Solve. 6y=192<br> a. -32<br> b. -18<br> c. 18<br> d. 32

fredd [130]

(the opposite of the multiplication of 6 is to divide each side by 6)

6y = 192

6y ÷ 6 = 192 ÷ 6

y = 192 ÷ 6

y = 32

The answer is D. 32

A girl is pedaling her bicycle at a velocity of 2.35 km/min. How far will she travel in 2 hours?

Natali5045456 [20]

Answer:

282 km

Step-by-step explanation:

Use formula

$D=v\cdot t,$

where

d - distance

v - velocity

t - time

In your case, t = 2 hours. Note that 1 hour = 60 minutes, so 2 hours = 120 minutes.

v = 2.35 km/min

Hence,

$D=2.35\cdot 120=282\ km$
