1 answer:

5 0

You will need to subtract 3x from 5x, then since there is a minus sign in front of the 7 it will count as a -7, so u add 7 cross it out and then add 7 to the -4(which is also negative cause it has a minus sign in front) and then you have ur answer

5x-3x=2x
7+ -4= 3

213

Step-by-step explanation:

The circumference of the wheel is given by

C=2πr=πd

Where d is diameter, r is radius and c is circumference

The number of revolutions N multiplied by circumference should yield the total distance

N*πd= Distance

Given distance of 20, 000 cm and diameter of 30 cm

30πN=20000

Making N the subject of formula

N=20000/(30π)=212.20659078919378102517835116335248271261

Rounded off, about 213 revolutions are required
