Answer:
12^2 and 12/3
Step-by-step explanation:
Examples of inverse operations are: addition and subtraction; multiplication and division; and squares and square roots.
-1/3x-4/3y=2
1/3x-2/3y=4
First realize that the coefficient of x is -1/3 and 1/3 which can be eliminated with addition
Adding the two equations together gets
-6/3y=6
Simplify
-2y=6
y=-3
Substitute back into original equation
1/3x-2/3(-3)=4
1/3x+2=4
1/3x=2
x=6
Answer
x=6, y=-3
Check answer
-1/3(6)-4/3(-3) =?= 2
-2+4=2
2=2
Done!
Answer:
2. YWX
Step-by-step explanation:
<T and <Y are congruent
<W and <W are congruent
<Z and <X are congruent
Let x=3.77777777...
10x=37.777777777...
9x=10x-x=34
9x=34 so x=34/9=3 7/9
