Answer:
Scalene Acute
Step-by-step explanation:
All the sides have different lengths, and all the angles are less than 90˚ so I'm pretty sure it's a scalene acute triangle.
Answer:
7.5 in
Step-by-step explanation:
Y = mx + b
1.) -6x + y = 4
Move variable x over to the other side by adding 6x.
y = 6x + 4
2.) -y - 2x = 4
Move variable x over to the other side by adding 2x.
-y = 2x + 4
Divide the whole thing by -1 because y needs to be positive and alone.
y = -2x - 4
Answer:
2 hours
Step-by-step explanation:
So lets say the distance one boy travels is 'x', you can set up an equation like this:
x + x + 1 = 7
2x +1 = 7
2x = 6
x = 3
So one boy walks 3 miles in one hour, and the other walks 4 miles in one hour.
Therefore, their speeds are 3 miles per hour and 4 miles per hour respectively.
