Ava's sister paid a 4.5% annual interest rate
Her sister paid $54 more than she borrowed, divide that by 3 (years till she paid)
54/3 = 18
That's $18 for every year she'd had the $400 loan out, divide it by 4 to get the percentage
18/4 = 4.5/100 = 4.5%
Answer:
48 degrees
Step-by-step explanation:
Because the angles are on the same line (the vertical one) we know that both of them would add up to 180 degrees. So first we subtract 180-32 to get 148. Now we know that 3h+4=148. To solve for h, our first step would be to subtract 4. Now the equation is 3h=144. Lastly, we divide both sides by 3 to get h=48.
3/4+3/4+3/4+3/4 is the answer.
So, we know the center of this circle is at 6, -2, and a point on the circle is at 3,4. Now, from the center of the circle, to a point on the circle, is how long the
radius is, therefore, the distance from 6, -2 to 3,4 is the radius "r", thus,

For the answer to the question above,First 2+3x= 18
3x= 18-2
3x= 16
X= 16/3
Let's try to check: 2+ 3(16/3)= 18
2 + 16= <u><em>18</em></u>
The answer is for this question is <u><em>16/3 or 5 1/3.</em></u>
I hope my answer helped you. Have a nice day!
