So what would happen is that y is always the same, so if y is 2, then it will always be 2, however x does change. this is called a zero or no slope. Happy Valentines!

I need help finding our the perimeter

barxatty [35]

Answer:

11x + 10y - 2w

Step-by-step explanation:

Hello!

To solve for the perimeter, we add up the like terms.

What are like terms?

Like terms are terms with the same variable and degree. 4x and 5y are NOT like terms because the variable is not the same. However, 4x and 3x are like terms, as adding them gives us 7x.

4x and 4x² are not like terms, because the degree of 4x is 1 (degree means the largest exponent), but the degree of 4x² is 2.

Solve for Perimeter:

Combine the like terms by adding them up.

Perimeter = (8x - 4w) + (3y + 2w) + (3x + 7y)
P = 8x - 4w + 3y + 2w + 3x + 7y
P = 8x + 3x + 3y + 7y - 4w + 2w
P = 11x + 10y - 2w

The perimeter is 11x + 10y - 2w

A company that offers tubing trips down a river rents tubes for a person to use for $20 and “cooler” tubes to carry food and wat

aivan3 [116]

The group rent 11 river rent tubes and 4 cooler tubes.

Step-by-step explanation:

Rent for river rent tube = $20

Rent for cooler tubes = $12.50

Total spent = $270

Total tubes rented = 15

Let,

x be the number of river rent tube.

y be the number of cooler tubes.

According to given statement;

x+y=15 Eqn 1

20x+12.50y=270 Eqn 2

Multiplying Eqn 1 by 20

$20(x+y=15)\\20x+20y=300\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(20x+20y)-(20x+12.50y)=300-270\\20x+20y-20x-12.50y=30\\7.50y=30$

Dividing both sides by 7.5

$\frac{7.5y}{7.5}=\frac{30}{7.5}\\y=4$

Putting y=4 in Eqn 1

$x+4=15\\x=15-4\\x=11$

The group rent 11 river rent tubes and 4 cooler tubes.

Dhani has 4 cards numbered 1 through 4. He removes 2 cards at random and adds their values.

DanielleElmas [232]

Answer:

$2/3$

Step-by-step explanation:

The total number of sums (not distinct) is $4\cdot 3=12$ , because we're removing without replacement.

Count the sums that fit the stipulation (sum $\leq$ 5):

$1,2,\\2,1\\1,3\\3,1\\1, 4\\4, 1\\2, 3, \\3,2$

There are 8 sums that work. Therefore, the desired answer is $\frac{8}{12}=\boxed{\frac{2}{3}}$
