Answer:

Where is the question???

Step-by-step explanation:

Answer:

0.04 h

Step-by-step explanation:

The given equation is :

8h=200

It is used to find hours h a person needs to work to earn $200 at $8 per hour.

We need to find no of hours does a person need to work to earn $200. It can be calculated as follows :

[tex]\dfrac{8h}{200}=\dfrac{200}{200}\\\\h = 0.04\ h[/tex]

So, for $200, the person will need 0.04 h.

if there no other info given to you then I guess the answer would be x = 2 since (a) would equal 6?

Answer:

  x = 12/a

Step-by-step explanation:

To find the value of x, divide both sides of the equation by its coefficient.

  ax = 12

  (ax)/a = 12/a

  x = 12/a

Step-by-step explanation:

x+y=180

x=180-y------(i)

x-y=70------(ii)

Now,

Putting the value of x in equation (ii)

x-y=70

(180-y)-y=70

180+2y=70

2y=70-180

2y= - 110

y= - 110/2

y= - 55

Again,

x=180-(-55)

x=235

x-y=70

x-(-55)=70

x+55=70

x=70-55

x=15

Answer:

Meanings of the numbers:

Most numbers represent an amount. Positive numbers represent above zero. Zero is the only number that does not represent an amount. It means nothing. When you go lower than nothing, you are in the negative numbers. Negative numbers represent absent values pretty much.

How I would use them in every day life:

I would use positive numbers to represent... maybe something I'm trying to get at a store. Ex: 4 bananas

I would use negative numbers to... maybe look at the temperature. Ex: -16 degrees Fahrenheit. Negative numbers are in temperature all the time.

Hope this helps! (^-^)

Answer:

4 packages

Step-by-step explanation:

We have to do 980/250.

So after you get that, you would get 3.92. It would not make sense to get 3.92 packages since that isn't possible on Amazon using common sense. Therefore we must round 3.92 to 4 packages.

Answer: ∠ECB = 60°

Step-by-step explanation:

First, find the value of x by adding them up.

x + 3x + 2x = 6x

Since we know that all of the angles create a 180° angle, we can set up a proportion.

6x = 180°

To find the value of x, divide both sides by 6.

6x ÷ 6 = x

180 ÷ 6 = 30

So now the proportion is x = 30.

Now that we now x = 30, we can plug in 30 to the angle measures.

∠DCA = 30°

∠DCE = 90°

∠ECB = 60°

So angle ECB is 60°.

Answer:

B.) -1

Step-by-step explanation:

Here, 3x + 2(x - 9) = 8x + x - 14 is given

Now, we will solve and we get,

3x + 2(x - 9) = 8x + x - 14

3x + 2x - 18 = 9x - 14

5x - 9x = 18 - 14

-4x = 4

4x = -4

x = -4÷4

x = -1

Thus, The value of x is -1

Hence, Option B is correct

Answer:

32

Step-by-step explanation:

f(x) = 7, so:

5 · 7 - 3= 35 - 3 = 32

Answer:

x = 2

Step-by-step explanation:

f(x) = 5x - 3    

7 = 5x - 3

10 = 5x

2 = x

So, x = 2

Answer:$71.50

Step-by-step explanation:

Hello!

So first you want to find out how many bottles of soap you can make

To do that you want to divide how many ounces you have by how many ounces it takes to make 1 bottle

97.5 / 7.5 = 13

So you know you can make 13 bottles of soap

So now you want to multiply the number of bottles of soap that can be made by the amount of money you can make per bottle

13 * 5.50 = 71.50

So you know that the students can make $71.50

Answer:

B

Step-by-step explanation:

m = 3/4

x1 = 2

y1 = 1

Using the formula,

y - y1 = m(x - x1)

y - 1 = 3/4(x - 2)

y - 1 = 3x/4 - 3/2

y = 3x/4 -3/2 + 1

y = 3x/4 - 1/2 (×4)

4y = 3x - 2

Therefore, the answer is B

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The equation of the line that passes through (2, 1) and 3/4 as its slope.

4y = 3x - 2

Option B is the correct answer.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Slope = 3/4

m = 3/4

The point that passes through = (2, 1)

Now,

The equation of the line is y = mx + c.

y = (3/4)x + c

We will take (2, 1) = (x, y) since it passes through the line.

1 = (3/4)2 + c

1 = 3/2 + c

c = 1 - 3/2

c = -1/2

Now,

The equation of the line that passes through (2, 1) and 3/4 as its slope.

y = (3/4)x -1/2

y = (3x - 2)/4

4y = 3x - 2

Thus,

The equation of the line that passes through (2, 1) and 3/4 as its slope.

4y = 3x - 2

Option B is the correct answer.

Answer:

y = 17.5

Step-by-step explanation:

Given that y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition y = 35 when x = 140, then

35 = 140k ( divide both sides by 140 )

0.25 = k

y = 0.25x ← equation of proportion

When x = 70, then

y = 0.25 × 70 = 17.5
