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)
Answer:
x = 4/5
Step-by-step explanation:
1) Group like terms
4x + 7x + 5x - 2 - 10 = x
2) Add similar elements
16x - 2 - 10 = x
3) Subtract
16x - 12 = x
4) Add 12 to both sides
16x - 12 + 12 = x + 12
5) Simplify
16x = x + 12
6) Subtract x from both sides
16x - x = x + 12 - x
7) Simplify
15x = 12
8) Divide both sides by 15
15x/15 = 12/15
9) Simplify
x = 4/5

Answer:
639 students attend the highschool
Step-by-step explanation:
<em>Find one-ninth of the students</em>
<em>Since 142 students is two-ninths of students, we would divide</em>
1) 142/2=71
<em>71 students is only one ninth of the students, we need to find 9/9 of students</em>
2) 71*9 = 639
639 students attend school
