Answer:

<h2>1.5</h2>

Step-by-step explanation:

$-----------------------------$

$Here's$ $how$ $we$ $solve$ $the$ equation

$-1.2\left(3-x\right)$ = $-1.8$

$-1.2\left(3-1.5\right)$ = $-1.8$

$-3.6+1.2\cdot1.5$ = $-1.8$

$1.2\cdot1.5$ = $-1.8$

$-----------------------------$

5 . x^2 /x^2 for x=2

goblinko [34]

Answer:

1

Step-by-step explanation:

Hello!

Plug in 2 for x and simplify.

<h3>Evaluate</h3>

$\frac{x^2}{x^2}$
$\frac{2^2}{2^2}$
$\frac44$
$1$

We could have also simplified the fraction first. If a fraction has the same number in the numerator and the denominator, then it is always equal to 1, no matter what values of x.
