Joyti cut a 21 m long rope into pieces of 7/2 m length each. How many pieces of the rope did she get?

It is given that Sunita cuts a 21-metre long rope into 7/2 metre long pieces .

Total length of rope = 21 m

Total length of rope = 21 m Number of cut - pieces = 7/2 m

Let Required Number of pieces be x

Step-by-step explanation:

☞ 21 = x × 7/2

☞ 21 × 2 = 7x

☞ 42 = 7x

☞ x = 42/7

☞ x = 6

Therefore, Required Number of pieces of rope are 6.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
