Answer:
716.31454 and 228.01π
Step-by-step explanation:
Area = πr^2
π · 15.1^2 ≈ 716.31454
Area in terms of pi = 228.01π

Answer:
Step-by-step explanation:
We have been given the equation:
And 
Second equation can be rewritten as:
We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:
Now substitute in equation (1) we get:
Step-by-step explanation:
Hi there,
The sum of two numbers is 8.
x + y = 8
If three times the first number
is equal to the second number.
3x = y
Replace the y in top equation with 3x
x + 3x = 8
4x = 8
x = 2
Substitute x = 2 in first equation
x + y = 8
2 + y = 8
y = 8 - 2
y = 6
{2,6}
Hope this helps :-)
its an obtuse angle so each equation should equal 180
Hint: (9y+7) = 180 and (2y+98) = 180
hope this helps pls mark me brainliest
An example of an additive inverse of a number is:
7 + (-7) = 0
No matter what, your sum needs to be 0, as the inverse of the number is the same number only with a different sum. (for example: -8 & 8, -10 & 10, etc)
hope this helps
