-10 1/5 is the answer for this mathematical equation, which is basically finding the value of x by reversing it.
They have sold ten full cases
but have sold 10 and a half cases in total
The speed of wind and plane are 105 kmph and 15 kmph respectively.
<u>Solution:</u>
Given, it takes 6 hours for a plane to travel 720 km with a tail wind and 8 hours to make the return trip with a head wind.
We have to find the air speed of the plane and speed of the wind.
Now, let the speed wind be "a" and speed of aeroplane be "b"
And, we know that, distance = speed x time.
Now at head wind →
So, solve (1) and (2) by addition
2a = 210
a = 105
substitute a value in (1) ⇒ 105 + b = 120
⇒ b = 120 – 105 ⇒ b = 15.
Here, relative speed of plane during tail wind is 120 kmph and during head wind is 90 kmph.
Hence, speed of wind and plane are 105 kmph and 15 kmph respectively.
Answer:
Step-by-step explanation:
1. y - 2 = -3(x - 4)
y - 2 = -3x + 12
y = -3x + 14
2. y - 6 = -1/2(x + 5)
y - 6 = -1/2x - 5/2
y - 12/2= -1/2x - 5/2
y = -1/2x + 7/2
Answer:
<em><u>1) Sam's Club is better because the price for 10 cans at the village market would be $6.20 versus $4.70 from Sam's Club</u></em>
<em><u>2) 420 people with 210 per hour</u></em>
<em><u>3) It would be more beneficial to buy apples from the Quick Market considering the explanation below.</u></em>
<em><u>4) 396 quarts per hour and a daily rate of 792.</u></em>
Step-by-step explanation:
1) $3.10 x 2 = $6.20
2) 70 x 6 = 420
so, 210 per hour
3) $1.05 divided by 3 is $0.35 per apple at the Quick Market
$2.55 divided by 5 is $0.51 per apple at the Stop and Save.
4) take 330 and divide by 10 to get the amount per hour which is 33 quarts per hour.
330 + 33 + 33 = 396 for 12 hours
396 x 2 = 792 for one day.
