bearing in mind that standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
Answer- 31.9%
3,622,184 =100%
4,778,332= x
Criss cross
477,833,200= 3,622,184x
Divide to get x alone
X= 131.9
131.9 - 100= 31.9%
Because it asks for the change
Use one of the many Trigonometric ratios to solve for the missing angle and then use Pythagorean theorem to solve for the missing side.
These things can be done in any order.
The answer is just half of the first fraction which is 3/2
