(3*4)+(1*7)/7*4 = 12+7/28 = 19/28
your answer is 19/28
2 students more were introducced in the class and each group had 8 people
X + y = 22
x = 2y + 3
this would be ur system of equations
Answer:
Examination of the equation shows (graph):
x = 0, y = .5
Then .5 = c gives us the value of c giving
y = m x + .5 is our equation
Using y = 0, x = -1 gives
o = -1 * m + .5
m = .5
y = .5 x + .5 for the final equation
Check:
At x = 5, y = 3
3 = .5 (5) + .5 = 3
