The reason is because she didn't survey the school, but only surveyed her class, and to add to that It didn't say it was a random selection of students. Juliet concludes that short stories is the favorite type of book of the students in her school because 80% of the students in her class like short stories. Just because most of her class chose short stories she believes the rest of the school will have the same choice.

A washer and dryer cost $793 combined, the washer costs $93 more than the dryer. What is the cost of the dryer?
frosja888 [35]
The dryer costs x.
The washer costs $93 more than the dryer, so it costs x+93.
The washer and the dryer cost $793 altogether.

x+x+93=793 \\
2x=793-93 \\
2x=700 \\
x=\frac{700}{2} \\
x=350

The cost of the dryer is $350.

Ares of a rectangular floor of your house is Ax+5x-2. if the length is x+2 units, find A​
Snezhnost [94]

Answer:

A=4.

Step-by-step explanation:

Note: In the expression of area the first term should be Ax^2.

It is given that area of a rectangular floor of your house is Ax^2+5x-2 and the length is (x+2) units.

We know that, area of a rectangle is

Area=length\times width

Since length of the rectangle is (x+2), therefore (x+2) is a factor of Ax^2+5x-2 and the value of Ax^2+5x-2 is 0 at x=-2.

A(-2)^2+5(-2)-2=0

4A-10-2=0

4A-12=0

4A=12

Divide both sides by 4.

A=4

Therefore, the value of A is 4.

Solve using substitution or elimination.<br><br> y = x + 1<br> 2x - 5y = 4
andrew-mc [135]

Substitute y = x + 1 into 2x - 5y = 4

-3x - 5 = 4

Solve for x in -3x - 5 = 4

x = -3

Substitute x = -3 into y = x + 1

y = -2

Therefore,

<u>x = -3</u>

<u>y = -2</u>
