Answer:
Step-by-step explanation:
We know that the sum of all the angles of a triangle add up to 180 degrees.
So, let's combine like terms:
7x + 3x + x = 11x
5 + 10 = 15
So, 11x + 15 = 180
We can rearrange the equation to look like this:
180 - 15 = 11x
180 - 15 = 165
So, 11x = 165
Then, divide:
165 / 11 = 15
So, x = 15.
Now we can find the measure of all the angles!
3x = 3 x 15 3 x 15 = 45.
7x + 5 = (7 x 15) + 5 7 x 15 = 105 105 + 5 = 110
x + 10 = 15 + 10 15 + 10 = 25
So, the angles are:
45 degrees
110 degrees
And 25 degrees

It would be a 3/4 chance that he will pull the right 4 coins.
Step-by-step explanation:
Answer:
When 2 angles are put together, they must have a total of 180 degrees.
Step-by-step explanation:
180-39=141
The measure of the missing angle is 141 degrees.
y = 70000(0.5)^(x/4), where x equals the number of hours.
(Attached is an image with the equation properly formatted.)
The function for exponential decay is <em>y = a(1 - b)^x</em>, where y is the final amount, a is the starting amount, b is the decay percentage in decimal form.
So, just fill in the values.
y = 70000(1 - 0.5)^x
y = 70000(0.5)^x
In this case however, x represents the number of sets of four hours, so we should probably divide x by 4 to make x represent the number of hours.
y = 70000(0.5)^(x-4)
The answer is (n+11)(n-4). You want to find what multiplies to make -44 and what adds to make 7.
