Answer:
(4,-3)
Step-by-step explanation:
Multiplying the bottom equation by -6, we get -6x+12y=-60.
Adding this to the first equation gives 15y=-45, and thus y=-3.
So, it follows that 6x+3(-3)=15, and thus x=4.
Answer:
14
Step-by-step explanation:
Firstly, we need to subtract the amount she earned from walking the dog ($9.00) from the end total ($16.00). This leaves us with $7.00.
Since she spent exactly<em> </em><em>half</em> of her weekly allowance, we must multiply the remaining $7.00 by 2. This leaves us with our final answer of $14.00.
Formula to find the arc length is:
Where, s= arc length,
r = radius of the circle
\theta = central angle in degrees.
According to the given problem, \theta= 150 and r =2.4.
So, first step is to plug in these values in the above formula to get the arc length.
=
So, arc length is 
.
