At the holiday valley ski resort, skis cost $16 to rent and snowboards cost $19. If 28 people rented on a certain day and the re

trapecia [35]

Answer:

$18$ skis and $10$ snowboards were rented.

Step-by-step explanation:

Let the number of skis rented be $x$ and the number of snowboards rented be $y$ .

If a total of $28$ people rented on a certain day, then the total number of skis and snowboards rented that particular day is also $28$ .

This gives us the equation

$x+y=28...eqn(1)$ .

If skis cost $ $16$ , then $x$ number of skis cost $ $16x$ .

If snowboards cost $ $19$ , then $y$ number of snowboards cost $ $19y$ .

The total cost will give us another equation,

$16x+19y=478...eqn(2)$

From equation (1),

$y=28-x...eqn(3)$ .

We put equation (3) into equation (2) to get,

$16x+19(28-x)=478$

We expand the brackets to obtain,

$16x+532-19x=478$

We group like terms to get,

$16x-19x=478-532$

This implies that,

$-3x=-54$

We divide both sides by $-3$ to get,

$x=18$

We put $x=18$ into equation (3) to get,

$y=28-18$

$y=10$

Therefore $18$ skis and $10$ snowboards were rented.

katrin2010 [14]

Answer:

How to Round to the Nearest Feet (Step-by-Step)?

First and foremost, identify the given feet number.

Now, look at the digit that we have to round off which is the first digit after the decimal point.

If that value is between 0 to 4, then leave the digit we care for and trim all digits to the right.

If p = 10 - 3y, work out p when =-10

adell [148]

Hello.

Plug in the value of p:

$\mathrm{-10=10-3y}$

Now, all we have to do is solve the equation for y.

First, let's add 10 to both sides:

$\mathrm{-10+10=10+10-3y}$

$\mathrm{0=20-3y}$

Now, add 3y to both sides:

$\mathrm{3y=20}$

Divide both sides by 3:

$\Large\boxed{y=\frac{20}{3} }$

I hope it helps.

Have a nice day.
