Answer:

x=25

Step-by-step explanation:

To figure out this equation, you need to remove 5 (which is a multiply as its multiplying by x) from the first side by dividing (divide as you do the opposite operation, divide is the opposite of multiply) it by the other.

x= 125 divided by 5

x=125/5

x=25

It's very easy, just try raising 5 to different powers until you get 125.
5^1 = 5
5^2 = 5*5 = 25
5^3 = 25*5 = 125
Ah, x is 3!

Can someone also explain how to get the answer thank u

Answer:

$m = -\frac{194}{3}$

Step-by-step explanation:

I'm assuming you are trying to find m. In order to do so, you need to get m on one side.

Before doing that let's multiple -2 and -3m by $\frac{4}{3}$

$256=-\frac{8}{3} - 4m$

add $-\frac{8}{3}$ to both sides

$258\frac{2}{3}=-4m$

I would get rid of the fraction so I'd multiply both sides by $\frac{3}{1}$

$\frac{776}{3}*3 = 4m*3$

$776=-12m$

divide both sides by -12m

$m = -\frac{776}{12}$

which can be simplified to

$m = -\frac{194}{3}$

ALL UNLESS THAT $\frac{4}{3}$ IS A POWER

A service station checks Mr. Smith's radiator and finds it contains only 40% antifreeze. If the radiator holds 20 quarts and is

storchak [24]

Answer:

8 quarts

Step-by-step explanation:

Step One: Figure out how much 40% is by making an equation:

Since we are looking for a percentage, we use cross multiplication to find X.

$\frac{x}{20} = \frac{40}{100}$

Step Two: multiply 20 by 40 to start cross multiplying:

20 times 40 is 800, so replace the 40 by 800 in the equation.

$\frac{x}{20} = \frac{800}{100}$

Step Three: divide 800 by 100, and we will have X:

800/100=8

X=8 aka 8 quarts

I hope this helps!

pls give thx and brainliest :D

It would be the second distribution in the fist picture, and the first distribution in the second picture

Step-by-step explanation:

The median is the middle number of a set of numbers, for example, the median in 3, 5, 9, 10, 11, 15, 20 would be 10, since it is the middle number. For the two distributions, that is the best measure of center

Lorico [155]

The median is a better representative of the central value of a data set when
the data set is highly skewed.

Note that
The median and average value only coincide when the distribution is perfectly normal.
Many outliers will also skew the distribution, and the median becomes a better representative.
