what does x equal?

Answer 1

Answer:

8

Step-by-step explanation:

3x8=24-4=20

Hope this helps!

Answer 2

Answer:

Look down below!

Step-by-step explanation:

Alright, so let's start solving this

1. First we are going to be placing the x one one side and the constants (or the regular numbers) on the other side.

How to do that?

Well, we can take -3x and 20 to their other sides.

The reason for this is that we don't want to have the value with x as a negative

So we do

-3x-4 = 20

+3x -20 -20+3x

You may not understand what was about but all I did was just added 3x to both sides and subtracted 20 to both sides to make the new equation

-24 = 3x or 3x = -24

Now we can see that the x has a number it is being multiplied with so to get rid of the number we divide everything by 3

So

3x/3 = -24/3

Which results in x = -8 and voila, there is your answer!

B 13.93 yd
C. 144 ya
D. 12 yd

Answers

Answer:

12

Step-by-step explanation:

For these problems you should use the pythagorean theorem: a^2+b^2=c^2

In this case, 13=c and 5=a

so:

5^2+x^2=13^2

25+x^2=169

subtract 25 from both sides

x^2=144

√144=12

missing side=12

the answer is 12 yards

Grocery Store A is selling bananas for $0.75 for 12 pound. Grocery Store B is selling 5 pounds of bananas for $3.75.
Which store is offering the best unit rate? Show your work

Answers

Answer:

12 ×$0.75 =$8.00

3.75 ÷ 5 = $1.33 a pound,

$1.33 × 12 = $15.96 so store A is offering the best rate.

It is found that Store B is offering the best unit rate for the bananas.

What is unit rate?

There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.

Given that Grocery Store A is selling bananas 1/2 pound for $0.75 .

Grocery Store B is selling 5 pounds of bananas for $3.75.

According to the question,

Store A is selling bananas 1/2 pound for $0.75 .

Therefore,

For one pound will be;

= 0.75/0.5

= 1.5

And store B is selling 5 pounds of bananas for; $3.75

Therefore,

One pound will cost;

3.75/ 5 = 0.75

Hence, Store B is offering the best unit rate for the bananas.

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 4,335 square feet. The width of the basement is
3/5 its length. What is the length of Louis's basement? The length is blank feet.

Answers

Answer:

The length of Louis's basement is 85 feet.

Step-by-step explanation:

The area of the basement, A = 4,335 square feet

The width of the basement is  3/5 its length.

Let length be l.

Width = (3/5)l

The area of the basement is given by :

[tex]A=l\times b\\\\4,335 =l\times \dfrac{3}{5}l\\\\4,335 =\dfrac{3}{5}l^2\\\\l^2=\dfrac{4,335 \times 5}{3}\\\\l=\sqrt{\dfrac{4335\times5}{3}}\\\\l=85\ ft[/tex]

So, the length of Louis's basement is 85 feet.

What is the probability of rolling a six on a fair die?

Answers

Answer: 1/6

Step-by-step explanation: To find the probability of rolling a six,

let's use our ratio for the probability of an event.

number of favorable outcomes / total number of outcomes

Since only one side of a die has a six on on it, the number of favorable

outcomes for rolling a six is 1 and since there are six sides to a die and it's

equally likely that the die will landy on any of these sides, the total number

of outcomes is 6.

So the probability of rolling a six is 1/6.
