What is 12+24=2(6+ )

Lyrx [107]

Answer:

$\huge \boxed{x=12}$

Step-by-step explanation:

Let the unknown number be x.

12+24=2(6+x)

Switch sides.

2(6+x)=12+24

Expand brackets.

12+2x=12+24

Subtract 12 from both sides of the equation.

12+2x-12=12+24-12

2x=24

Divide both sides of the equation by 2.

(2x)/2=24/2

x=12

An angle measures 6º less than the measure of its complementary angle. What is the

vesna_86 [32]

Answer:

The measure of each angle is:

48° y 42°

Step-by-step explanation:

Complemenary angles sum 90°

then:

a + b = 90°

a = b - 6

∴

(b-6) + b = 90

2b - 6 = 90

2b = 90+6

2b = 96

b = 96/2

b = 48°

a = b-6

a = 48 - 6

a = 42°

Check:

42° + 48° = 90°
