alexdok [17]

Answer:

B:J:S

6:8:10

6+8+10= 24 parts all together

Sarah has $50 and equals 10 parts. So, each part is worth $5. (50/10=5)

Thus, Ben receives 6 parts, with each part being $5. So, Ben gets $30. (6x5=30)

levacccp [35]

Answer:

he is currently 34

Step-by-step explanation:

x + 6 = 5(x-26)

x + 136 = 5x

-x             -x

136 = 4x

/4       /4

x = 34

You can check your work as well:

34 + 6 = 40

34 - 26 = 8

8 x 5 = 40
