6C + 47M=893.50<br> 25C + 22M=527.86
Olenka [21]

Answer:

C = 4.94   M = 18.38

Step-by-step explanation:

the easiest way is to graph both equaitons and see where they intersect,

see the image

or solve by substitution

6C + 47M=893.50           C = (893.50 - 47M)/6

25C + 22M=527.86

25((893.50 - 47M)/6)  + 22M = 527.86

25/6 [(893.50) - 47M] + 22M = 527.86

25/6 [ - 47M] + 22M = 527.86 - 25/6 [(893.50)

22M - 25(47M)/6  = -3195.06

22M - 195.83M  = -3195.06

      -173.83M   =   -3195.06

                 M  =  18.38

C = (893.50 - 47(18.38)/6

C = 4.94

Yuri is shopping for new workout clothes. He picks up a shirt for $12.50 and two pairs of shorts for $14.75 each. His total, wit
Annette [7]

The equation that can be used to determine the tax rate, x is ;44.31 = 42 + (x% of 42) where x = 5.5%

<h3>How to write equation</h3>

  • Cost of a shirt = $12.50
  • Cost of each shorts = $14.75

  • Cost of two shorts = 2 × $14.75

= $29.5

  • Total cost = $12.50 + $29.5

= $42

  • Tax rate = x%

  • Total amount paid = $44.31

Total = total cost + x% of total cost

44.31 = 42 + (x% of 42)

44.31 = 42 + 42x/100

44.31 - 42 = 42x/100

2.31 = 42x / 100

x = 2.31 ÷ 42/100

= 2.31 × 100 /42

= 231/42

= 5.5%

6 1/2 + 1 3/5 + 4 3/4​
taurus [48]

Answer:

The answer for this question would be 85 and 17/20 or /20

Step-by-step explanation:

You must first find the LCD of these terms (everything that is separated by the addition signs).

The LCD is 20 because:

2 x 10 = 20

5 x 4 = 20

4 x 5=20

and there is no number lower than 20 that all of these numbers share in their multiplication table.

Now you must multiply every term by the number you used to make its denominator 20. Since 2 x 10 = 20, the new term would be:

60 10/20

Since 5 x 4 = 20, the new term would be:

4 12/20

Since 4 x 5 = 20, the new term would be:

20 15/20

Now we put all the whole numbers and numerators together to get:

60 + 4 + 20 = 84             -        whole numbers

10 + 12 + 15 = 37             -       numerators

84   37/20  =    85  17/20 or 1717/20
