Answer:
r=7
Step-by-step explanation:
6r-7+90+55=180
6r+138=180 ----- 6r=180-138
6r=42 ----- divide both sides by 6
r=7
(We get the 90 from the 90degrees in the middle of this supplementary angle and the total, 180, from the straight angle made from all three angles.)
hope this helps!

Answer:
17
Step-by-step explanation:
5-4b ; b=-3
- substitute b= -3 into the expression
5-4×(-3)
- multiply the numbers
(-4×(-3)=+12) 5+12
- add the numbers
(5+12=17)
SOLUTION: 17
Answer: (this is solving for m)
m= −4
/7
n + −8
/7
Step-by-step explanation:
7m + 4n + 8+ −4n =0 + −4n
7m + 8= −4n
7m + 8 + −8 = −4n + −8
7m = −4n − 8
7m
/7 = (−4n − 8 )
/7
m= −4
/7
n + −8
/7
