Mean: add A1+A2+A3+A4+……..+An then divide by 2 means 8+5+7+10+15+21=66/2=33
Answer:
x =4 ,y =4 and z =0 is the solution.
Step-by-step explanation:
We shall solve the equations using elimination method
In equation 2 and 3 we can see that coefficient of z in both equations are same with opposite sides , adding equations (2) and (3)
3y+5z = 12
y -5z = 4 adding the equations
___________
4y = 16
dividing both sides by 4
y =
y = 4
Plugging the value of y in equation 2 or equation 3 ,we get
3(4) +5z = 12
12+5z = 12
5z = 12-12 or 5z =0 gives z =0
plugging y =4 and z =0 in equation 1
2x+3(4)+ 0 = 20
2x+12 = 20
2x =20-12
2x = 8
x = 8 divided by 2 gives
x =4
therefore solution of the system is given by
x=4 , y =4 and z =0
Answer and Step-by-step explanation:
To solve, simply plug 6 in for m in the equation.
C(6) = 50(6) + 79.50
6 times 50 is 300.
300 + 79.50 = 379.50 = C(6)
The answer is 379.5
(Looking at the question again, I don't think what I said is what it is asking for, soo)
The slope of the function given represents the amount that needs to be paid every month. The y-intercept (79.50) represents the initial cost (starting amount) for paying the membership.

The number 9 in scientific notation is 8•10^0
We know that
in the figure <span>equivalent ratios are
</span>BS/BC
and
AR/AC
therefore
AR/RC is not equivalent
the answer is
AR/RC
