3x + 3 = -2x - 7 what is the value of x hurry!!

Answer:

7.5 hrs.

Step-by-step explanation:

First we need to find how much Magan earns per hour using the slope-intercept form: y = mx + b

Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

We will be using: (4, 70.80) and (9, 159.30) to find the slope of this table..

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{159.30-70.80}{9-4} \\\\m=\frac{88.50}{5} \\\\m=17.7[/tex]

y = mx + b

y = 17.7x + b

I will be using (4, 70.80) to find the value of b

(4, 70.80)

y = 17.7x + b

70.80 = 17.7(4) + b

70.80 = 70.80 + b

-70.80  -70.80

0 = b

y = 17.7x + b ==> y = 17.7x + 0 =  OR  y = 17.7x (since the value of b is 0)

The question wants us to find out how long it took Magan to make $132.75

y = 17.7x

132.75 = 17.7x

/17.7        /17.7

7.5 = x

This means that it took him 7.5 (seven and a half) hours to make $132.72

Answer:

Options 1 and 2 are proportional, the last one isn't.

Step-by-step explanation:

I found option 1 by dividing 8 / 1, then multiplying it by 2 to see if I get 16. I got 16 so it's proportional.

I found the 2nd option by dividing 9 / 4, and then multiplying it by 8 to see if I get 18. I got 18 so it's proportional.

I found option 3 by dividing 16 / 6, and then multiplying it by 4 to see if I get 10. I didn't 10, so it isn't proportional.

Answer:

1982 ÷ 18 = 109  

Step-by-step explanation:

The operator must be division. It must be in the fourth or fifth place, to make the numerator greater than the denominator.

In the fourth place,

1982 ÷ 18 = 109

Answer:

x=35

Step-by-step explanation:

The sum of the angles of the triangle is 180

x+10  + x  + 3x-5  = 180

Combine like terms

5x +5 = 180

Subtract 5 from each side

5x+5-5= 180-5

5x = 175

Divide each side by 5

5x/5 =175/5

x=35

Step-by-step explanation:

the mean is average

to find the mean add all number then divide by how many there are sooo

(4 + 7 + 13 + 3 + 9)/ 5

36/5

7.2

A data set's mean is the average of a data set. The mean of this data set is 7.2.

A data set's mean (average) is calculated by summing all of the numbers in the set and dividing by the number of values in the set.

The mean of this data set can be written as,

[tex]\rm Mean = \dfrac{4+7+13+3+9}{5} = 7.2[/tex]

Hence, the mean of this data set is 7.2.

===================================================

Explanation:

The given equation is in the form y = mx+b

m = -3/2 is the slope

b = 2 is the y intercept

The y intercept tells us where the graph crosses the vertical y axis. In this case, it's at 2 on the y axis. Think of the y axis as a number line that is simply vertical.

So we'll have (0,2) as one point on the line.

From this point, move down 3 units and to the right 2 units to arrive at (2,-1) as our next point. We only need two points to graph a straight line. You can repeat the process "down 3, over to the right 2" to generate as many points as you want.

The "down 3, over to the right 2" is from the slope -3/2

slope = rise/run = -3/2

rise = -3 means we move down 3

run = 2 means we move to the right 2

---------------------

Another approach is to plug in numbers for x to get corresponding values for y.

If we pick on x = 0, then,

y = (-3/2)*x + 2

y = (-3/2)*0 + 2

y = -1.5*0 + 2

y = 0 + 2

y = 2

So this shows (0,2) is one point on the line.

If we plug in x = 2, then,

y = (-3/2)*x + 2

y = (-3/2)*2 + 2

y = -1.5*2 + 2

y = -3+2

y = -1

Meaning (2,-1) is another point on the line.

Knowing the difference between the gain and the loss is essential to determine if a result is positive or negative, especially in commercial or economic operations.

Thus, the existence of a greater amount of negative elements than positive ones will imply a loss, with which it will not be recommended to carry out the activity given the high risk of loss.

In this way, a previous study of the conditions and probabilities of the operation can prevent losses and favor positive results.

Step-by-step explanation:

Answer:

Plastic, the wonder material that we use for everything and which pollutes our environment, is perhaps the most harmful of trash dumped by mariners and sea-goers in sea because it does not readily break down in nature. In-fact, the plastic that goes over the side today may still be around in hundreds of years to foul up the fishing gear, boat propellers, and beaches of future generations.

Careless disposal of plastic can have dire consequences. A plastic bag looks like a tasty jellyfish to an indiscriminate feeder like the sea turtle, but plastic is indigestible. It can choke, block the intestines of, or cause infection in those animals that consume it.

A plastic bag can also clog an outboard engine’s cooling system. Lost or discarded monofilament fishing line can foul propellers, destroying oil seals and lower units of engines, or it can become an entangling web for fish, seabirds, and marine mammals.

According to the Centre for Marine Conservation, over 25,000 pieces of fishing line were collected from U.S. beaches during the 1996 annual beach clean-up and at least 40% of all animal entanglements reported during the clean-ups involved fishing line.

Every day, more and more plastic is accumulating in our oceans. Recreational boaters are not the only group that improperly disposes off plastic refuse at sea. Plastics also enter the marine environment from sewage outfalls, merchant shipping, commercial fishing operations, and beachgoers.

Answer: 35!

Step-by-step explanation

The length is 7 and the width is 10 so length x width = area which is 7x10=70. The area of the small rectangle is 5x7 which is 35. So altogether 70+35=105. and you would have to subtract it because you only want to know the length of the frame. So 70-35=35!

==================================================

Explanation:

Let's find the distance between the two given values

Let a = -2.8 and b = -7.2

Subtract a and b, then apply absolute value to ensure the result isn't negative.

|a-b| = |-2.8-(-7.2)|

|a-b| = |-2.8+7.2|

|a-b| = |4.4|

|a-b| = 4.4

The distance from -2.8 to -7.2 is 4.4 units.

To go from -2.8 to -7.2, we moved 4.4 units to the left.

Let's go back to -2.8 and now move 4.4 units to the right.

So we add 4.4 onto -2.8 getting

-2.8+4.4 = 1.6

The diagram is shown below.

On a number line, the number 1.6 is the same distance from −2.8 as −7.2 the answer is 1.6.

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

It is given that two numbers on a number line that is:

-2.8 and -7.2

To find the other number that is the same distance from −2.8 as −7.2:

Mathematically, we can write a number expression:

= -2.8 -(-7.2)

= -2.8 + 7.2

= 4.4

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division.

Accordingly, -7.2 is 4.4 units distant from -2.8.

= -2.8 +4.4

= 1.6

Thus, on a number line, the number 1.6 is the same distance from −2.8 as −7.2 the answer is 1.6.
