Yes, 18 x 2 + 36, therefore the student was correct
Step-by-step explanation:
the answer is in the image above
The third term is 9
t(3)=2(3)+3
6+3 = 9
13x-9=16
+9 +9
13x= 25
---- -----
13x 13x
x=1.92
Add nine to both sides of equation to cancel out the negative nine. Then, divide both sides by 13, which will result in the answer listed above.
For this case, the first thing we must do is define variables.
We have then:
x = Carli's bill
y = Angela's bill
We have then:
"their total bill was $ 109"
x + y = 109
"Carli went over her data limit on her phone, so her share of the bill was $ 15 more than Angela's"
x = y + 15
Answer:
A system of equations that represents this situation is:
x + y = 109
x = y + 15
