Round off 3. 55 to one significant figure

Anika [276]

Answer:

3.6

Step-by-step explanation:

We must first clarify how a number is rounded.

To round a number to unity we have to look at the first number after the comma.

If this number is less than 5 (1, 2, 3, 4) we should not do anything, but if that number is 5 or greater (5, 6, 7, 8, 9) we must add a unit to the number.

That is to say:

<5 do nothing

=> 5 round to the next number (+1)

So in the case of 3.55 it would be.

3.55 = 3.6

What is... X/2 - 13 = 1

kow [346]

X ÷ 2 - 13 = 1
Write the division as a fraction
$\frac{1}{2}x - 13 = 1$
Multiple both sides of the equation by 2
$2 \times \frac{1}{2}x \times - 2 \times 13 = 12$
Reduce the number with greatest common divisor 2
$x - 2 \times 3 = 2$
Multiply the numbers
$- 2 \times 13$
Then u will have
$x - 26 = 2$
Move constant to the right by adding its opposite sides
$x - 26 + 26 = 2 + 26$
Eliminate the opposites
$- 26 + 26$
Then you have
$x = 2 + 26$
Add the numbers
$x = 28$
