Susan can run 3.5 miles in 40 minutes. About how many whole minutes would it take her to run 8 miles at this same rate? Set up and solve a
proportion. Show all work and answer the situation.

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]

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:

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:

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: 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.

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:

you just divide

Step-by-step explanation:

Just divide the top of the fraction by the bottom, and read off the answer!

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:

[tex]MP= (-6,3)[/tex]

Step-by-step explanation:

[tex]MP= (\frac{x_1+x_2}{2} )(\frac{y_1+y_2}{2} )\\MP= (\frac{6+-6}{2} )(\frac{12+-6}{2} )\\MP= (\frac{-12}{2} )(\frac{6}{2} )\\MP= (-6,3)[/tex]

Yes

Step-by-step explanation:

The constant is $1.75 each

Answer: 2c + 6x - 28

Step-by-step explanation:

6x -18 + 2c - 10

add like terms

2c + 6x - 28

Answer:

9 feet

Step-by-step explanation:

2 1/4 can be written as an improper fraction 9/4

we are given:

1 inch ----> corresponds to 4 feet

hence,

2 1/4 inch ---> corresponds to 4 feet x 2 1/4 = 4 x (9/4) = 9 feet

Answer:

Step-by-step explanation: the triangle is negative 6, plus 18 half in the middle.

Answer:

9.6cm

Step-by-step explanation:

Since the radius is half of the diameter, to find the diameter, simply multiply the radius by 2.

4.8*2=9.6

Diameter=9.6cm

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!

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.
