The bigger of two numbers is four more

Otrada [13]

Answer:

X=the smaller

y=the larger

The bigger of two numbers is four more than the smaller, then:

y=x+4

one more than twice the smaller is the same as the larger, then

1+2x=y

We have the following system of equations:

y=x+4

y=2x+1

We solve this system by equal values method:

x+4=2x+1

x-2x=1-4

-x=-3

x=3

We find the value of "y"now:

y=x+4

y=3+4

y=7

the values of x and y are:

x=3

y=7

Car 6 truck 10 suv 14 minivan 15 at this rate if 150 vehicles passed Luann how many more mini vans than cars would pass her

inessss [21]

Answer:

number of minivans more than number of car = 30

Step-by-step explanation:

we have the rate of number of vehicles passed in one unit of time

Number of cars = 6

Number of trucks = 10

Number of SUV = 14

and number of minivan = 15

Total vehicle passed in one unit of time = 6+10+14+15 = 45 vehicle per unit time.

we can see the ratio of vehicles with each other can be given as:

6x+10x+14x+15x = 150

Now we can solve for x to get the number of cars and minivans in 145 vehicles.

or 45x = 150

or x = 150÷45 = $\frac{10}{3}$

so, number of cars in 150 vehicles = 6x = 6× $\frac{10}{3}$ = 20 cars

number of minivan in 150 vehicles = 15x = 15× $\frac{10}{3}$ = 50 minivans.

So, number of minivans more than number of car = 50 - 20 = 30
