Answer: y = 15
Step-by-step explanation:
6y - 10 + 6y + 10 = 180
+ 10 - 10 -10 +10
12y = 180
12y/12 = 180/12
y = 15
Answer:
m = 
Step-by-step explanation:
Given
y = mx + b ( isolate the term in m by subtracting b from both sides )
y - b = mx ( divide both sides by x )
= m
8
46
is equivalent to 4
23
because 4 x 2 = 8 and 23 x 2 = 46
12
69
is equivalent to 4
23
because 4 x 3 = 12 and 23 x 3 = 69
16
92
is equivalent to 4
23
because 4 x 4 = 16 and 23 x 4 = 92
A^2+b^2=c^2
35^2+25^2=25^2
So the answer is 25
