Answer:
Step-by-step explanation:
← Equation 1
By simplifying the above equation we get,
(Simplifying the brackets)
(By subtracting 
from 
) ← Equation 2
Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.
Equation 1 multiplied by 5 will give,
Equation 2 multiplied by 3 will give,
Add those together,
(After simplifying 
values)
Therefor
By substituting to Equation 1 we get,
Therefor we can say,
Area of a circle: pi r^2
R: radius = half of diameter
Pi: 3.14
^2: squared
3.14^2 * 13 = 530.93
Answer:
<h2>y=-6/5x</h2>
Step-by-step explanation:
Answer:
Josh makes $36 more per hour than Greg.
Step-by-step explanation:
First, you need to determine the amount Josh earns per hour as you know that it takes him 5 hours of work to save $480:
5x=480
Now, you can solve for x:
x=480/5
x=96
Then, you need to determine the amount Greg earns per hour as you know that it takes him 8 hours of work to save $480:
8y=480
Now, you can solve for y:
y=480/8
y=60
96-60=36
According to this, the answer is that Josh makes $36 more per hour than Greg.
The answer to this question is sqrt(2)/2. Invoke the unit circle to derive this expression, or use special triangles and reference triangles.
