?

Answers

Answer:

212.5

Step-by-step explanation:

7 chairs = 148.75

148.75 ÷ 7 = 21.25

21.25 x 3 = 63.75

148.75 + 63.75 = 212.5

Given that 3x – 8y = 39
Find y when x = 3
Give your answer as an improper fraction in its simplest form.​

Answers

Answer:

- [tex]\frac{15}{4}[/tex]

Step-by-step explanation:

Given

3x - 8y = 39 ← substitute x = 3 into the equation

3(3) - 8y = 39

9 - 8y = 39 ( subtract 9 from both sides )

- 8y = 30 ( divide both sides by - 8 )

y = [tex]\frac{30}{-8}[/tex] = - [tex]\frac{15}{4}[/tex]

Find the missing section. Answers must be in fraction form.

Answers

Answer:

[tex]\frac{1}{10}[/tex]

Step-by-step explanation:

We have a circle that is split in three sections, two of which we know and we are asked to find the third missing section.

For the circle, we know that 4/5 and 1/10 is fit. Now we need the last one, to solve, we need to get the same denominator and see how much is missing.

Since 1/10 is our highest denominator, let's change 4/5 to have 10 as a denominator. Which would be through multiplying 5 to get 10.

What times 5 equals 10?

2

Now multiply both numerator and denominator by 2 to get our portion.

[tex]\frac{4*2}{5*2}[/tex]

[tex]\frac{8}{10}[/tex]

Now we have the same denominator, let's add our two fractions and see how much we have left.

8/10 + 1/10

9/10

We have 1/10 missing, therefore 1/10 is the answer.

I'll answer problem 9 to get you started

Answer: Choice (2) 3x-1 = 2x+3

===============================================

Explanation:

We will plug x = 7 into each equation or inequality given to us. Then we determine if we get a true statement or not.

----------------

Let's start with choice (1)

x + 3 > 6

7 + 3 > 6 .... x is replaced with 7

10 > 6

Since 10 is larger than 6, this makes the last inequality true. Therefore, the first inequality is true when x = 7. So we can rule out choice (1) since we are looking for a false statement.

----------------

Move onto choice (2)

3x-1 = 2x+3

3*7-1 = 2*7+3 ... replace every x with 7

21-1 = 14+3

20 = 17

This is false since we don't get the same number on each side. Therefore, choice (2) is the final answer.

----------------

Since we found the answer, we can stop here. But let's keep going to check the others.

choice (3)

2(x+1) = x+9

2*(7+1) = 7+9 ... plug in x = 7

2*(8) = 16

16 = 16

We get the same thing on both sides, so the equation is true. We can rule out choice (3).

-----------------

Now onto choice (4)

[tex]-2x + 10 \le 0\\\\-2*7 + 10 \le 0\\\\-14 + 10 \le 0\\\\-4 \le 0\\\\[/tex]

This is true since -4 is to the left of 0 on the number line, which makes -4 smaller than 0. We can rule out choice (4).
