Answer:
(-1,1)
Step-by-step explanation:
5x+2y= -2, x= -1/3 - 2/3y
5( -1/3 - 2/3y) +3y= -2
y= 1
x= -1/3 - 2/3 × 1
x= -1
Answer:

Step-by-step explanation:
Average length 
Standard deviation 
Sample size 
Generally The point estimate for the mean length of all bolts in inventory is


4 friends evenly dividing up a n - slice pizza
So each one get
slices of pizza.
For example, if n = 12 slice then each friend gets 12/4 = 3 pieces. If Harris ate one slice less then he ate
=3 -1 = 2 pieces.
So the general expression for slices of pizza did Harris eat is

X+y=11
22x+15y=228
y=11-x
22x+15y=228
22x+15(11-x)=228
22x+165-15x=228
7x+165=228
7x=63
x=9
9+y=11
y=2
The solution to the system of equations is (9,2)
