Lets solve this system of equations using addition.
9x+2y^2-3z^2=132
+ 9y-2y^2+3z^2=867
-------------------------------
9x+9y+0y^2+0z^2=999
9x+9y=999
x+y=111
Now lets break it down into two equations
x=111-y y=111-x <-- Answer
Now we can substitute with much simpler equations to check.
x=111-(111-x)
x=111-111+x
x=x
True
y=111-(111-y)
y=111-111+y
y=y
True
Answer:
It would be c!
Step-by-step explanation:
We have been given that last month, Belinda worked 160 hours at a rate of $10.00 per hour.
Let us find amount earned by Belinda last month as:
We are also told that Belinda's employer retains 9% of her gross salary. This means that Belinda's net income will be 91% of $1600. .
Upon rounding $1456 to nearest hundred, we will get:
Therefore, $1500 is a reasonable estimate of her net salary.
