Answer:
The answer in the procedure
Step-by-step explanation:
Let
x-----> amount corresponding to 75%
we know that
using proportion
Answer:
720 possible ways
Step-by-step explanation:
The gold is awarded to the first position, the silver is awarded to the second position while the bronze is awarded to the third position.
The first position can be taken by any of the 10 runners
Now, the second position can be taken by remaining 9 runners
while the third position can be taken by the renaming 8 runners.
Thus, the number of ways in which these medals can be awarded = 10 * 9 * 8 = 720 ways
The expression 9c - 12- 15c - 8 - 3c is equivalent to -9c - 20.
An algebraic expression is consists of variables, numbers with various mathematical operations,
The given expression is,
9c - 12- 15c - 8 - 3c.
Solve the expression for terms c,
9c - 12 - 18c - 8
-9c - 12 -8
Further, solve for constant terms,
-9c - 20
The simplified form of the expression is -9c - 20.
