Matt paid $18.64 for 4 pounds of cashews. How much would he pay if he purchased 6 pounds of cashews?
Tanya [424]

Answer:

The correct answer is $27,96.

Step-by-step explanation:

First we must analyze the information we have:

We know that Matt paid $ 18.64 for 4 pounds of cashews.

Now what we want to know is how much I would pay if he bought 6 pounds of cashews.

Having 3 of 4 incognitas the most convenient thing is to do a cross-multiplication:

If he paid 18.64 ----- for 4 pounds

          He paid x ------ for 6 pounds.

x. 4 = 18.64. 6

Now we just solve the equation:

x.4 = 111.84

x = 111.84: 4

x = 27.96

In this way we show that Matt would pay $ 27.96 for 6 pounds of cashews.

Dafna11 [192]

Answer:

The actual number of passengers on the bus falling by 8 after the second stop

Step-by-step explanation:

Assume that the total passengers on the bus before 2:30 was x

At 2:30:

11 passengers got off and 8 got on.

So, the number of passengers

= x - 11 + 8

= x - 3

10 minutes later:

5 passengers got off the bus

So, the number of passengers

number of passengers = (x - 3) - 5

number of passengers = x - 8

now by comparing,

The actual number of passengers on the bus falling by 8 after the second stop
