The answer if 7 years, if you multiply 2,000 by .02 it equals 40. so you divide 280 by 40 and get 7
Step-by-step explanation:
yes yours answer is correct .
Could be y=8x + 16?
The gradient is 8 bcause each time x increases by one y increases by 8
Answer:

Step-by-step explanation:
We have the different denominators.
The common denominator is 10.

We can subtract these fractions now.

40 cm.
let the length of the first part be 3x, second part be 4x, third part be 5x.
where x is a positive length in cm.
why 3x,4x and 5x ?
so that the ratio of lengths of the 3 parts be 3:4:5.
total length of the stick = 3x + 4x + 5x = 12x=96cm
so x=96/12 = 8cm
therefore the largest part of the stick (5x)= 5*8 =40cm
