Answer:
j = 12
Step-by-step explanation:
j + (-3) = 9
j = 12
substitute x for y-1
2(y-1)-y=6 distribute
2y-2-y=6 subtract y in 2y
y-2=6 add 2 to get y by itself
y=8
Put y back into equation x=y-1
x=8-1
X=7
Answer/Step-by-step explanation:
Given the function, 
, the table can be completed by substituting the given value of z as follows:
Question 2: z = -7
Question 3: z = -8

Answer: 10.5 cm</h3>
=======================================================
Explanation:
25% = 25/100 = 0.25
25% of 84 = 0.25*84 = 21
So 21 cm has been cut off, leaving 84-21 = 63 cm left over
Or you could say that if 25% has been cut off, then 75% of the stick remains
So, 75% of 84 = 0.75*84 = 63 cm remains.
The remaining length of 63 cm is cut into 6 equal pieces
Each smaller piece is 63/6 = 10.5 cm long
Do 12.64 divided by 4. That is each person’s cost of pizza. Then add 0.95 to the cost of pizza. That is your total.
