Find the value of |-4 + 3| · 8.
Kay [80]

Answer:

20

----------------------------------------------------------------------------------------------------------

<h3>Solve</h3>

Any negative number added to a positive number always brings you further to the left, which is considered the negative zone. It's more like subtracting in a different way. That said, let's make the equation.

-4 = -4<em> </em>

Now, multiply 3 by 8.

3 * 8 = 24

Add negative 4, meaning subtract 4 in a dynamic way.

|-4 + 24~| = 20

Aiden borrows a book from a public library. He read a few pages on day one. On day two, he reads twice the number of pages than
Fofino [41]

Let the number of pages read on day 1 be = x

Then on day 2 he read twice the pages from day one, it is = 2x

On 3rd day he read 6 pages less than 1st day, it is = x-6

Total pages are = 458

The equation becomes: x+2x+x-6=458

4x-6=458

4x=464

x=116

So on the third day, Aiden read x-6=116-6=110 pages.
