Answer:
y = 7
Step-by-step explanation:
The diagonals of a rectangle are congruent and bisect each other, then
AC = BD , that is
AE + EC = BD [ AE = EC = 6y ]
6y + 6y = 84
12y = 84 ( divide both sides by 12 )
y = 7
Answer: y= -1/2x + 5/2
Step-by-step explanation:
3x = 15 -6y
+6y + 6y
3x +6y =15
-3x -3x
6y= 15-3x divide both sides by 6
y= 15/6 - 3/6x
in slope intercept form us y= -3/6x + 15/6 in simplest form is y= -1/2x + 5/2
Answer:
90.
Step-by-step explanation:
We have two lines of code:
y ← x + x + x + x + x
z ← y + y + y
and, x=6 before the execution. Then, when the program starts to run we obtain:
y ← 6 + 6 + 6 + 6 + 6
y ← 30
z ← 30+30+30
z ← 90.
Then, the value of z after excecution is 90.
The mean is 10 because you will add all the numbers and then divide the answer by 4
