Answer:
For the choir director to collect $1,500, 165 adults need to buy tickets.
Step-by-step explanation:
Since 226 students purchased tickets, we multiply 3 times 226. Our answer is 678. Now we subtract 1,500 - 226 this equals 822. So we need to divide $822 by 5 (the price for adults). We get 164.4. For the choir director to collect $1,500, 165 adults need to buy tickets.
Answer:
The value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
Step-by-step explanation:
Given the expression
solving
We know that the equations with infinitely many solutions have the same expressions on both sides
It means the value of k can be determined by further simplifying such as
8x+20-8x = k
20 = k
Therefore, the value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
VERIFICATION:
Given
Put k = 20 in the equation
equations with infinitely many solutions have the same expressions on both sides.
This means the statement is always true.
