Answer:
31 seats
Step-by-step explanation:
Let x be the smaller van, and y be the larger one.
We know that y = x + 14
We also know that 2x + y = 65
If we replace y by its value in the second equation we have:
2x + (x + 14) = 65, then we solve
2x + x + 14 = 65
3x + 14 = 65
3x = 51
x = 17
We now know the smaller van has 17 seats.
To find how many seats are in the big one, we take the first equation:
y = x + 14
y = 17 + 14
y = 31
Answer: is y=7/3x+4
Step-by-step explanation:
1) add twelve to both sides- this will cancel out the 12
2)you now have 7x+12=3y
3) divide three on both sides. note you put everything over three on the left
4) 7 over 3 (x)+4=y is what you get when you finish doing the simple computations
5) flip the whole thing around so it fits the form. remember that addition can be anywhere as long as you don't switch sides of the equation
you will get: y=7/3x+4
Answer:
8/12 or 2/3
Step-by-step explanation:
5/12+3/12=8/12
8/12 simplifies to 2/3
Answer:
7
Step-by-step explanation:
7 x 4 = 28
28 + 12 = 40
