Mohal bought 20 chicken wings for $50.00. If Mohal spent $30.00, how many chicken wings did he buy
ELEN [110]

The number of chicken wings that Mohal can buy is 12.

<h3>How to calculate the cost?</h3>

It should be noted that Mohal bought 20 chicken wings for $50.00. The cost of each wing will be:

= Total amount / Number of chicken wings

= $50 / 20

= $2.50

When he spent $30.00, the number of wings will be:

= Amount / Cost per wing

= $30 / $2.50

= 12

There will be 12 chicken wings. This illustrates the proportion.

What is the solution to the equation x/3+x/6=7/2
nadezda [96]

Answer:

x = 7

Step-by-step explanation:

the smallest common denominator between 2 3 and 6 is 6. Multiply the original equation by 6

  • 6(x/3 + x/6 = 7/2)
  • 6(x / 3) = 2x
  • 6(x/6) = x
  • 6(7/2) = 3*7 = 21

Result

  • 2x + x = 21
  • 3x = 21
  • 3x/3 = 21/3
  • x = 7

Check

  • 7/3 + 7/6 = 7/2
  • 14/6 + 7/6 = ? 7/2
  • 21/6 =? 7/2
  • 21/6 = 3.5
  • 7/2 = 3.5

Answer: x = 7
