Answer:
9
Step-by-step explanation:
3x-16=2x-7. Add 16 to both sides to get 3x=2x+9. Then subtract 2x on both sides to get x=9
Answer:
Let's denote:
The cost of buying 1 burger: x
The cost of buying 1 drink: y
Then, we have:
5x + 3y = 13 (1)
3x + 5y = 11 (2)
Add up both sides of (1) and (2):
=> 8x + 8y = 24
=> x + y =3 (*)
Subtract both sides of (1) to (2):
2x - 2y = 2
=> x - y = 1 (**)
From (*) and (**):
x = 2
y = 1
=> The cost of buying 2 burgers and 2 drinks: 2(x + y) = 2(2 + 1) = 6$
The answer would be 1.
This is due to 5+8 equaling 13.
Then if you subtract 1 from 14 you also get 13.
Answer:
Now, each student contributes= Rs 61 1/2= Rs 123/2 ( mixed fraction ).
Therefore, total no. of students=Rs (1953/2÷123/2) = 15.87
Rounding off 15.87 to 16.
There were 16 students
(i hope it is correct answer. pls mark as brainliest)
4 twos = 4x2 = 8 8-5=3 p=3
