What is the solution to -3m = -15

Answers

Answer:

[tex]m=5[/tex]

Step-by-step explanation:

[tex]-3m=-15[/tex]

Divide both sides by -3:

[tex]\frac{-3m}{-3}=\frac{-15}{-3}[/tex]

[tex]m=5[/tex]

Answer:

[tex]m = 5[/tex]

Step-by-step explanation:

Solve for [tex]m[/tex] :

[tex]-3m = -15[/tex]

-Take [tex]-3m[/tex] and divide it on both sides of the equation:

[tex]\frac{-3m}{-3} = \frac{-15}{-3}[/tex]

[tex]m = 5[/tex]

Therefore, the value of [tex]m[/tex] is [tex]5[/tex].

Solve this equation.

Answers

Answer:

5(x+8)-1=20+2(x+8)

or, 5x + 40 -1 = 20 + 2x + 16

or, 5x-2x = 20+ 16 -39

3x = -3

x = -1

Step-by-step explanation:

Rewrite (x – 3) (x + 5) + (x – 3) (2x – 1) as the product of two binomials.​

Answers

(x - 3)(x + 5) + (x - 3)(2x - 1)

We can factor out (x - 3) since both terms have that in common. Then we simply add together x + 5 and 2x - 1

(x - 3)(3x + 4) is the final answer.

Which two numbers of the given data set have the same absolute value? Explain your answer in full sentences.

-5, 5, -3, 8
pls help. ;)

Answers

Answer:

The answer is -5 and 5 because when you do absolute value if there is a negative number then it turns into a positive number. Negatives will always turn out as positives when doing absolute value. :)

Step-by-step explanation:

Answer: the two numbers that have the same absolute value is -5, and 5.

Step-by-step explanation:

Absolute will just make any negatives to positive.

So, the absolute value of -5 is 5,  or the absolute value of -3, is 3.

If it's already positive, then nothing happens; it stays the same

So, the absolute value of 8 is 8, nothing is changed.

the price of gravel is $24 for every 3/8 ton. kate wants to know the price of 2 tons of gravel

Answers

Answer:

$128

Step-by-step explanation:

your looking for 16/8, divide 16 by 3, leaving you with 5.333...

now times that by $24, and you have your answer hope this helps

The price of 2 tons of gravel is $128.

Given:

The price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.  

To find:

The price of 2 tons of gravel.

Explanation:

Let [tex]x[/tex] be the price of 1 ton of gravel.

Then the price of [tex]\dfrac{3}{8}[/tex] ton is [tex]\dfrac{3}{8}x[/tex] and the price of 2 tons of gravel is [tex]2x[/tex].

It is given that the price of gravel is $24 for every [tex]\dfrac{3}{8}[/tex] ton.  

[tex]\dfrac{3}{8}x=24[/tex]

[tex]x=\dfrac{8}{3}\times 24[/tex]

[tex]x=8\times 8[/tex]

[tex]x=64[/tex]

Now, the price of 2 tons of gravel is:

[tex]2x=2(64)[/tex]

[tex]2x=128[/tex]

Therefore, the price of 2 tons of gravel is $128.

Leslie ran a total of 8 miles over the course of 4 track practices. How many miles would Leslie have ran after 5 track practices? Solve using unit rate.

Answers

Answer:

10 miles

Step-by-step explanation:

Find how much she runs during one track practice by dividing 8 by 4. This gives you the equation 2x, with x being the number of track practices.

Answer: 10 miles after 5 track practices.

Step-by-step explanation: Lets find the unit rate of this problem. Remember that unit rate means the denominator will always have a 1.

8/4 converted to a unit rate is 2/1

The unit rate is 2 miles per every 1 track practice.

We can use the unit rate to solve how many miles Leslie would have ran after 5 track practices.

2/1 x 5 = 10/5

So, Leslie would have ran 10 miles after 5 track practices.

Mia has applied to be a lifeguard for the summer. The lifeguard job is three days a week with hours and
the table below.
Hours worked
Amount paid
Tuesday
6
$52.50
Thursday
8
$70,00
Saturday
5
$43.75
Which statement best describes the hourly rates?
O The two jobs pay the same hourly rate.
The comparison cannot be made with the information given.
O Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.
Jason's camp counselor job pays a lower hourly rate than Mia's lifeguard job.

Answers

Answer:

The correct statement is (3).

Step-by-step explanation:

Jason's hourly pay rate as a camp counselor for the summer is:

J = $9 / hour.

The table representing Mia's pay as a lifeguard for the summer is as follows:

 Days             Hours worked             Amount paid

Tuesday                    6                            $52.50

Thursday                   8                            $70,00

Saturday                    5                            $43.75

Compute Mia's hourly rate for Tuesday: [tex]\frac{\$52.50}{6}=\$8.75[/tex]

Compute Mia's hourly rate for Thursday : [tex]\frac{\$70.00}{8}=\$8.75[/tex]

Compute Mia's hourly rate for Saturday: [tex]\frac{\$43.75}{5}=\$8.75[/tex]

Thus, Mia's hourly rate  as a lifeguard for the summer is,

M = $8.75 / hour

This implies that Jason's camp counselor job pays a higher hourly rate than Mia's lifeguard job.

Thus, the correct statement is (3).

Answer:

what coordinate expression represents the coordinates of any point after dilation by any scale factor, a?

Answers

Answer:

(x,y) → (ax,ay) .

Step-by-step explanation:

A dilation is a transformation that changes the size of the image. It either shrink or enlarge a shape by using a scale factor about a center of dilation.

If we transform point (x,y) by using dilation with scale factor k (assume center of dilation at (0,0) then the coordinate of the image will be (kx,ky).

So, the coordinate expression represents the coordinates of any point after dilation by a scale factor of a:

(x,y) → (ax,ay) .

Answer:

[tex]\huge\boxed{(ax, ay)}[/tex]

Step-by-step explanation:

In order to dilate the coordinates of a point, we want to make it [tex]a[/tex] times bigger. In order to do this, we can multiply the x and y values by our scale factor, a. This is called mapping. What it does is it basically multiplied our points by a specific number so that we end up with a figure that is [tex]a[/tex] (the scale factor) times bigger than the original.

So in order to make an expression for this, we multiply the x and y coordinates by a. So we have ax and ay.

An astronaut is returning to earth in a spacecraft. If the spacecraft is descending at a rate of 13.81 kilometres per minute,what will be its change in height after 5 and 1/2 minutes.Round your answer to the nearest kilometer.

Answers

Answer:

-76

Step-by-step explanation:

I give credit to the other people that said it, I am not the smart one her lol

The change in height after 5 and 1/2 minutes to the nearest kilometer will be 75.955

What is the fundamental principle of multiplication?

If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

we have been given that the spacecraft is descending at a rate of 13.81 kilometres per minute, then  change in height after 5 and 1/2 minutes will be;

WE can see that the astronaut is descending 13.81 km each minute, so multiply that by 5 and a half minutes .

Then multiply 5 and 1/2 minutes by 13.81,

Speed = distance / times

Rate = 11/2 x 13.81

Rate = 75.955

Therefore, The change in height after 5 and 1/2 minutes to the nearest kilometer will be 75.955
