Describe The Angle Relationship And Solve For The X.

Answers

Answer 1

Answer:

x = 25

Step-by-step explanation:

The shown angles appear to be on a straight line

Angles on a straight line have a sum of 180°

That being said we can create an equation using this relationship

180 = x + 2 + 153

now we solve for x using basic algebra

step 1 combine like terms

153 + 2 = 155

now we have 180 = x + 155

step 2 subtract 155 from each side

180 - 155 = 25

155 - 155 cancels out

we're left with x = 25

A sign says that the price on all music equipment is 30% off the original price. you buy an electric guitar for the sale price of $315.
A-what is the original price?
B-How much money did you save off of the original price?
C-What percent of the original price is the sale price?

Answers

Answer:

a. So the electric guitar is sold for a sale price of $315 after the discount. The discount was 30%. Even though we get that amount off, we still pay 70% of the original price, because 100% (original price) - 30% is 70%.

b. An equation that can help us find the regular price of the item is through writing and solving a proportion. Set it up like this:

315/x = 70/100

This is because 315 is part of the whole and is 70% of the value of x.

Step-by-step explanation:

Okay. Let's solve this by cross multiplying the values. 315 * 100 is 31,500. 70 * x is 70x. That simplifies to 31,500 = 70x. Didivde each side by 70 to isolate the x. 70x/70 cancels out. 31,500/70 is 450. Let's check this by multiply the number by 70% and see what happens. 450 * 70% (0.7) is 315. There. x = 450. The regular price was $450.

Answer:

a. $450

b. $135

c. 70%

Step-by-step:

[tex]\frac{70}{100} = \frac{315}{450}[/tex]  since these two fractions are equal to each other that means the orginal price is $450.

(sale price/original price)x100= % of original price

(315/450)x100=0.7=70%

Im pretty sure it’s B because it tells your the area which is 40 and the length which is 4. I don’t know how to explain it but hopefully it kinda of helped and it’s right.
It’s D.

Explanation: Since the area formula is A = bh/2, you would replace the variables with what you know. Since we know that the base is 4 and the area is 40, your equation would be 40 = (4)(h)/2. To solve, you would simplify the (4)(h)/2 to 2h because 4 divided by 2 is 2. You’re left with 40 = 2h and then you divide by 2 to get h by itself, 40 divided by 2 is 20, therefore the height is 20 inches.

Rachel found that the time it takes for her to make her favorite desert decreases the more times she makes its. The time is takes in minutes(M) can be modeled by: M=72-0.75n, where n is the number of times that rachel has made the desert.
A. how long will it take rachel to make her desert the fifth time?

B. after how many times will rachel be able to make her desert in 63 minutes?

C. How long will it take rachel to make her desert the 40th time? Do you think this is reasonable?

Answers

Answer:

A: 68.25 minutes

B: 12 times

C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.

Step-by-step explanation:

a: 72 -0.75*5 = 68.25

b: M=63=72-0.75n

subtract 72 from each side: -9 = -0.75n

divide each side by -0.75: n = 12

so 12 times

c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.

Pheobe had 6 keys. She paid with a $10.00 bill and received $3.28 change. How much did it cost to have EACH key made

Answers

Answer:

$1.12

Step-by-step explanation:

One way to solve this problem is through an algebraic equation. Set up the equation like this, [tex]10-3.28=6x[/tex]. This equation works because 3.28 is subtracted from 10, which represents how much was spent in total. Then, this is equal to 6x, which represents the total cost of six keys.

So, to solve first subtract 3.28 from 10, this gives you 6.72. Then, divide both sides by 6. This equals 1.12, which is the cost of each key.
