You would add like terms so it would be 1x then you add 1 to 7 so you would get 8.. the you divide both sides by 1x and you'd get 8=x
Answer:
99
Step-by-step explanation:
That quadrilateral equals to 360. So i had to add the numbers which equal 261. Then i did 360-261=99.
Answer:
55.734 mph
Step-by-step explanation:
Let's call the wind speed x and the time of flight t.
Then, we can write the following equation, knowing that the distance is equal speed times time of flight:
910 = (350+x) * t
660 = (350-x) * t
If we isolate t in both equations and compare its value, we have that:
910 / (350+x) = 660 / (350-x)
(350+x)/(350-x) = 910/660
350 + x = 1.3788 * (350-x)
350 + x = 482.58 - 1.3788x
2.3788x = 132.58
x = 55.734 mph
Answer:
49 1/6 meters
Step-by-step explanation:
P = 2(73/3) + 2(61/4)
= 146/3 + 61/2
= 48 2/3 + 30 1/2
= 48 4/6 + 30 3/6
= 48 + 7/6
= 48 + 1 1/6
= 49 1/6
