If the number is x, then 2*(x+3)-7=9 due to that you subtract the result of double of x+3. Adding 7 to both sides, we get 2*(x+3)=16. Next, we divide both sides by 2 to get x+3=8 and subtract 3 from both sides for our final result, x=5
Answer:
y - 0 = -3/4(x - 8)
y = -3/4x + 6
Step-by-step explanation:
Answer:
55°
Step-by-step explanation:
Using cosine law
67² = 74² + 14² - 2(74)(14)cos(L)
cos(L) = 169/396
L =55.18378419
As you can see, the area of the scarf is equal to the area of the rectangle minus the area of the 2 semi-circles (which form a circle)
Now, we calculate the area of the rectangle : 28 x 15 = 420 in2
The diameter of the circle is 15in -> The radius = 15 : 2 = 7.5in.
We now find the area of the 2 semi-circles : 7.5 x 7.5 x 3.14 = 176.625 in2
So, the area of the scarf is : 420 - 176.625 = 243.375 in2
