Let the distance of Judy from intersection is x and distance of Jackie from intersection is y.
We convert the given information to equations, step by step.
Point 1: When Jackie is 1 mile farther from the intersection than Judy.
This means y is 1 mile more than x.
So,
y = 1 + x
Point 2: The distance between them is 2 miles more than Judy’s distance from the intersection.
Distance between is x+ y.
So, x+y is 2 miles more than y.
x+y = y + 2
⇒
x = 2
From point 1 we have:
y = 1 + x = 1+ 2 = 3
So,
Distance of Judy from intersection is 2 miles and distance of Jackie from intersection is 3 miles.
Answer
we know that all of these angles sum is 180 so therefore . . .
90 + 39 + 3x = 180
(90+39)=
129 + 3x = 180
(180-129) =
3x = 51
(51/3) =
x = 17
Hope this helps! Have a good day and remember to be tiger fierce!! :)
I think answer should true please give me brainlest I hope this helps let me know if it’s correct or not okay thanks bye
Answer:
Step-by-step explanation:
There are 3 blue, 5 red and the total of 8 marbles.
<u>Two different colored marbles are:</u>
- blue, then red or red, then blue
<u>Find the probability of each case:</u>
- P(b, r) = 3/8*5/7 = 15/56
- P(r, b) = 5/8*3/7 = 15/56
<u>Required probability is:</u>
- P(different color) = 15/56*2 = 15/28
