-5x - 3 < 2x – 18 hey ​

Answers

Answer:

x > 5

Step-by-step explanation:

2x - 5x < 3 - 18

-3x < -15

Divide everything by ÷ 3 and flip inequality because it's negative.

x > 5

Answer:

15/7 < x

Step-by-step explanation:

Simplify using PEMDAS, and remember that multiplying/dividing a negative flips the sign of the inequality.

-5x - 3 < 2x - 18  (Add 18 to both sides)

-5x + 15 < 2x (Add 5x to both sides)

15 < 7x (Divide both sides by 7)

15/7 < x

Заx + b = c
solve for x

Answers

X= c/3a - b/3a. Isolate the variable by dividing each side factor that doesn’t contain the variable.

Use Cavalieri’s Principle to calculate the exact volume of an oblique cylinder with a radius of 15 meters and a height of 12 meters.​

Answers

Answer:

2700pi [tex]m^{3}[/tex]

Step-by-step explanation:

The radius of cylinder is 15 meters and the height is 12 meters.

The volume of cylinder is

V = [tex]\pi r^{2} h[/tex]

Where, r is radius and h is height.

Substitute r = 15 and h = 12 in the volume formula.

V = [tex]\pi (15)^{2} (12)[/tex]

V = 2700[tex]\pi[/tex]

The volume of the cylinder is 2700[tex]\pi[/tex] m³.

Answer:

the answer should be 2700pi

What is the value of x?

Answers

Answer:

x = 20°

Step-by-step explanation:

Step 1:

x + 40° = 3x          Vertical Angles

Step 2:

40° = 2x       Subtract x on both sides

Step 3:

x = 40° ÷ 2       Divide

Answer:

x = 20°

Hope This Helps :)

These angles are opposite from each other, meaning they are the same.

Note: I'm pretty sure they are called opposite angles, but it's been a long time.

If they are the same, you would need to use an equal sign.

So the equation is x+40 = 3x

Now solve the equation. To remove the x from the left side, you subtract x.

(x+40)-x = (3x)-x

Note: Ignore the parentheses, they are used so you can clearly see the problem more (That doesn't make sense LOL).

Now we have 40 = 2x

Now we have to isolate the x, by removing the 2. Since 2 is multiplied to x, we have to divide it from both sides.

40÷2 = 2x÷2

You get 20 = x

Therefore, the value of x equals 20°

Solve the equation. Start Fraction y minus 5 over 3 End Fraction= 1 A. –2 B. 8 C. 18 D. 6

Answers

Answer:

B. 8

Step-by-step explanation:

Start Fraction y minus 5 over 3 End Fraction= 1

This statement above is written Mathematically as:

y - 5/3 = 1

We solve the Equation below

Step 1

y - 5/3 = 1

We cross Multiply

y - 5 = 3 × 1

y - 5 = 3

Step 2

Add 5 to both sides

y - 5 = 3

y - 5 + 5 = 3 + 5

y = 8

Medicare would like to test if the average monthly rate for one-bedroom assisted-living facility is different from $3,300. Suppose that you collect sample information and, based on the hypothesis test, determine that the z test statistic is equal to 1.98 while the critical value of z is 2.05. How would you state the conclusion?

Answers

Answer:

We fail to reject our null hypothesis and conclude that there is not sufficient evidence to conclude that the average monthly rate for one-bedroom assisted-living facility is different from $3,300.

Step-by-step explanation:

We are given that critical value of z=2.05

z test statistic=1.98

As we are testing that whether the the average monthly rate for one-bedroom assisted-living facility is different from $3,300, so this leads to two tailed hypothesis test as hypothesis are

Null hypothesis:μ=3300

Alternative hypothesis:μ≠3300.

The critical region in case of two tailed hypothesis test is

[tex]|z|>z_{\frac{\alpha }{2} }[/tex]

1.98>2.05 (which is not true)

So, the test statistic don't lie in rejection region, thus we don't reject our null hypothesis and conclude that there is insufficient evidence to conclude that the average monthly rate for one-bedroom assisted-living facility is different from $3,300.

Mark bought a computer and it depreciated over 5 years, using the straight line method. The computer was worth $2,350 in 2005 and in 2010 it was worthless. How much was it worth in 2008?

Answers

Answer:

The computer was worth $970 in 2008

Step-by-step explanation:

The reason for this is that when you are trying to solve these types of problems use below:

2350/5 = 470

starting price / years = per year loss

2350 - 470 = ? three times for three years till 2008

The answer then is $940 in 2008.
