Answer:

$F=\frac{9C+160}{5}$

Step-by-step explanation:

$C=\frac{5(F-32)}{9}$

Multiply both sides with 9.

$9C=5(F-32)$

Use distributive property.

$9C=5F-160$

Add 160 to both sides.

$9C+160=5F$

Divide 5 to both sides.

$\frac{9C+160}{5}=F$

Answer:

$\frac{9c + 160}{5}$

Step-by-step explanation:

C = 5(F - 32)/9

so we do a little algebra here

9C = 5F - 160

we move both side

5F - 160 = 9C

5F = 9C + 160

so in the end

F =

$\frac{9c + 160}{5}$

a = 9

b = 160

c = 5

Which expression is equivalent to \frac{10q^5w^7}{2w^3}.\ \frac{4\left(q6\right)^2}{w^{-5}} for all values of q and w where the

mestny [16]

Answer:

$\frac{10q^5w^7}{2w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}} =20q^{17}w^9$

Step-by-step explanation:

Given

$\frac{10q^5w^7}{2w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

Required

Determine the equivalent expression

$\frac{10q^5w^7}{2w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

Simplify the first fraction

$\frac{5q^5w^7}{w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

Apply law of indices on the first fraction;

$5q^5w^{7-3}.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

$5q^5w^4.\ \frac{4\left(q^6\right)^2}{w^{-5}}$

$\ \frac{5q^5w^4*4\left(q^6\right)^2}{w^{-5}}$

Apply law of indices:

$5q^5w^4*4\left(q^6\right)^2 * w^{5}$

Evaluate the bracket

$5q^5w^4*4 * q^{12} * w^{5}$

Collect Like Terms

$5*4q^5* q^{12}*w^4 * w^{5}$

$20q^5* q^{12}*w^4 * w^{5}$

$20q^{5+12}*w^{4+5}$

$20q^{17}w^9$

Hence:

$\frac{10q^5w^7}{2w^3}.\ \frac{4\left(q^6\right)^2}{w^{-5}} =20q^{17}w^9$

Jen has 3 bags of pears. If Jen gives the same number of pears to 4 friends. How many pears will each friend get

NISA [10]

Answer:

Each friend will get<u> 3 </u>pears.

Step-by-step explanation:

The question is incomplete and the complete question is:

Jen has 3 bags of pears. Each bag has 5 pears. If Jen gives the same number of pears to 4 friends, how many pears will each friend get?

Now, to find the number of pears each of the 4 friends get:

So, as given:

Number of bags of pears = 3.

Number of pears each bag has = 5.

Thus:

Total number of pears = $3\times 5=15.$

Total number of friends = 4.

So, to get the number of pears each get we divide total number of pears by total number of friends:

$15\div 4$

$=3.75.$

<u><em>Thus, if Jen gives same number pears to 4 friends 3 pears each will get.</em></u>

Therefore, each friend will get 3 pears.

The ratio of blue marbles to red marbles in a box is 3 to 2. if there are 12 blue marbles in a box then how many red marbles are

valkas [14]

The answer is: 8 red marbles!

This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x

We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8

If this helped, give me brainliest :)
