Step-by-step explanation:

Circumference of wheel = πd = 0.75πm.

How far the car travels per minute

= 60s * (14m/s) = 840m.

Hence number of revolutions per minute

= 840m / 0.75πm

= 356.507....

= 357. (nearest whole number)

Hey there!

4.50x + 5.50x - 7.50x

= 4.5x + 5.5x - 7.5x

COMBINE the LIKE TERMS

= (10x - 7.5x)

= 10x - 7.5x

= 2.5x

≈ 2.50x

Whats the answer to 3,000(6-2) + 3,000

yuradex [85]

The answer is 15000

$3000 \times ( 6 - 2) = 12000 + 3000 = 15000$
3000*6=1800
3000*-2=-6000
18000-6000=12000
12000+3000=15000
