A washer and a dryer cost $995 combined. The washer cost $95 more than the dryer. What is the cost of the dryer?

Step-by-step explanation:

Dryer = x

Washer: x+95

Now to find x, we must create an equation.

x+(x+95)=995

Now, we can add the variables.

x+x=2x

So now it would be:

2x+95=995

Now we must solve, since there is only one variable, we need to solve the constants.

Since 95 is positive, we need to cancel it out. And since you did it to one constant, you need to do it to the other.

2x=900

(since you subtract 95 from the other constant, too.)

Now, you must divide both sides by 2.

x = 450.

Now the washer isn't what we're supposed to find, but technically, you would still need it in the problem to find the answer for the dryer.

Hope this helps!

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
