Answer: =4.4n-13
Step-by-step explanation:
Let's simplify step-by-step.
2n−9−(−2.4n+4)
Distribute the Negative Sign:
=2n−9+−1(−2.4n+4)
=2n+−9+−1(−2.4n)+(−1)(4)
=2n+−9+2.4n+−4
Combine Like Terms:
=2n+−9+2.4n+−4
=(2n+2.4n)+(−9+−4)
=4.4n+−13
Question 29 is A 2 and 30 is C 3
Well, to get the x intercept you have to substitute 0 for y and solve for x, and get rid of the parenthesis ( y=2x+3*x-1*x-4 ) unless you want three different x-intercepts. So if you do want those three intercepts, leave the parenthesis.
Answer:
The zoo will cost more money for a group of 12 students to visit.
Step-by-step explanation:
First, you have to divide the costs by the amount of tickets to find out how much you would have to pay for one ticket.
Science Center: $36.76 ÷ 3 = $12.25
Zoo: $51 ÷ 4 = $12.75
Then, the cost for one ticket should be multiplied by 12, the group of students wanting to visit.
Science Center: $12.25 x 12 = $147.04
Zoo: $12.75 x 12 = $153
Comparing the prices, you will see that the zoo will cost $5.96 more dollars than the science center.
