4 7/15
You can only add fractions if they have the same denominator, which in this case is the 15 and the 5. So you can't add the 1/5 and the 4/15 together just yet because its not the same denominator. Multiply 3/3 to 1/5 to get the same denominator as 4/15, and it would become 3/15 because whatever you do to the top, you do to the top. Add them together and you get 7/15, and then add the whole 4 and you get 4 7/15

Answer:
6.28km
Step-by-step explanation:
Hey,
We know that the circumfrence is the perimetert of a full circle. If we want to find the perimeter of a semicircle all we have to do is find the circumfrence and then divide it by 2 since we want to know the perimeter of half the circle.
Circumfrence is equal to 2πr. Where r is the radius and since we know the radius we an solve for the circumfrence.
2(π)(1km)=2kmπ.
The problem tells us to use 3.14 for pi so let's multiply 2 by 3.14.
6.28km is the answer!

Answer:
n = -9
Step-by-step explanation:
4(0.5n − 3) = n − <u>0.25(12 − 8n)</u>
2n - 12 = n - <u>3 + 2n</u>
2n - 12 = 3n - 3
2n - 3n = - 3 +12
-1n = 9
n = -9
