Why is 16:14 and 64:60 not equivalent
Answers
Answer 1
Answer:
The 2 ratios are almost equivalent, but not quite. In order to tell if they are equivalent, there are a number of ways but the 2 most common are 1, finding the decimal equivalent of the fraction, and 2, finding the scale factor.
1: Take 16, divide by 14. You should get something around 1.142. Take 64, divide by 60. You should get something around 1.066666.... Not equivalent.
2: Find the scale factor between the 2. To find scale factor, divide the larger numerator and larger denominator by the smaller numerator and smaller numerator. 64/16, 60/14. Not equal.

Answer 2
Answer:
16:14 =16/14
64:60=64/60
16/14=64/60
(We r doing the cross thing)
16x60=14x64
960=896
Is 960 equivalent (equal) to 869 ? No .
So they r not equivalent because the result is not the same.
64:60=64/60
16/14=64/60

x-y is half of x+y
Write x in terms of y
Answers
You said that (x - y) is half of (x+ y) . I can work with that.
(x - y) = 1/2 (x + y)
x - y = 1/2 x + 1/2 y
Multiply each side by 2 :
2x - 2y = x + y
Subtract 'x' from each side:
x - 2y = y
Add 2y to each side:
x = 3y
They can be ANY two numbers, as long as 'x' is triple whatever 'y' is.
Let's try a couple:
x = 18, y = 6
(x - y) = 12
(x + y) = 24
12 = 1/2 of 24x
yay !
x = 30, y = 10
(x - y) = 20
(x + y) = 40
20 = 1/2 of 40
yay !
x = 3π, y = π
(x - y) = 2π
(x + y) = 4π
2π = 1/2 of 4π

X-y =x+y all over 2
Add the y onto the other side making x = x+y all over 2 +y
Then you times everything by 2
2x = x+2y
Subtract x from both sides giving you
X=2y
Add the y onto the other side making x = x+y all over 2 +y
Then you times everything by 2
2x = x+2y
Subtract x from both sides giving you
X=2y

Well use the trig function sin to help.
sin(x) = 6/10 = .6
Then use inverse sign to figure out x.
x = sin^-1(.6) = 36.87 degrees.
Because angle B is not actually 90 those 5 degrees will make angle C larger than 36.87 degrees.

For a problem like this, it is best to convert all numbers to a similar form making them easier to compare. I am going to convert them all to decimals, although converting them all to fractions can also work.
-0.4 is already a decimal, so it needs no conversion; the same goes for 0.48.
4/8 is equal to 1/2, which equals 0.5 as a decimal. -4/8 is the same as -1/2, which is -0.5.
Therefore, we are left with the following converted numbers:
-0.4; 0.48; 0.5; -0.5
Now to simply order them from least to greatest, we will start with the two negative numbers because they are both below zero. When comparing negative numbers, the "bigger" one is actually smaller because it is farther below zero. Therefore, -0.5 is the smallest, followed by -0.4.
Now for the last two, 0.5, or 0.50, is 0.02 bigger than 0.48. Therefore, 0.48 is the second largest number and 0.5 is the largest.
This is the order now:
-0.5 (smallest)
-0.4 (2nd smallest)
0.48 (2nd largest)
0.5 (largest)
Now they simply need to be converted back to their original form (if applicable):
-0.5 = -4/8
-0.4 = -0.4
0.48 = 0.48
0.5 = 4/8
This leaves us with the answer:
-4/8; -0.4; 0.48; 4/8
-0.4 is already a decimal, so it needs no conversion; the same goes for 0.48.
4/8 is equal to 1/2, which equals 0.5 as a decimal. -4/8 is the same as -1/2, which is -0.5.
Therefore, we are left with the following converted numbers:
-0.4; 0.48; 0.5; -0.5
Now to simply order them from least to greatest, we will start with the two negative numbers because they are both below zero. When comparing negative numbers, the "bigger" one is actually smaller because it is farther below zero. Therefore, -0.5 is the smallest, followed by -0.4.
Now for the last two, 0.5, or 0.50, is 0.02 bigger than 0.48. Therefore, 0.48 is the second largest number and 0.5 is the largest.
This is the order now:
-0.5 (smallest)
-0.4 (2nd smallest)
0.48 (2nd largest)
0.5 (largest)
Now they simply need to be converted back to their original form (if applicable):
-0.5 = -4/8
-0.4 = -0.4
0.48 = 0.48
0.5 = 4/8
This leaves us with the answer:
-4/8; -0.4; 0.48; 4/8
