Answer:

11 4-passenger cars

Step-by-step explanation:

let 'x' represent the number of 4-passenger cars,then 'x-3' represent the number of 6-passenger cars.

92=4x+6(x-3)

92=4x+6x-18

92=10x-18

92+18=10x

110=10x

x=110/10

x=11

Therefore there are 11 4-passenger cars

I'm not understanding this very well can anyone help me?
vladimir2022 [97]

Answer:

x = 25

Step-by-step explanation:

Noting that these figures are similar, we set up and solve an equation of ratios:

x       30

---- = ------

15       18

Cross multiplying, we get:

18x = 30(15), or 3x = 5(15) = 75.  Then x must be 25.

If 1/2 is subtracted from four times the reciprocal of a number, the result is 0. Find the number.
Maurinko [17]

Answer:

The Number is 8.

Step-by-step explanation:

Let the number be x.

Given:

1/2 is subtracted from four times the reciprocal of a number, the result is 0.

Hence the equation will become like;

4\times \frac{1}{x} - \frac{1}{2}=0

Now Solving the equation we get.

\frac{4}{x} -\frac{1}{2}=0\\\\\frac{4}{x} = \frac{1}{2}\\\\x= 4\times 2\\x=8

Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.

Hence the number is 8.
