A winning football team more than doubled. The offensive yards gained by its opponent. The opponent gained 272 offensive yards.

Daniel [21]

Answer:

$80x>2*272$

More than 6.8 yards per game.

Step-by-step explanation:

Let x be the possible number of yards per play for the winning team.

We have been given that the winning team had 80 offensive plays, so the number of possible yards in 80 offensive plays will be 80x.

We have been given that a winning football team more than doubled the offensive yards gained by its opponent.

We can represents this information in an inequality as:

$80x>2*272$

Therefore, the inequality $80x>2*272$ can be used to find the possible number of x of yards per play for the winning team.

Let us solve for x.

$80x>544$

Let us divide both sides of our inequality by 80.

$\frac{80x}{80}>\frac{544}{80}$

$x>6.8$

Therefore, the winning team will score more than 6.8 yards per play.

The track team is trying to reduce their time for a relay race. First they reduce their time by 2.1 minutes. Then they are able

klemol [59]

Answer: 15.7 minutes

Step-by-step explanation:

Let x be the time in the beginning (in minutes).

Given: The track team is trying to reduce their time for a relay race.

First they reduce their time by 2.1 minutes.

Then they are able to reduce that time by 10

If their final time is 3.96 minutes, then

x-t1-t2= 3.6
x= 3.6+ t1+ t2
x= 3.6+ 2.1+ 10
x= 15.7

Hence, their beginning time was 15.7 minutes.

What’s the square root of -121

irakobra [83]

The answer is 11 i

<em /><em>Explanation:
</em>
The square root needs to be a number that can be multiplied by itself and equal the original number.

In this case, the number is 11, 11*11 = 121

However, you are looking for the square root of a negative number, due to this you would add i to the answer,
i = imaginary number, or -

( Depending on your grade/ teacher however, you can put "no solution"

I need to solve this system of equations, how do I do that?<br> 3x-4y=20<br> y=3/4x-5

Paha777 [63]

Answer:

Is is Infinitely many solutions so 0=0

<em><u>Step-by-step explanation:</u></em>

<h3>First we have to rearrange/simplify the equations:</h3>

Equation 1: 4y - 3x = -20

Equation (2): y - 3x/4 = -5

<h3>Then you remove the fractions by multiplication: </h3>

Multiply equation (2) by 4

<h3>The Equations now look like this: </h3>

Equation 1: 4y - 3x = -20

Equation (2): 4y - 3x = -20

<h3>Solve for y on Equation (2):</h3>

y = <u><em>3x/4 - 5</em></u>

<h3>Then plug in this for the y in Equation 1 and then solve:</h3>

4•(<u><em>3x/4-5</em></u>) - 3x = -20

Therefore the answer leads to:

Infinitely many solutions, 0=0

Hope this helped :')
