Answer: 3/4
Step-by-step explanation: At the top you can see it is dividing by two so whatever you do to the numerator has to be done to the denominator. 6÷2=3 and 8÷2=4.
Hope this helps!
If 6.3 is added to both sides, y=8.5

Answer:
l = 10.5 cm and A = 21 cm2
Step-by-step explanation:
Area is w*l
Perimeter is 2(w+l)
Replacing the information known in the problem you can get the length with the perimeter
P = 2(w+l)
25 = 2(2+l)
12.5 = 2 + l
10.5 cm = l
with the length now you can find the area
A = w*l
A = 2*10.5
A = 21 cm2
Step-by-step explanation:
Let w be the speed of wind and v be speed of airplane without wind.
(A)
(B)
(C)
Adding equations A and B, we get :
(v - w) + (v + w) = 350 + 525
2v = 875
<u>V = 437.5 mph</u>
