Answer

$3

Step-by-step explanation:

To find the x value, you want to cancel out the y terms in the equations. To do so, multiply (2x+5y=6) by 2, and (-x+2y=-3) by -5. This gives you

4x+10y=12

5x-10y=15

You can then cancel out the y terms and add the other terms from the 2 equations together to make

9x=27

You then divide 27 by 9 to get 3 as the value for x.

The royals softball team played 75 games and won 55 of them. What percent of the games did they lose (round to the nearest hundr
dimaraw [331]
If they won 55 of the games, that means they lost the rest of the 75.  So,
75 - 55 = 20 games lost.  To find the percentage of 20 out of 75, you set up a proportion:

\frac{20}{75}=\frac{x}{100}

where x = the percentage of games lost.  Cross multiply and divide to isolate the x:

\frac{20}{75}=\frac{x}{100}\\75x=2000\\75x/75=2000/75\\x=26.6666667

Rounded to the nearest hundredth, the Royals lost 26.667 % of their games.

Hey, could you please answer this question? My time is running out. A bicycle rental shop has a two tier pricing system based on
erastova [34]

Answer:

3.93 per hour

Step-by-step explanation:

The first 4 hours is at 20 hours / 4 hours  or 5 dollars an hours

The second  line has a slope of 2.50 dollars an hour

But there is also a surcharge when you go over 4 hours

That is a 5 dollar flat rate at 4 hours

Assuming that we do not include the flat rate in the hourly calculation

4 hours * 5 dollar + 3 hours * 2.50 = 20+7.50

27.50 is the hourly charge

Divide by 7 hours

3.928571429

3.93 per hour

Myesha finds some nickels and quarters under the couch cushions. How many coins does she have if she has 6 nickels and 12 quarte
Advocard [28]

If Myesha found 6 nickels and 12 quarters under her cushion, this means that she has a total of 18 coins.

<h3>What is an equation?</h3>

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the number of nickels and y represent the number of quarters. There are 2 cups in 1 pint. Hence:

If she has 6 nickels and 12 quarters:

Number of coins = 12 + 6  = 18

If she has x nickels and y quarters:

Number of coins = x + y  

If Myesha has 6 nickels and 12 quarters, this means that she has 18 coins.

Which is the equation of a hyperbola centered at the origin with y-intercepts +12 -12, and asymptote y=3x/2
dangina [55]

Answer:

\frac{y^2}{144}-\frac{x^2}{64}=1

Step-by-step explanation:

The equation of a hyperbola centered at the origin with vertices on the y-axis is given by: \frac{y^2}{a^2}-\frac{x^2}{b^2}=1

The vertices of the hyperbola are the y-intercepts (0,12) and (0,-12)

This implies that:

2a=|12--12|

2a=24

a=12

The asymptote equation of a hyperbola is given by:

y=\pm\frac{a}{b}x

The given hyperbola has asymptote: y=\pm\frac{3}{2} x

By comparison; \frac{a}{b}=\frac{3}{2}

\implies \frac{12}{b}=\frac{12}{8}

\implies b=8

The required equation is:

\frac{y^2}{12^2}-\frac{x^2}{8^2}=1

Or

\frac{y^2}{144}-\frac{x^2}{64}=1
