I quickly did this on paper and here is my answer I’m not 100% sure I’m correct but here it is
In 1 hour the boats will be 15 miles apart. In 3 hours the boats will be 45 miles apart.
Hope this helps :D
First of all you have to make them equal to each other. What I mean is the following
3x+20=2x+40
Then you should just solve for x
Answer:
28
Step-by-step explanation:
x = 2 point questions, y = 3 point questions
x + y = 40
2x + 3y = 92
Solving this we get x = 28, y = 12 so the answer is 28.
Answer:
13
Step-by-step explanation:
x y
y=1/2x+3 and passes through the point (10,-5) 10 = x and -5 =y 1/2(10) - this mean times
-5 = 1/2(10) +3
1/2(10/1) = 1 x 10 and 2 x 1 = 10/2 = 5
-5 = 5 + 3 = 7
-5 = 7 + 5 + 7
+5 +5
= 13
(I wish You'll understand)
