Answer:
x=3, y=0.8
Step-by-step explanation:
8x+5y=28
4x+5y=16
Subtract the second simultaneous equation from the first.
You are left with: 4x=12
12/4=3
x=3
Substitute this back into one of the equations.
8(3)+5y=28
8*3=24
28-24=4
4=5y
4/5=0.8
y=0.8

Answer:
(x + 5) /2
Step-by-step explanation:
"a number" (this will represent as "x")
"increased" another way to say add or "+"
then divided by 2
If you wrote it out like this "x+5/2"it would be wrong because of PEMDAS making you want to divide first instead of after.
Point- an exact loction in space with indefinite shape and size.
line- an object with no thickness that extends infinitely in 2 directions.
line segment- a portion of a line consisting of 2 end points and all point in between.
ray- a portion of a line consisting of 1 end point and all point in between.
opposite ray- 2 ray sharing the same end point and continuing infinitely in 2 direction.
plane- a flat surface that extends infinitely in all direction.
collinear- point that lie on the same line.
non collinear- point that do not lie on the same plane.
