Answer:
Step-by-step explanation:
•Solve equation 1 for the variable x.
x = 3y - 27
•Plug this in for variable x in equation 2.
2×(3y-27) - 2y = 18
4y = 36
•Solve equation 2 for the variable y.
4y = 36
y = 9
•By now we know this much:
x = 3y-27
y = 9
•Use the y value to solve for x.
x = 3(9)-27 = 0
•Solution: {x,y} = {0,9}
Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.49
Answer: 720
Step-by-step explanation: to solve this problem, we do 15*8*12= 1440
this shape is half of that though, so we do 1440/2= 720, so the answer is 720
I beleive that x would equal 50
A decimal equivalent to another decimal is the same number but with more zeros on the right hand side.
0.68 = 0.680 = 0.6800 = 0.68000 etc.
0.9 = 0.90 = 0.900 = 0.9000 = 0.90000 etc.
Just pick whichever two numbers you like :)
