Answer: Parallel lines are marked with "feathers". Notice how they appear assets: the lines with one feather are parallels, and the lines with two feathers are parallel. A "box" at the point of intersection indicates the lines are perpendicular.
I found this on the web, maybe it will help you. Sorry if you still don't understand.
She can get 21 portions. Since 2/3 and 42/3 already share the same denominator, all you need to do is divide 42 by 2 to get 21.
Answer:
x= 20,y= −36
Step-by-step explanation:
3x+2y=−12
2x+y=4
Subtract 2x
from both sides of the equation.
y=4−2x
3x+2y=−12
Replace all occurrences of y
with 4−2x
in each equation.
Tap for more steps...
−x+8=−12
y=4−2x
Solve for x
in −x+8=−12
.
Tap for more steps...
x=20
y=4−2x
Replace all occurrences of x
with 20
in each equation.
Tap for more steps...
y=−36
x=20
