Combine the terms with j, so -7j+3 would be left.
X = 4
Explanation:
sqrt(x) + sqrt(5 + x) = 15 / sqrt(5 + x)
sqrt(5 + x)[sqrt(x) + sqrt(5 + x)] = 15
sqrt(5x + x^2) + 5 + x = 15
sqrt(5x + x^2) = 10 - x
Take square of both sides
5x + x^2 = (10 - x)^2
5x + x^2 = 100 - 20x + x^2
Cancel x^2
5x = 100 - 20x
25x = 100
x = 4
Answer:
of a second
Step-by-step explanation:
We can convert each time into fractions.
11.74 is the same thing as 
and 11.69 is the same thing as 
.
We know that 11 - 11 = 0, so we can focus on the fractions for now.
Let's subtract 
from 
.
.
We can now simplify 
by dividing both the numerator and denominator by 5.
.
Hope this helped!
Answer:
It is C.
First of all, we can see that angle 1 is 132 degrees because they are the same angles/measurements. Therefore, angle 1 and angle 3 are also supplementary as they create a straight line, or 180 degree angle. As they are supplementary, angle 1 + angle 3 = 180. We know that angle 1 is 132, so we have 132 + angle 3 = 180, and angle 3 is 42 degrees.
