Sum = (-3) + (-6) = -9

Yards gained are positive, and yards lost are negative.

If you lose 3 yards on one play and 6 yards on another, you have lost a total of 9 yards.

25x=2544 what does x represent

Georgia [21]

Hey there!

Firstly, we are going to divide by $25$ on each of your sides because it paired off with a variable

Here's what I meant!

$\frac{25x}{25} = \frac{2,544}{25}$

We would have to cancel out the: $\frac{25x}{25}$ because it gives us $1$

Answer: $x = \frac{2,544}{25}$

Good luck on your assignment and enjoy your day!

It’s dividing by a factor of 10. So 30 divided by 10=3. You then do the same thing for the height. 300 divided by 10=30. The answer is 30.

5^(2x-1)+5^(x+1)=250<br> how do you solve?<br> thank you

Answer:

<em>x = 2</em>

Step-by-step explanation:

<u>Exponential Equations</u>

Solve:

$5^{2x-1}+5^{x+1}=250$

Separate each exponential:

$5^{2x}5^{-1}+5^{x}5^{1}=250$

Operating:

$\displaystyle \frac{5^{2x}}{5}+5^{x}5=250$

Multiplying by 5:

$5^{2x}+25\cdot5^x=1250$

Rearranging:

$5^{2x}+25\cdot5^x-1250=0$

Recall that:

$5^{2x}=(5^{x})^2$

$(5^{x})^2+25\cdot5^x-1250=0$

Calling

$y=5^{x}:$

$y^2+25y-1250=0$

Factoring:

$(y-25)(y+50)=0$

There are two possible solutions:

y=25

y=-50

Since

$y=5^{x}$

y cannot be negative, thus:

$5^{x}=25=5^2$

The solution is:

x = 2
