solving multistep linear equations and inequalities
help me please​

Answer:

I hope it helped you and you understood it.

Answer:

we know that,

Force is directly proportional to rate of change of momentum.

→ F [tex]\propto[/tex] (Pv - pu)/t

→ F = k p (v - u)/t

→ F = k p a

Here, body must have some mass.

→ F = ma

Derived.

Answer:

1/40

Step-by-step explanation:

You put 4/1 to put it into a fraction and then flip the fraction to times 1/10 (1/4)

to get the answer of 1/40

Answer:

A rectangle can be reflected across an axis of symmetry so that it carries onto itself twice. Rectangles are geometric shapes with two lines of symmetry. One line of symmetry divides a rectangle in half horizontally, and the other line divides the shape in half vertically.

Step-by-step explanation:

Two times.

Or four times if the rectangle happens to be a square.

Answer:

(4,3)

Step-by-step explanation:

This doesn't even take any math really, just deductive reasoning :)

We know the line segment stretches from one to 15, meaning there are 14 points on the line as there is (1,2,3, etc.)

14/2 obviously equals 7, so just plug it in from there.

12 is too far up on the line to be less than half, so (12, 3) is wrong

^ this goes for (9, 3) as well

7 is literally the halfway marker, so there is no way it could be (7, 3)

Making the answer (4, 3) because not only is it the last one remaining but it makes the most sense, being less than one half of the segment

2c + 6x - 28

Answer:

#6 is 17 days

Step-by-step explanation:

This is how I answered it

1) 2750 = 550 + 125x

2) subtract 550 from each side

2750-550=2200

so the left over equation is:

2200 = 125x

3) divide each side by 125 to get x by itself

2200÷125= 17.6

4) you are left with: x = 17 days

Answer:

1. X=13

2. X=2

3. X=12

4. X=5

5. X=1

6. X=33

7. X= - 2

8.X= - 6

9.X=3

10.X=1

Answer:

14!

Step-by-step explanation:

Subtract 5 from 19 and get 14!

The simplified form of the given expression is 75.

The given expression is 675 ÷ (6 + 9 ÷ 3).

We need to simplify the given expression.

PEMDAS is an acronym used to mention the order of operations to be followed while solving expressions having multiple operations. PEMDAS stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction

Now, in the given expression simplify the bracket.

That is, (6 + 9 ÷ 3)=(6+3)

=9

Now, 675 ÷ 9=75

Therefore, the simplified form of the given expression is 75.

Answer: Arithmetic sequences follow terms by adding, while geometric sequences follow terms by multiplying.

Step-by-step explanation: Please mark Brainliest!

Answer: There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.

(FULL CREDIT TO maksimylian, I DID NOT WRITE THIS ANSWER)

Answer:

Randomly surveying 50 girls would most likely bring non-seventh-graders into the sample.

The sample also does not take any boys into account, and they most likely make up about half of the seventh-grade population.

The results would not be a representative sample of the population.

Step-by-step explanation:

From edge

We know that 6x(-7) is -42 and we also know that 6+(-7) is -1.

So we can write

[tex]x^2+6x-7x-42[/tex]

[tex]x(x+6)-7(x+6)[/tex]

[tex](x-7)(x+6)[/tex]

So our solutions are [tex]x=7,-6[/tex]

Answer: So what my teacher always told me to do was act like a fraction was a tree. The tree always falls to the left which then outs the fraction as a division problem. You solve the division problem

Step-by-step explanation:

Ok so for example, lets use [tex]\frac{1}{2}[/tex]. Drawing it as a tree it then falls to the left. Therefore it becomes 1 ÷ 2. So 2 can not go into one therefore you need to put a decimal point at the top and add a zero behind the 1 under the bar. The 1 then becomes a 10, therefore 2 can go into 10 5 times. However the answer is not 5. You have to remember to bring the decimal point that you placed before the 5. In conclusion hte answer is .5 . This may be confusing because I am not able to include any photos but hopefully you'll get the point.

Answer:

-1/8

Step-by-step explanation:

1) -12 - 8 = -20

2) -20 = 5/2x

3) (-20)(2x) = 5

4) -40x = 5

5) x = -5/40 = -1/8

Hope this helps!

Hey there! I'm happy to help!

Let's see what makes 12x^5.

3·2·2·x·x·x·x·x

And for 8x^3...

2·2·2·x·x·x

We see that both of these have two 2s and 3 xs, so our GCF is 2·2·x·x·x which is 4x^3.

Have a wonderful day! :D

Answer:

-p^2-6r^2-2r-8

Step-by-step explanation:

When you simplify it you get that. Hope this helped :)

The solution to the given expression is -8 - 2r - p² - 6r² which is determined by performing the arithmetic operation.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The given expression is given in the question

(10 – 7r - p²) + (-6r² - 18 +5r)

Open the parentheses and rearrange the terms,

10 - 18 - 7r + 5r - p² - 6r²

Apply the arithmetic operation in the likewise terms,

-8 - 2r - p² - 6r²

Therefore, the solution to the given expression is -8 - 2r - p² - 6r²

Edgenuity’s sample response for this question:

Sublimation occurs because the atoms in a solid must gain enough energy to form a gass without passing through the liquid state. Low air pressure and large amounts of energy, often in the form of heat, allow the atoms to move fast enough to overcome the attractive forces between them.

If you need an original response here’s my take!!:

Sublimation happens when a solid turns directly into a gas. For this to happen, there must be low air pressure and immense heat energy. This allows atoms to quickly move and perform sublimation.
