1) collect like terms
28tu+(49t+9t-t)
2) simplify
28tu+57t
Answer: 28tu+57tu
Answer:
23-5= 18
Step-by-step explanation:
Answer:
y = 1.2x - 3 (slope intercept form)
or
5y-6x = -15 (standard form)
Step-by-step explanation:
Two parallel lines have the same slope, which means that our line's slope, will also be 1.2.
we can use the formula to find the equation of the line:
y-y1 = m (x-x1)
y1 - y coordinate of a point on the line
x1 - x coordinate of the same point on the line
m - slope
and we get:
y+3 = 1.2 (x-0)
y = 1.2x - 3 (slope intercept form)
or
5y-6x = -15 (standard form)
For this case, the first thing we must do is define variables:
x: students of group 1
y: students of group 2
We now write the system of equations that models the problem:

Solving the system by substitution we have:



Then, the value of y is given by:

Answer:
8 students of group 1
20 students of group 2
