Answer:
x = 113
Step-by-step explanation:
( 5x + 685 ) + ( 12x - 106 ) = 2500 ( 685 - 106 = 579)
17x + 579 = 2500
17x = 2500 - 579
17x = 1921
x = 1921 / 17
x = 113
Answer:
-10
Step-by-step explanation:
5 x -2 = -10
From the plot, the masses of the five smallest sodium chloride samples are all 1/4 ounce. Therefore, we can calculate for their total mass by multiplying the mass by 5:
total mass = 1/4 ounce * 5
= 5/4 or 1.25 ounces
We can get the same result even if we compute for the total mass by taking the sum of their masses:
total mass = 1/4 + 1/4 + 1/4 + 1/4 + 1/4
= 5/4 oz.
Answer:
210 mph
Step-by-step explanation:
speed of jet = x
headwind: speed = x - 27
time taken = 1134.6/(x - 27)
tailwind: speed = x + 27
time taken = 1469.4/(x + 27)
same amount of time:
1134.6/(x - 27) = 1469.4/(x + 27)
Cross multiply,
1134.6(x + 27) = 1469.4(x - 27)
1134.6x + 30634.2 = 1469.4x - 39673.8
334.8x = 70308
x = 210 mph
Answer:
Adriana is correct
