Can someone please help with my maths homework? I need to estimate the value of 102.3 / 4.7

2 answers:

6 0

The answer would be 20.

102.3 can be rounded down to 100 and 4.7 can be rounded up to 5. 100 divides by 5 is 20.

The trick is to find the 2 closest numbers that you can do mental math with.

OK - convert the 2 numbers to one significant figure:-

102.3 = 100
4.7 = 5

So the estimate is 100/5 = 20 answer

Answer:

The solution to the inequality is:

$x$

The number line solution graph is also attached below.

Step-by-step explanation:

Given the inequality

$2(x-3)-8< -4$

Add 8 to both sides

$2\left(x-3\right)-8+8$

$2\left(x-3\right)$

Divide both sides by 2

$\frac{2\left(x-3\right)}{2}$

$x-3$

Add 3 to both sides

$x-3+3$

$x$

Thus, the solution to the inequality is:

$x$

The number line solution graph is also attached below.
