Answer:
m = (n/3) - k
Step-by-step explanation:
n = 3(k + m)
n = 3k + 3m
n - 3k = 3m
3m/3 = (n - 3k)/3
m = (n/3) - k
Answer:
5:15

Answer:
170
Step-by-step explanation:
A heptagon's internal angles add up to 900 degrees.
So:
(2x-13)+(3x-8)+(2x-3)+(2x-7)+(3x-1)+(2x+11)+(2x+9) = 900
16x - 12 = 900
16x = 912
x = 912/16
x = 57
So:
3x - 1 = 3 * 57 -1 = 170
Answer:
Greg is 19 and Teri is 11
Step-by-step explanation:
Greg = g
Teri = t
-------------
Formulas:
2t-3= g
g+t = 30
Answer:
g = 19
t = 11
Check:
2(11)-3 = 19
19 + 11 = 30
Y=2x-2
I have done this in my head on the spot so I would test it on a graph .
