What value of Y makes the equation true ?

Answers

Answer:

y = -5/2 or -2.5

Step-by-step explanation:

3y + 4 = -y - 6

add y to both sides

4y + 4 = -6

subtract 4 from both sides

4y + 4 - 4 = - 6 - 4

4y = -6 - 4

4y = -10

divide both sides by 4

4y/4 = -10/4

y = -10/4

y = -5/2 or -2.5

3. What is the value of x?
x = 41
x = 43
x = 47
x = 135

Answers

Answer:

x = 135

Step-by-step explanation:

The two angles form a straight line so their sum is 180

x+2 + 43 = 180

Combine like terms

x+45 =180

Subtract 45 from each side

x+45-45 =180-45

x = 135

The correct answer is 135

Find the area of a circle with a diameter of 56 millimeters. Round your answer to the nearest hundredth.

area: about ???
mm2

Answers

9514 1404 393

Answer:

2463.01 mm²

2461.76 mm² if you use 3.14 for π

Step-by-step explanation:

The formula for the area of a circle is ...

A = πr²

where r is the radius, half the diameter.

For a diameter of 56 mm, the radius is 28 mm. Using that in the formula gives an area of ...

A = π(28 mm)² = 784π mm²

For an appropriate value of π, the area is ...

784π mm² = 2463.00864... mm² ≈ 2463.01 mm²

For 3.14 as the value of π, the area is ...

784(3.14) mm² = 2461.76 mm²

_____

Comment on pi

Quite often these problems expect you to use 3.14 for pi. The required answer has 6 significant digits, so the use of a 3-digit value for pi is not appropriate. Rather, the value used should be 3.141493 or even more accurate.

On the first side it shows 5 ones. If you add 5 by 2 it’s 7. Then on the other side it shows 3 X’s. 3x2 is 6. Plus you add that 1 which makes it 7.

Hope this Helps :)

Each X has a value of 2. In the first section there is one X and 5 1s, this equals 7. In the second section 3 X and a single 1, if they equal 2 then its 3 • 2 = 6 + 1 making them both 7

Lucy wants to buy a basketball that costs $30. She lives in a state that has 10% sales tax. What is the final price she will pay for the basketball including tax?

Answers

Answer:

I think 33 dollars

Step-by-step explanation:

Cost of the ball= $30

Sales tax= 10 %

Amount to be paid as tax = 10/100 x 30 = $3

Final price = MP + Tax = 30 + 3 = $33

To solve anything for tax, you can do it in one step, or 2 steps. To solve it in one step, simply put the tax amount into a decimal, with a one in front. So for this question, you would put 1.10 and multiply by the amount. So 30x1.10=$33. Or you can just multiply 30 by a decimal with a 0. So 0.10x30=3. Then add the 3 to 30

Answers

Answer:

The solution is:

a. -18

b. -18

c. 24

d. 0

e. -4

4. 4

Step-by-step explanation:

Before we get into the solution, we remember the formula first, namely:

Addition

• (-) + (-) = (-)

• (+) + (+) = (+)

Subtraction

• (+) - (+) = can (-) and (+)

• (+) - (-) = (+)

Multiplication

• (-) x (-) = (+)

• (+) x (-) = (-)

Division

• (-) : (-) = (+)

• (+) : (-) = (-)

Solution:

a. 6(-3) = -18 ((+) × (-) = (-))

b. -6(3) = -18 ((-) × (+) = (-))

c. (-8)(-3) = 24 ((-) × (-) = (+))

d. -8(0) = 0 (whatever the number, if multiplied by 0 the result is still 0)

e. -20÷5 = -4 ((-) ÷ (+) = (-))

f. -36÷(-9) = 4 ((-) ÷ (-) = (+))

If you pay attention to the exercises above, you might see some things that will help you work through the essay or check your own essay:1) You should consider building your introduction with the context. Figure out a way to transition that context to your thesis statement (the main claim of your essay.) That main claim should be the last sentence in your introduction. So, if you go back and look at your introduction, you should A) have an interesting and informative title, B) provide enough information so that you audience understands the context and situation you are addressing and why you are addressing it, and C) a clear, specific statement of your thesis.2) The reasons you listed for believe your claim should be the basis for your body paragraphs. A) You will have to decide how many paragraphs you will need. It's possible you can do this as one reason per paragraph. But it is also possible it may take more than one paragraph for a single reason. B) Remember, a paragraph should only focus on one main topic. Make sure you have unity in each of these paragraphs. (This is an idea you should remember from reading from the Oxford chapters.) This need for unity will help you determine how many paragraphs you need. If you only need to develop one idea, you only need one paragraph. But if you need to develop multiple ideas, you will need multiple paragraphs. C) Remember, a paragraph should have adequate development. (This is an idea you should remember from reading from the Oxford chapters.) Development is a place that may help you determine the need for a paragraph too. If you find that you have to use more than three hundred words to develop an idea, you might need to divide that idea into to two smaller ideas. (It's usually a good idea to try to keep the majority of your paragraphs in the one-hundred and fifty to two-hundred word range.)3) The reasons you listed that counter your claim should also be a part of your essay body. Again, you will have to decide how many paragraphs are need. It's possible that one will do. You might, however, have to have several. Just make sure you counter claims that might be against your idea. (One way to think of them, is to turn your reasons into the opposite. If someone might reasonable say that, it could be a counter.4) Finally, you should use the paragraph you made describing what you proved in your essay as the basis for your conclusion.whoever can write me a good argumentive essay or a BS essay will get sent the money if you don't know what a BS essay is just do an argumentive one need it by 1pm 12/17 no later than 1:30if you are able to make the essay about lipgloss and lip scrubim also giving 15 points Replace underlined words with indirect objects (me, te, lui, nous, vous,leur) Remember that pronouns like me and te change tom' > and < t' in front of vowels. your 3 math answer scores are 75,98 and 91 what is your average score Which of these is NOT one of the commonly used words that begins an added-detail fragment?
