Answer:
x=6/7
Step-by-step explanation:
7x÷2+5=8
divide by 2 on both sides:
7x/2+5=8(it's a fraction)
subtract 5 on both sides
7x÷2=3
multiply 2 on both sides
7x=6
divide by seven on both sides
x=6/7
hope this was helpful and the instructions were clear enough!

The answer is a
Step-by-step explanation:
The distance from the near end of the runway to the plane, divided by the altitude is the tangent of (90 degrees minus the angle of depression). Let "d1" be the distance to the near end of the runway, and "d2" be the distance to the far end of the runway. Let "a" be the altitude of the plane.
d1/a = tan(90 - 31)
d1 = a*tan(90 - 31)
d2/a = tan(90 - 23)
d2 = a*tan(90 - 23)
runway length = d2 - d1 = a*(tan(67) - tan(59))
length = 1800*(.6916) = 1245m = 1.2km
the answer is "a"
Answer:
Unitary cost per card= $0.21
Step-by-step explanation:
Giving the following information:
Number of cards per packecge= 25
Total cost per package= $5.25
<u>To calculate the unitary cost of each card, we need to use the following formula:</u>
Unitary cost per card= total cost / number of cards per package
Unitary cost per card= 5.25 / 25
Unitary cost per card= $0.21
