Answer:
Therefore, 9 darts did not hit the bull's-eye.
Step-by-step explanation:
Equivalent ratio states that the two ratios are express the same relationship between numbers
As per the given statement: Curtis threw 15 darts at a dashboard.
40% of his darts hit the bull's eye
then;
60 % of his darts did not hit the bull's eyes.
By definition of equivalent ratio;
x/15= 600/100
Multiply both sides by 15 we have;
x= 60/100 *15= 60*15/100= 900/100= 9 Darts
9 did not hit the bulls eye
If 40% did hit the bulls eye, 100-40 = 60% did not hit the bulls eye
15 * 60%
15 *.6
9
x = -2, y = 5, z = 7
Let these 3 numbers be x, y, and z
x is the first
y is the second
z is the third number.
Then:
x + y + z = 10
2*y - x = 12
x - y + 2z = 7
x = 2y - 12
(2y - 12) + y + z = 10
and
(2y - 12) - y + 2z = 7
so
3y + z = 22
y + 2z = 19
y = 19 - 2z
3*(19 - 2z) + z = 22
57 - 6z + z = 22
57 - 5z = 22
35 = 5z
z = 7
y = 19 - 2*7 = 19 - 14 = 5
x = 2y - 12 = 2*5 -12 = 10 -12 = -2
Answer: A. The vectors point in the same direction
