Two cyclists, 40 miles apart, start riding toward each other at the same time. One cycles 3 times as fast
Dmitry [639]

Answer:

  15 mph

Step-by-step explanation:

The cyclists will cover distance at a rate proportional to their speed. So, the distance ratio is ...

  faster cyclist distance : slower cyclist distance = 3 : 1

Then the faster cyclist covers 3 : (3+1) = 3/4 of the total distance, or (3/4)(40 mi) = 30 mi.

That distance took 2 hours for the faster cyclist, so the speed was ...

  speed = distance/time = 30 mi/(2 h) = 15 mi/h

A-lines slope is 7 and its y-intercept is 10 what is the equation of the slope-intercept form?
Trava [24]

Answer: y = 7x + 10

Step-by-step explanation:

Slope-intercept form is: y = mx + b

where m is the slope and b is the y-intercept.

Knowing this, you can plug in your values for the slope and the y-intercept in place of their respective variables. The slope of 7 would replace m and the y-intercept of 10 would replace b to get y = 7x + 10.

mihalych1998 [28]

Answer:

y = 10  PLEASE GIVE BRAINLIEST

Step-by-step explanation:

The angles of this triangle should all add up to 180 degrees.

There are 3 angles so 180 ÷ 3 = 60.  Each angle will = 60 degrees.

To find y:

5y + 10 = 60

5y = 60 - 10

5y = 50

y = 50 ÷ 5

y = 10
