Answer:
Step-by-step explanation:
Jocelyn has to spend $13.46 on gas.
To find this, you first have to determine the number of miles she drives. You can find this by multiplying the speed by the travel time.
65 miles per hour * 1.5 hours = 97.5 miles.
Now that he have the amount of miles she drives, we can find the amount of gas she spends. In order to do that we'll divide the distance by the rate.
97.5 miles / 25 miles per gallon of gas = 3.9 gallons
Now we can determine the cost by multiplying the amount of gallons by the price.
3.9 gallons * $3.45 per gallon = $13.46
perimeter is 2L+2W
problem states width = 5L+13
so plug that in for w:
P=2L+2(5L+13)
now simplify
P=2L+10L+26
P=12L+26
Answer:
y = 2x
Step-by-step explanation:
There is a proportional relation between the number of pairs of socks that Jason buys,x, and the total cost (in dollars), y.
Let us assume that the relation is y = kx ..... (1)
{Where k can be assumed to be the constant of proportionality}
Now, given that Jason can buy 2 pairs of socks for $4.
So, from equation (1), we can write 4 = 2k, ⇒ k = 2
Therefore, the equation (1) becomes y = 2x. (Answer)
