Im willing to give 20 points maybe even more
Thepotemich [5.8K]

Answer:

Equations are

20c + 10m = 495..............(1)

8c + 1m = 178.5.................(2)

Now ,  equation (2) * 10 = 80c + 10m = 1785...........(3)

So, Eq. (3) -  Eq(1) =

80c + 10m - 20c - 10m = 1785 - 495

60c = 1290

c= 21.5

********************************************************

Now place the value of c in Eq (2)

So , m =6.5

The sum of three numbers is 3068.Two of the numbers are 1266 and 1755,find the third number<br><br>​
ratelena [41]

Answer:

The third number is 47.

Step-by-step explanation:

The sum of three numbers is 3068 - this can be expressed mathematically as:

\displaystyle{x + y + z = 3068}

Given that two of the numbers are 1266 and 1755 (in order) then substitute x = 1266 and y = 1755:

\displaystyle{1266 + 1755 + z = 3068}

Find the third number - solve for z-variable:

\displaystyle{3021 + z = 3068}\\\\\displaystyle{z = 3068-3021}\\\\\displaystyle{z = 47}

Therefore, the third number is 47.
