Answer:

13%

Step-by-step explanation:

There are three groups: bikes, buses, and cars.  The percentages of each must add up to 100%.

bikes + buses + cars = 100%

bikes + 17% + 70% = 100%

bikes + 87% = 100%

bikes = 13%

Solve s=m/4(a+h) for h
Pavlova-9 [17]

Answer:

h = (m/4 - as)/s

Step-by-step explanation:

s = m / 4(a+h)

(a+h) · s = m/4  ><em>multiplied </em><em>(a+h)</em><em> on both side</em>

as + hs = m/4  ><em>distributed the </em><em>s</em><em> to </em><em>(a+h)</em>

hs = m/4 - as  ><em>subtracted </em><em>as</em><em> on both side</em>

h = (m/4 - as)/s<em>  >divided </em><em>s</em><em> on both side</em>
