On number 3 you multiply the number on the outside of the “( )” by the numbers on the inside of the “( )” so 0.5(12m)-0.5(22n)

Number 4 you do the same... 2/3(18x)+2/3(6z) then you multiply those and then add the answers together.

What's the answer to this math picture please?

professor190 [17]

Answer:

m<BGC = 145°

Step-by-step explanation:

<AGC and <DGB are vertical angles. Vertical angles are congruent. Therefore:

m<AGC = m<DGB

$3x + 20 = 8x - 5$ (substitution)

Collect like terms

$3x - 8x = -20 - 5$

$-5x = -25$

Divide both sides by -5

x = 5

m<BGC = 180 - (m<AGC) (linear pair)

m<BGC = 180 - (3x + 20)

Plug in the value of x

m<BGC = 180 - (3(5) + 20) = 180 - 35

m<BGC = 145°
