y = -4.2

If you substitute that value for <em>y</em> into the equation, you'll get 2.9 = 7.1 + (-4.2)... and that is a correct, valid equation. <em>HOPE THAT HELPS!</em>

Mark bikes 4/10 of a mile in 1/5 of an hour. Find marks average speed in miles per hour.

Triss [41]

He bikes 4/10 of a mile in 1/5 of an hour

That is 4/10 miles in 1/5 hours

Average speed = Distance/ time = 4/10 ÷ 1/5 = 4/10 × 5/1 = 2 miles/hour
