Evaluate j2 − 3k + j, when j = 6 and k = 10.
To evaluate the expression j^2 - 3k + j when j = 6 and k = 10, substitute the values of j and k into the expression:
(6)^2 - 3(10) + 6
Simplify the expression:
36 - 30 + 6
Combine like terms:
6
Therefore, when j = 6 and k = 10, the expression j^2 - 3k + j evaluates to 6.
wrong
Apologies for the mistake.
Let's evaluate the expression j^2 - 3k + j when j = 6 and k = 10.
First, substitute the values of j and k into the expression:
(6)^2 - 3(10) + 6
Simplify:
36 - 30 + 6
Combine like terms:
6 + 6
Final result:
12
Therefore, when j = 6 and k = 10, the expression j^2 - 3k + j evaluates to 12.
that was right good job
Thank you for confirming! I'm glad the answer is correct. If you have any more questions, feel free to ask.
The cost to see a movie is $10 for adults and $6 for children. The total cost is 10x+6y
where x
is the number of adults and y
is the number of children seeing a movie. What is the total cost if 3 adults and 5 children see a movie together? (1 point)
The total cost is $
.
To find the total cost when 3 adults and 5 children see a movie together, we can substitute the values of x (number of adults) and y (number of children) into the expression 10x + 6y.
Given x = 3 (number of adults) and y = 5 (number of children), substitute these values into the expression:
10(3) + 6(5)
Simplify the expression:
30 + 30
Combine like terms:
60
Therefore, if 3 adults and 5 children see a movie together, the total cost would be $60.
right!
Thank you! I'm glad the answer is correct. If you have any more questions, feel free to ask!
