4. A plant grows during the first month after it is planted. During the second month it grows by half the height it had already reached. During the third month it grows by one third of the
height it had re shed at the end of the second month. It then grows by one quarter and one
fifth of the height reached in the same way in the next two months.
(a) If a plant is 1 metre tall at the end of the first month,
how tall will it be after five months?

m
(b) If a plant grows 90 cm in the third month,
how tall was it after one month?

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

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

0.50 , 0.75
