Answer: y=1
Step-by-step explanation:
First we need to get y alone.
y+3 = 4
We must subtract 3 on both sides (this will cancel out the +3 on the y side).
y=1
If you had y-3=4 then you would have to add 3 on both sides to cancel out the -3 on the y side.
If it is division you multiply and vise versa. Just do the opposite to everything on the y side to give y alone and figure out what y is equal to!
:) Best of luck!
Answer: 1.18
Step-by-step explanation:
Z = (x - mean) / standard deviation
Z = (85 - 71.4) / 11.5
Z = 13.6 / 11.5 = 1.18
0, No solution.
-4x-11=2 (x-3x)+13
-4x-11=2 (-2x)+13
-4x-11=-4x+13
-11 is not equal to 13 so there is no solution
