Answer:
0.07x - 0.002x^2 - 0.3
Step-by-step explanation:
Given the expression shown (0.2x-1)+(0.3-0.01x)
Expand
(0.2x-1)+(0.3-0.01x)
= 0.2x(0.3) - 0.2x(0.01x)-1(0.3) + 1(0.01x)
= 0.06x - 0.002x^2 - 0.3 + 0.01x
= 0.06x+0.01x - 0.002x^2 - 0.3
= 0.07x - 0.002x^2 - 0.3
This gives the required expression
Answer:
Let affan have x no. of stamps Then,
According to the question Ayaan has 20 stamps more than 3 times the number of stamps Affan has. Then,
x = 3x + 20
Now they both have 140 stamps all together. so,
x + 3x + 20 = 140
or, 4x = 140 - 20
or x = 120/4
or, x = 30
Therefore, Affan has 30 stamps .
