Answer:

$620

Step-by-step explanation:

Let the price of refridgerator be "r"

price of washer be "w"

and

price of dryer be "d"

Total 1800, that means, we can write:

r + w + d = 1800

Also, refrigerator cost 250 more than washer, so we can write:

r = w + 250

The dryer is HALF (0.5) of washer, so we can write:

d = 0.5w

Now, we replace equation1 with equation 2 & 3, so get an equation in "w" and solve for w:

r + w + d = 1800

w + 250 + w + 0.5w = 1800

2.5w + 250 = 1800

2.5w = 1800 - 250

2.5w = 1550

w = 1550/2.5

w = 620

Thus, the washer costed $620

Does anyone know the answer to this?
PolarNik [594]

Answer:

(B) The exponents should be subtracted by the quotient rule of exponents

Step-by-step explanation:

Let's examine how this was solved.

(\frac{4^2 4^3}{4^{-5}})^2

He first rose everything in the parentheses to the second power, which is just multiplying all the exponents by 2. This is correct.

\frac{4^4 4^6}{4^{-10}}

He then combined the numerator exponents. Exponent rules say that a^b \cdot a^c = a^b+c, so he should have ended up with 4^{10}, which he did. This is correct.

\frac{4^{10}}{4^{-10}}

Now, what he did in the final step is wrong. He added the exponents. However, exponent rules tell us that when we have \frac{a^b}{a^c}, it equals a^{b-c}.

10 - (-10) = 10+10 = 20

So the final answer should have been 4^{20}

Hope this helped!

writing an equation of a line given its slope and y-intercept. write an equation in slope-intercept form for the line with slope
Gre4nikov [31]

Answer:

y = -5(x-1)

Step-by-step explanation:

A y-intercept of 1 means that the point (0,1) falls on the line.

Slope-intercept form is y-y_{1} =m(x-x_{1} ) where m is the slope...

Therefore, the slope-intercept equation is y-1=-5(x-0) or y-1=-5x
