Answer:

x = 9

Step-by-step explanation:

The big triangle is similar to smaller one so we can use the side lengths' proportion to find x:

7/4 = (x-3)+8/8

7/4 = (x+5)/8 cross multiply expressions

56 = 4x + 20 subtract 20 from both sides

36 = 4x divide both sides by 4

9 = x

scholars want to share 9 chocolate bars so that each scholar gets the same amount. How much chocolate bar will each scholar get?

bazaltina [42]

I'm not exactly sure how to answer this question without knowing the number of scholars. However, if you do know the number of scholars, you can divide that number by 9. The quotient will give you the amount of chocolate each scholar can receive.
