The total number of hours taken by n students is modeled by
.
<u>Step-by-step explanation:</u>
Here we have , Suppose the number of hours boys B and the number of hours girls G take to complete their homework is modeled by B=2n+5 and G=3n-1, where n is the number of students. We need to write a function that models the total number T of hours it takes boys and girls to complete their homework for n students .
- The number of hours boys take to complete their homework, B=2n + 5
- The number of hours girls take to complete their homework, G = 3n – 1
We are to derive the total number T of hours taken by n students.
Total number of Hours
T=Number of hours taken by boys+Number of hours taken by Girls
T=B+G
⇒ ![T=(2n + 5) + (3n - 1)](https://tex.z-dn.net/?f=T%3D%282n%20%2B%205%29%20%2B%20%283n%20-%201%29)
Next, we simplify by collecting like terms
⇒ ![T=2n + 5 + 3n - 1](https://tex.z-dn.net/?f=T%3D2n%20%2B%205%20%2B%203n%20-%201)
⇒ ![T=2n+ 3n+ 5-1](https://tex.z-dn.net/?f=T%3D2n%2B%203n%2B%205-1)
⇒ ![T =5n+4](https://tex.z-dn.net/?f=T%20%3D5n%2B4)
The total number of hours taken by n students is modeled by

Answer:
x = 10
Step-by-step explanation:
The opposite angles in a parallelogram are congruent, then
5x - 9 = 3x + 11 ( subtract 3x from both sides )
2x - 9 = 11 ( add 9 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
