Can you Find the solution of the system of equations?

Lunna [17]

Answer:

x = 3

y = 2

Step-by-step explanation:

multiply by -1 the second equation and add the two equations

$7x-7y=7\\4x+7y=26$

$11x=33$

$x=33/11$

$x=3$

"y" is calculated:

$7(3)-7y=7$

$21-7y=7$

$-7y=-14$

$y=\frac{-14}{-7} =2$

Hope this helps

Rico bicycles at an average speed of 15.5 miles per hour. What distance will Rico bicycle in 180 minutes?

Tpy6a [65]

Answer:

46.5 miles

Step-by-step explanation:

Average speed × Time in hours = Distance

Average speed = 15.5 Miles per hour

Time = 180 minutes

We convert to hours

60 minutes = 1 hour

180 minutes = x

Cross Multiply

60x = 180

x = 180/60

x = 3 hours

Distance = 15.5 miles per hour × 3 hours

Distance = 46.5 miles

The distance Rico will ride his bicycle is 46.5 miles
