Question

compute.
$-3.46 + (-4.23) = square$
$-7.6 + 39.2 = square$

Explanation:

Step1: Simplify the first expression

$-3.46 + (-4.23) = -3.46 - 4.23$

Step2: Calculate first sum

$-(3.46 + 4.23) = -7.69$

Step3: Rearrange the second expression

$39.2 - 7.6$

Step4: Calculate second sum

$39.2 - 7.6 = 31.6$

Answer:

$-3.46 + (-4.23) = -7.69$
$-7.6 + 39.2 = 31.6$
