Answer:
8b+7p=20
p = 2b
Step-by-step explanation:
Given that there is a constant speed of 8 km per hour and the number of hours be b so here 8b signifies the distance
Now on the other hand there is a constant speed of 7 km per hour and the number of hours be p so here 7p signfies the distance
So the total distance would be
= 8b + 7p
And, the total km is 20
Now the whole equation would be
8b + 7p = 20
Also it is mentoined that for getting into the park it is twice for getting into the beach
So, it would be
p = 2b
Therefore the system of equations are as follows
8b+7p=20
p = 2b
Answer:
That would be 4x - 3y + 5

Answer:
C. Student 3
E. Student 5
Step-by-step explanation:
we know that
The formula to calculate the midpoint between two points is equal to

<u><em>Verify the midpoint of each student</em></u>
student 1
we have the endpoints
(-9,0) and (11,-8)
substitute in the formula


so
The midpoint is not (-1,4)
student 2
we have the endpoints
(-6,-1) and (4,-7)
substitute in the formula


so
The midpoint is not (-1,4)
student 3
we have the endpoints
(-5,2) and (3,6)
substitute in the formula


so
<u>The midpoint is equal to (-1,4)</u>
student 4
we have the endpoints
(-3,10) and (5,-2)
substitute in the formula


so
The midpoint is not (-1,4)
student 5
we have the endpoints
(0,-3) and (-2,11)
substitute in the formula


so
<u>The midpoint is equal to (-1,4)</u>
therefore
Student 3 and student 5
