When 0.3(4x – 8) – 0.5(–2.4x + 4) is simplified, what is the resulting expressions

lisabon 2012 [21]

Answer:

$2.4x-4.4$

Step-by-step explanation:

Given the following question:

$0.3(4x-8)-0.5(-2.4x+4)$

To simplify the expression, we are going to need to rewrite the expression by expanding the terms and then solve by using the distributive property. Then we combine like terms in till the expression can no longer be simplified to find our answer.

$0.3(4x-8)-0.5(-2.4x+4)$
$0.3(4x-8)$
$0.3\times4=1.2x$
$0.3\times4=2.4$
$1.2x-1.2-0.5(-2.4x+4)$
$-0.5(-2.4x+4)$
$-0.5\times-2.4=1.2$
$-0.5\times4=-2$
$1.2-2$
$1.2x-2.4+1.2x-2$
$1.2+1.2=2.4x$
$-2.4+-2=-4.4$
$=2.4x-4.4$

Your answer is "2.4x - 4.4."

Hope this helps.

Angle B measures 60°. What is the measure of the angle that is complementary to angle B?

vodomira [7]

Complementary angles add up to 90.
Say the complementary angle is A.
Angle A + Angle B = 90
Angle A + 60 = 90
Angle A = 30 degrees

Hope this helps :)
