5:6
The fraction 85/102 goes to 5/6 so it is 5:6 or 5/6...
We want to solve
4/7 = x/161
Cross multiply.
7x =(4)(161) = 644
Divide each side by 7.
x = 644/7 = 92
Answer: x = 92
We need to multiply the factors (x - 2) and (x^2 + 9x + 10) to see if the product is the original expression given.
(x - 2)(x^2 + 9x + 10)
x^3 + 9x^2 + 10x - 2x^2 - 18x - 20
x^3 + 7x^2 - 8x - 20.
Since the product just found is not the original expression given, Jimmy is wrong.
I will complete the work on paper by synthetic division and post my answer.
After using synthetic division, the correct quotient is x^2 + 9x + 20.
Answer:
1:500
Step-by-step explanation:
Since it has already given you the conversion factor, the ratio is 1:500, where every 1 cm is 500 km.
