Multiply dc over one on both sides on the left it’ll be cancelled out with a alone and on the right it would be b*dc - from a freshman
Answer:
Yes, that's right, a change in the direction of motion results in an acceleration even if the moving object neither sped up nor slowed down. That's because acceleration depends on the change in velocity and velocity is a vector quantity — one with both magnitude and direction.

Answer:
1/7
Step-by-step explanation:
They traveled 5/7 of the distance on Saturday.
That left 2/7 of the distance as the remaining distance.
They traveled half of 2/7 of the distance on Sunday.
1/2 of 2/7 = 1/2 × 2/7 = 2/14 = 1/7
Answer: 1/7
X= # students who got lower grades
2x+3= # students with grade A
STEP 1:
Add the two sets above equal to 24.
x + (2x + 3)= 24
combine like terms
3x + 3= 24
subtract 3 from both sides
3x= 21
divide both sides by 3
x= 7 (# students lower than A)
STEP 2:
substitute x value from step 1 to find # grade A students
=2x + 3
=2(7) + 3
=14 + 3
=17 (# grade A students)
CHECK:
x + (2x + 3)= 24
7 + 2(7) + 3= 24
7 + 14 + 3= 24
24= 24
ANSWER: There were 17 students with grade A.
Hope this helps! :)
18 dollars would be the answer
