A washer and a dryer cost $959 combined. The washer costs $59 more than the dryer. What is the cost of the dryer?
dem82 [27]

Answer:

A dryer costs $450.

A washer costs $509.

Step-by-step explanation:

Let:

"washer" = x

"dryer" = y

Set the equations:

x + y = 959

x = y + 59

First, plug in y + 59 for x in the first equation for x:

x + y = 959

(y + 59) + y = 959

Simplify, combine like terms:

y + y + 59 = 959

2y + 59 = 959

Next, isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis, Exponents (& Roots), Multiplications, Divisions, Additions, Subtractions.

First, subtract 59 from both sides of the equation:

2y + 59 (-59) = 959 (-59)

2y = 959 - 59

2y = 900

Next, divide 2 from both sides of the equation:

(2y)/2 = (900)/2

y = 900/2

y = 450

Next, plug in 450 for y in one of the equations:

x = y + 59

x = (450) + 59

x = 509

Check:

x + y = 959

450 + 509 = 959

959 = 959 (True).

Does this graph represent a function? why or why not?
AVprozaik [17]

Answer:

D. Yes, because it passes the vertical line test

Step-by-step explanation:

the vertical line test is a test you do by drawing a vertical line through the graph of the function if more than one point from the function lies on the line it does not represent a function

in this graph at any part if you draw a vertical line it passes through one point only

A box has three balls, one white and two red. We select one ball, put it back in the box, and select a second ball (sampling wit
Dennis_Churaev [7]

Answer:

See explaation

Step-by-step explanation:

Given

Represent the balls with the first letters

W =1

R =2

Solving (a): P(F) --- White balls twice

The event of F is:

F = \{(W,W)\}

So:

P(F) = P(W) * P(W)

P(F) = \frac{n(W)}{n} * \frac{n(W)}{n}

P(F) = \frac{1}{3} * \frac{1}{3}

P(F) = \frac{1}{9}

Solving (b): P(G) --- two different colors

The event of G is:

G = \{(W,R),(R,W)\}

So:

P(G) = P(W) * P(R) + P(R) * P(W)

P(G) = \frac{n(W)}{n} * \frac{n(R)}{n} + \frac{n(R)}{n} * \frac{n(W)}{n}

P(G) = \frac{1}{3} * \frac{2}{3} + \frac{2}{3} * \frac{1}{3}

P(G) = \frac{2}{9} + \frac{2}{9}

P(G) = \frac{4}{9}

Solving (c): P(H) --- White picked first

The event of H is:

H = \{(W,R),(W,W)\}

So:

P(H) = P(W) * P(R) + P(W) * P(W)

P(H) = \frac{n(W)}{n} * \frac{n(R)}{n} + \frac{n(W)}{n} * \frac{n(W)}{n}

P(H) = \frac{1}{3} * \frac{2}{3} + \frac{1}{3} * \frac{1}{3}

P(H) = \frac{2}{9} + \frac{1}{9}

P(H) = \frac{3}{9}

P(H) = \frac{1}{3}

Solving (d): F and G, mutually exclusive?

We have:

F = \{(W,W)\}

G = \{(W,R),(R,W)\}

Check for common elements

n(F\ n\ G) = 0

<em>Hence, F and G are mutually exclusive</em>

Solving (e): G and G, mutually exclusive?

We have:

G = \{(W,R),(R,W)\}

H = \{(W,R),(W,W)\}

Check for common elements

n(G\ n\ H) = 1

<em>Hence, F and G are not mutually exclusive</em>
