(x - 2 < 5) ∩ (x + 7 > 6)

Let's resolve each one

x - 2 < 5

x < 5 + 2

x < 7

x + 7 > 6

x > 6 - 7

x > -1

So we have 2 conditions: x > -1 and x < 7 plus, we need the values that's equal in x < 7 and x > -1 because we have an intersection

S = {x e R / -1 < x < 7}

What is 7/25 in decimal form
timama [110]

Every fraction is just a short way to write a division.
Whenever you see a fraction, it means

            the top number
divided by
            the bottom number.

When you actually do the division, like with a pencil or a calculator,
the quotient you get is the decimal form of the fraction.

I won't insult your intelligence by giving you  7  divided by  25 .
I'm sure you can do that easily.

I also won't insult your intelligence by sending you to a web site.
I assume that if you were on a desert island without your phone
or any 4G coverage, you'd be able to figure out a way to divide
7 by 25.
