Answer:
Wilton found 10 dimes while cleaning his father's truck.
Step-by-step explanation:
Given that:
Total amount collected = $8.50 = 8.50*100 = 850 cents
Let,
x be the number of dimes
y be the number of quarters
According to given statement,
10x+25y=850 Eqn 1
y = 3x Eqn 2
Putting y=3x in Eqn 1

Dividing both sides by 85

As x represents dimes, therefore, number of dimes is 10.
Hence,
Wilton found 10 dimes while cleaning his father's truck.
Answer:

Step-by-step explanation:
Using the rule of exponents
⇔
, then
=
= 
Standard form is ax + by = c. Begin our transformation by multiplying both sides by 2 to get rid of the fraction. Notice that ax + by = c does not allow for fractions. Doing that multiplication gives us 2y=-x + 3. Now move the x over by the y by addition. x + 2y = 3. And there you go!
For

,

, all the more

, therefore no solution.
For

, we have

. Obviously that' false.
For

both

and

, where

, belong to the range

, then

belong to the range

.
Those ranges don't have a common part, therefore, again, no solution.
So, the equation

doesn't have a solution.
Hey!
so for the first one its 60°, and for the second one its 1/6
