Question -4x - 9 = -13?

Mathematics
1 answer:

<em>X= 1.</em>

<em>For this expression to be correct, you would have to make sure that -4 stays -4. Any negative number subtracted by a positive number makes it go farther down into the negatives as a result even if the 9 is positive.</em>

<em>Hope this helps and have a nice day.</em>

I need help asap. I don’t know how to do this

Answer:

  10 in

Step-by-step explanation:

There are two ways to work this problem, and they give different answers. The reason for that is that <em>the data shown in the diagram is not consistent</em>.

<u>Method 1</u>

Use the area to determine the base length. The area formula is ...

  A = (1/2)bh

  20 in^2 = (1/2)(b)(4 in)

  (20 in^2)/(2 in) = b = 10 in

The missing side dimension is 10 inches.

__

<u>Method 2</u>

Use the Pythagorean theorem to find the parts of the base, then add them up.

Left of the "?" we have ...

  left^2 +4^ = 6^

  left^2 = 36 -16 = 20

  left = √20 = 2√5

Right of the "?" we have ...

  right^2 +4^2 = 8^2

  right^2 = 64 -16 = 48

  right = √48 = 4√3

So, the base length is ...

  base = left + right = 2√5 +4√3

  base ≈ 11.400 in

The missing side dimension is 11.4 inches. (The area is 22.8 in^2.)

A certain number exceeds 18 by as much as 44 exceed the number. What is the number?
asambeis [7]

Answer:

x=31  is the required number.

Step-by-step explanation:

Let the number be represented as "x".

Then, According to the statement given, "x" exceeds by as much as 44 exceed the number, then the equation can be written as:

⇒x-18=44-x

⇒x+x=44+18

⇒2x=62

⇒x=31

Hence, the required number is x =31.
