Answer:
y=8
Step-by-step explanation:
the sum of the three angles is 180
57 + 90 + 5y-7 = 180
5y + 140 = 180
5y = 40
y = 8
Answer:
Y = Mx+C (General equation of a straight line)
Step-by-step explanation:
From the data given above, we could deduce that the data has two coefficients (X and Y). The numbers could be used to generate equation of a straight line.
E.g 2x+4 = 5y which is equivalent to
Mx+C = Y
Where C is the constant.
The answer is
14
87
14
2
87
14
In a row
-12x = -48
-12x/-12 = -48/-12
x = 4
hope this helps
