So first, I would assign the small van a variable for how many people it can hold, or x.
So since it makes two trips,
2x
And since the other van can hold six more people,
2x + x + 6
And 57 people are transported:
3x + 6 = 57
We can then solve.
3x = 57 - 6
3x = 51
x = 17
So since we now know a small can hold 17 people, and we know that the larger van has 6 more seats, we can just say
17 + 6 = 23
So the large van has 23 seats.
That is called a constant
like 2,3,234234, -903
it doesn't have a placeholder
Answer:
B
Step-by-step explanation:
10 weeks is the number of weeks they have been saving their money.
Duane = $5 every two weeks
Mick = $2 every week.
Get the value of Duane's weekly contribution = $5 / 2 = $2.5
Duane's share + Mick's share = $45
$2.5x + $2.0x = $45 ===>> equation can also be x(2.5 + 2) = 45
$4.5x = $45
$4.5x / $4.5 = $45 / $4.5
x = 10 weeks.
To check:
$2.5(10) + $2(10) = $45
$25 + $20 = $45
