At discount copy,12 copies cost $0.66. Melissa needs 56 copies . How much should they cost ? ....show work
Answers
Then
Cost of 1 copy that Melissa needs to pay = (66/12) dollars
= 11/2 dollars
Now
The cost of 56 copies that Melissa has to pay =(11/2) * 56
= 11 * 28 dollars
= 308 dollars
So Melissa needs to pay $308 for 56 copies.I hope the procedure is clear enough for you tounderstand. In future you can use this procedure to solve similar problems in future.
(Note that the unit cancels out so you get the answer)
The final answer is $3.08~

so 2.6 in meters is 2600 so
2600+475= 3075
its 3075 meters divide by 1000 to equal
3.075 kilometers
hope it helps
East side = 2.6 km + 475 m
475 m = 475/1000 m = 0.475 km
East side = 2.6 km + 0.475 km
East side = 3.075 km.

What is linear equation ?
"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C"
Given,
Stacy has s stamps.
Then, from the question it is clear that Dominic has 3s-6 stamps
So, the number of stamps that Mary received will be 3s-6 +s = 4s-6
Hence, option C is the correct option.
To know more about linear equation here
#SPJ2
Since Stacy has 3 times more stamps than Dominic does, you write 3s - 6
If you multiply 6 x 3 you get 18, giving you 3s - 18
B= 2
C= 3
D= 4

Answer:
`Option B.
Step-by-step explanation:
The given system of equations is
The graph of first equation is circle and the graph of second equation is a line.
We know that a line can intersect a circle at most 2 times. So, the greatest possible number of solutions is 2.
First equation can be rewritten as
It is the standard form of a circle , where (h,k) is center and r is radius.
In the above equation h=0,k=0 and r=3. It is a circle with radius 3 and centered at origin.
The second equation is
It is a linear equation.

Plot these points on a coordinate plane and connect them by a straight line.
From the below graph it is clear that the line and circle intersect each other at two points. So, the given system of equation have two solutions.
Therefore, the correct option is B.
