------------------------------------------------------------
Define the two numbers
------------------------------------------------------------
Let one number be x and the other be y

------------------------------------------------------------
Form equations and solve
------------------------------------------------------------
x + y = -14 --------------- (1)
y - x = 12 ------------------(2)

------------------------------------------------------------
(1) + (2)
------------------------------------------------------------
2y = -2
y = -1

------------------------------------------------------------
Substitute y = -1 into (2)
------------------------------------------------------------
y - x = 12
-1 - x = 12
x = -1 -12
x = -13

------------------------------------------------------------
Answer: x = -13, y = -1
------------------------------------------------------------

The answer is 25%.

First: work out the difference between the two numbers you are comparing.  

Decrease = Original Number - New Number

35-28=7


Then: divide the decrease by the original number and multiply the answer by 100.  % Decrease = Decrease ÷ Original Number × 100


7÷

28=.25

.25*100=25

Solve five and three sixths minus two and one third.
CaHeK987 [17]

Answer:

3 3/18

Step-by-step explanation:

5 3/6-2 1/3

We first need to turn our mixed numbers into fractions by multiplying the while number by the denominator, then adding the numerator. When we do this, 5 3/6 turns into 33/6 and 2 1/3 turns into 7/3. Now we have this:

33/6-7/3

Now we need to find the Least common multiple of the denominators in order to find our common denominator, which in this case is 6. 33/6 already has a denominator of 6, so we do not need to do anything to it. To give a denominator of 6 to 7/3, however, we must multiply by 2, giving us this:

33/6-14/6

Now we can subtract the numerators.

19/6

To turn this back into a mixed number, we divide 19 by 6, which gives us 3 with a remainder of 1. Therefore, our answer is 3 1/6. This is an equivalent fraction to the fourth answer, 3 3/18.

AnnZ [28]

Based on the information given, the speed is 20 miles per hour.

From the information given, the winner of the local triathlon swam 0.5 miles, biked 15 miles and ran 2.5 miles and he finished the race in 54 minutes.

Note that 54 minutes = 0.9 hour.

The speed will be:

= (0.5 + 15 + 2.5) / 0.9

= 18/0.9

= 20 miles per hour.
