Remember that all triangles add up to 180. The triangle has congruent markings, therefore our equation will look like this:

11x-65+11x-65+29=180
Combine like terms.
22x-101=180
Add 101 to both sides.
22x = 281
Divide both sides by 22.
x = 12.77

Pocahontas wants to buy a tennis racket that is 70% off. The original price is $156.33. What is amount of discount (nearest penny)?
What is the sale price (nearest penny) please show your work

Answers

1. You could plug this into the calculator as either 70% of 156.33 or 0.7 × 156.33, but either way you know the discount is going to be $109.43

2. We got the discount, so all you have to do is subtract it from the original. 156.33 - 109.43 = $46.90 which is the sale price! I hope this helps

A line with a slope of -4 passes through the point (0, 0). What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer: y = -4x

Step-by-step explanation: You would use the formula y = mx + b to solve your problem. When you plug the numbers in, you get y = -4x. There would be no "+ b" because in this case, the y-intercept (b) is equal to zero. Therefore, you would not need to write "y = -4x + 0" because that would not be the equation in its simplest form.

Simplify each expression by using the distributive property and combining like terms.
3 ● (2x - 4) - 4x

Answers

Answer:

2x - 12

Step-by-step explanation:

Hello!

So, let's simplify using the distributive property.

Let's look at 3(2x - 4). You want to multiply 3 by every term inside the parentheses.

3*2x = 6x

3*-4= - 12

So now our expression looks like this:

(6x - 12) - 4x

Now we combine like terms. Our only like terms are 6x and -4x.

6x - 4x = 2x. So, our simplified expression is:

2x - 12.
