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

Answers

Answer 1

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).

~

Answer 2

Answer:

$450

Step-by-step explanation:

1. First, let's make a system of equations:

[tex]y+59=x,x+y=959[/tex] (y = dryer, x = washer)

2. (Solving)

Solve y + 59 = x for y:

[tex]y + 59 = x[/tex] [tex]y + 59-59=x-59[/tex] (Subtract 59 from both sides)[tex]y = x-59[/tex]

Substitute x - 59 for y in x + y = 959

[tex]x + y = 959[/tex] [tex]x+x-59=959[/tex] [tex]2x - 59 = 959[/tex] [tex]2x - 59 + 59 = 959 + 59[/tex] (Add 59 to both sides)[tex]2x = 1018[/tex] [tex]\frac{2x}{2} = \frac{1018}{2}[/tex] (divide both sides by 2)[tex]x = 509[/tex]

Substitute 509 for x in y = x - 59

[tex]y = x - 59[/tex] [tex]y = 509-59[/tex] [tex]y = 450[/tex]

Therefore, the dryer costs $450. (The washer costs $509).

f(x) = (x + 2)(x - 1)(x + 7)

f(x) = (x + 14)(x - 8)(x + 5)

When graphing data from a study the scale of the data:

A, may make the data misleading
B, should always be presented using a factor of 2.
C, is not important.
D, will not change how the data appears.

Answers

Answer:

B

Step-by-step explanation:

B no steps needed to do this

The scale factor enlarges or reduces the graph of the data set thus it will not change the shape thus option (D) is correct.

What is a graph?

A graph is a diametrical representation of any function between the dependent and independent variables.

The graph is easy to understand the behavior of the graph.

The scale factor is used to enlarge any data set by the same multiplier.

For example, a coordinate (x,y) will be enlarged by (9x,9y) so 9 will be the scale factor.

The scale factor is useful to work with data which not lie in the range of the given axis in coordinate geometry.

When we apply the scale factor it will either enlarge or reduce the plot size but the shape will remain the same so the data representation will be the same.

Hence "The scale factor enlarges or reduces the graph of the data set thus it will not change the shape".

Using the simple interest formula:

r = interest rate = 6% or 0.06
t = time = 60 days or 2/12 months

Substitute the given values into the formula:

I = P • r• t
I = $400 • 0.06 • 2/12
I = $4

Therefore, the student pays $4 in interest if the loan is paid back within 60 days.
