Please help me I need help with my test review I can’t figure out m<1 and m<2

aksik [14]

Answer:

m1=12 and m2=168

Step-by-step explanation:

$m1 + m2 = 180 \: (straight \: angle) \\ then \\ x - 12 + 7x = 180 \\ 8x - 12 = 180 \\ 8x = 180 + 12 = 192 \\ x = 192\div 8 \\ x = 24\\ hence \\ m1 = 24 - 12 = 12 \\ m2 = 7 \times 24 = 168.$

2) -2(7n – 6) +n=-3 - 8n

iogann1982 [59]

Answer and Step-by-step explanation:

For this equation the answer is : $n=3$

Step 1 : Simplify both the sides of the equation :

$-2(7n-6)+n=-3-8n$

$(-2)(7n)+(-2)(-6)+n=-3+-8n$ (Distribute)

$-14n+12+n=-3+-8n$

$(-14n+n)+(12)=-8n-3$ (Combine the like terms)

$-13n+12=-8n-3$

Step 2 : Add " $8n$ " to both the sides :

$-13n+12+8n=-8n-3+8n$

$-5n+12=-3$

Step 3 : Subtract " $12$ " from both the sides :

$-5n+12-12=-3-12$

$-5n=-15$

Step 4 : Divide both the sides by " $-5$ "

$\frac{-5n}{-5} =\frac{-15}{-5}$

$n=3$

That's your final answer : $n=3$
