Two vehicles start from the same point traveling in the same direction. One vehicle travels 55 miles per hour (mph) and the other 45 mph. When will the two vehicles be 350 miles apart?

Answers

Answer:

45 x + 55 x = 350

x increases until the total equals 350

45 + 55 = 100 = relative speed of approach

(B) traveling cars meet this equation's specifications (x = 3.5)

The correct statement is option B)

What is the speed of an object?

Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time

Given here: The equation as 45x+55x=350

A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road.

Therefore the relative speed of the two trucks is given by 45+55=100

and let the time taken to meet is x then we can construct an equation as follows x=350/100

or,  45x+55x=350

Hence, The correct statement is option B)

What is Number?

A Number is an arithmetic value used for representing the quantity and used in making calculations.

Given that the product of a number and 3 is equal to the 14 less than product of twelve and that number.

Let the number be x

3x + 4 = 12x - 14

12x - 3x = 14 + 4

9x = 18

x = 2

Hence, the required number is 2.

Please help me solve this: y=8x 4x+y=48

Answers

Answer: x=4, y=32

Step-by-step explanation:

y=8x

4x+y=48

Plug in 8x for y in the equation

4x+8x = 48

Add like terms

12x= 48

Divide both side by 12

12x/12=48/12

x= 4

Then plug 4 back into the original equation in place of x

4(4)+y=48

16+y=48

Minus 16 from both sides

y= 48-16

y= 32

Answer: (4,32)

Answer: x = 4

Step-by-step explanation: 48 divided by 12 = 4

4 x 4 = 16

Y = 8x

8 x 4 = 32

32 + 16 = 48
