Answer:
90ml
Step-by-step explanation:
all we need to do is find 60% of 150
60% of 150 is 90
This is a system of equation:
7y - 5x = 31
x = 4 - 2y
Plug in 4 - 2y for x
7y - 5(4 - 2y) = 31
Distribute -5 to both 4 and -2y
7y - 20 + 10y = 31
Simplify
17y - 20 = 31
Isolate the y. Note the equal sign. What you do to one side you do to the other. Do the opposite of PEMDAS.
Add 20 to both sides
17y - 20 (+20) = 31 (+20)
17y = 51
Divide 17 from both sides to isolate the y
17y/17 = 51/17
y = 51/17 or 3
y = 3
-------------------------------------------------------------------------------------------------------------------
Plug in 3 for y in one of the equations.
x=4−2y
x = 4 - 2(3)
Simplify.
x = 4 - 6
x = -2
-------------------------------------------------------------------------------------------------------------------
x = -2, y = 3 is your answer, or B)
-------------------------------------------------------------------------------------------------------------------

Answer:
(x -t -250)/2
Step-by-step explanation:
The amount left from x after paying t and 250 is ...
x -t -250
If this is split into two equal parts, each share is ...
share = (x -t -250)/2
