6(2x-8)+3=15
12x-48+3=15 Distribute the 6
12x-45=15 Add (-48) and (3)
12x=60 Add 45 to both sides
x=5 Divide both sides by 12

Distribute.
6 times 2x= 12x
6 times 8= 48
12x+48+3=15
12x+51=15
subtract 51 from both sides.
12x=-36
divide by 12 on each side
-3=x

Overview

Alisiya [41]

Answer:

125.4

Step-by-step explanation:

Given

$Number = 125.3546$

Required

Round to 1 decimal place

Up till the first decimal place, the number is:

$Number = 125.3$

The digit after .3 is 5

The conditions for approximation are:

If n > 4, approximate to 1

Else: approximate to 0

In this case: 5 > 4, so we approximate to 1

Add this "1" to the last digit of 125.3. This becomes 125.4

<em>Hence: when the number is approximated to 1 decimal place, the digit is 125.4</em>
