Answer:
The slope will be 1/2.
Step-by-step explanation:
Sine the lines are perpendicular, the slope of the green line will be the negative reciprocal of the slope of the red line. To find the negative reciprocal of -2, first change the sign. Since the slope is negative, make it positive 2. Then to find it's reciprocal, divide 1 by your answer. 1 divided by 2 is one half, s that is your answer.
Answer: 4/5
Step-by-step explanation: It is 8/10, but if you simplify it, it is 4/5.
Let's set these equations up first before anything.
4/5 mi and 1/20 mi per hour.
Multiply 4/5 by a number that will get your denominator (5) to 20.
5 x 4 is 20, so multiply 4/5 by 4.
16/20 miles, or, 16 hours, since 1/20 mi is made per hour.
Your answer is 16 hours.
Hope this helps :)
<span>Let's call these friends by their first initial:
K = Kiana, G = Gary, M = Monty, W = Willa
Now we can convert the question to a system of linear equations:
Gary has 3 cards more than Kiana, so G = K + 3
Monty has 7 cards more than Kiana, so M = K + 7
Willa has twice as many cards as Monty, so W = 2M = 2(K + 7) = 2K + 14
74 cards given out = all the friends combined, so
74
= K + G + M + W
= K + (K + 3) + (K + 7) + (2K + 14)
= 5K + 3 + 7 + 14
= 5K + 24
50 = 5K
10 = K, so Kiana had 10 cards
G = K + 3 = 13, so Gary had 13 cards
M = K + 7 = 17, so Monty had 17 cards
W = 2M = 34, so Willa had 34 cards
Checking our work, 10 + 13 + 17 + 34 = 74 cards total.</span>
