1/3 c equals 3/9 cups
increasing that by 2/9 cups gives total 5/9 cups
Answer: 80 miles for the first ship, and 150 miles for the other.
Explanation:
First thing we should do is correspond each number with a letter:
Let x be the distance travel by ship heading east
Let y be the distance travel by ship heading south
y = x + 70 -- (1)
sqrt(x^2 + y^2) = 170 -- (2)
Subtract (1) into (2):
sqrt(x^2 + (x + 70)^2) = 170
x^2 + x^2 + 140x + 4900 = 28900
2x^2 + 140x - 24000 = 0
x ^2 + 70x - 12000 = 0
(x - 80)(x + 150) = 0
x = 80 or -150
Since the distance for the first ship can’t be negative, therefore, x = 80 -- (3)
Subtract (3) into (1), therefore, y = 150
Hope this helps! :)
Answer:
<h3>
Assuming A, B, and C are collinear and B is between A and C then BC = 35 </h3>
Step-by-step explanation:
Assuming A, B, and C are collinear and B is beetween A and C
AB + BC = AC
2x + 6 + 6x + 5 = 51
8x + 11 = 51
8x = 40
x = 5
BC = 6x+5 = 6×5 + 5 = 35
It would be -8,-12 since we get a prime by dividing by 1/2.
