Answer:
The fraction will increase by 100%
Step-by-step explanation:
Say the fraction is x/y. The question is telling us to decrease x by 20% (i.e. 0.8x) and to decrease y by 60% (i.e. 0.4y):

You can see that by applying these changes, the new fraction is actually double the old fraction (i.e. will increase by 100%).

I'm sorry that I don't speak in Filipino but I can help fill in the blanks.
(In brackets is the English translation)
12 pulgada = 1 piye (12 inch is 1 foot)
1 yard = 3 piye (1 yard is 3 feet)
10 sentimetro = 1 desimetro (10 centimeters is 1 decimeter)
1000 metro = 1 kilometro (1000 meters is 1 kilometer)
10 millimetro = 1 sentimetro (10 millimeters is 1 centimeter)
I believe the answer is 4/5x +2. Sorry if I’m wrong.
Answer:
Step-by-step explanation:
(x+3)² -5 =0 , use the formula (a+b) ² = a²+b²+2ab
x²+9 +6x -5 =0 , combine like terms
x²+6x +4 =0, use the quadratic formula x = (-b±√b²-4ac)/2a
x= (-6 ±√6²-4*1*4)/2*1
x= (-6 ± √36-16) /2
x= (-6±√20)/2
x=(-6 +2√5)/2 and x=( -6-2√5) /2, factor 2 in the numerator and simplify
x= -3 +√5 and x= -3 -√5
