Answer:
You = bronze
Your brother = silver
Your sister = gold
Step-by-step explanation:
Your marks: 40/60
Your brother's marks: 46/60
Your sister's marks: 49/60
You can simplify the fractions, but you don't have to:
40/60 = 2/3
46/60 = 23/30
49/60 = 49/60
Now, divide each of the numerators by the denominators (turn the fraction into a decimal).
2/3 = 0.6667
23/30 = 0.7666667
49/60 = 0.8166667
(Note that these are all approximations as the real answers go on forever)
Lastly, multiply them all by 100 to get the percent.
0.6667 x 100 = 66.67% - bronze
0.76667 x 100 = 76.667% - silver
0.816667 x 100 = 81.6667% - gold

Answer:
2x² - 5x - 3
Step-by-step explanation:
Given
(x - 3)(2x + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(2x + 1) - 3(2x + 1) ← distribute parenthesis
= 2x² + x - 6x - 3 ← collect like terms
= 2x² - 5x - 3
Answer:the cost of each CD for a member is $5.25
Step-by-step explanation:
The membership costs $22 per year, and then a member can buy CDs at a reduced price.
Let x represent the cost of each CD for a member.
Let n represent the number of CDs that each member buys. This means that the total cost of buying n CDs for a member for a year would be
22 + nx
If a member buys 17 CDs in one year, the cost is $111.25. This means that
17x + 22 = 111.25
17x = 111.25 - 22 = 89.25
x = 89.25/175 = 5.25
