. Jacob and Sadie each got ahead on their skills practices. Jacob completed twelve fewer problems than twice the number Sadie completed. They completed a total of 127 problems. Which system of equations models this situation if Jacob completed j problems & Sadie completed s problems? A) j + s = 127

Answers

Answer 1

Answer:

2s-12=j

S+J=127

Step-by-step explanation:

ok so firstly you are going to have 2 problems. Jacob has 12 fewer than 2x Sadie's so it will look like this, 2s-12=j

. 2x Sadie's minus 12 will give you Jacobs. and then it tells you that together they have 127 completed so S+J=127

hope this helps!!

A car and a truck left Washington, DC traveling in opposite directions. The car
traveled 19 miles
per hour faster than the truck, and at the end of 8 hours they were
1048 miles apart. What was the average speed of each vehicle?

Answers

Answer:

The speed of the car is 75 mph.

The speed of the truck is 56 mph.

Step-by-step explanation:

Call the speed of the truck (x) miles per hour. As per the given information, the car is (19) miles per hour faster. Thus, one can form expressions to represent the speeds of the vehicles.

car = ( x + 19 ) mph

truck = ( x ) mph

Using the formula, ( (speed) * (time) = (distance) ), one can say that the speed of the car, times the time it took plus the speed of the truck times the time will equal the distance between the two vehicles:

(( car speed )( time )) + (( truck speed )( time )) = ( distance between vehicles )

Substitute,

( ( x + 19 ) ( 8 ) ) + ( ( x ) ( 8 ) ) = 1048

Simplify,

8x + 152 + 8x = 1048

16x + 152 = 1048

       -152     -152

16x = 896

/16     /16

x = 56

Add (19) to find the speed of the car:

truck speed + 19

= 56 + 19

= 75

The speed of the car is 75 mph.

The speed of the truck is 56 mph.

Answer:

The truck traveled at 81

mph. The car traveled at 100

mph.
