Answer:
Average speed(S) is given by:
....[1]
where,
D is the total distance and t is the time.
As per the statement:
A gazelle that runs 140 meters in 5.0 seconds.
⇒D = 140 meters and t = 5 seconds
Substitute in [1] we have;
Simplify:
⇒S = 28 m/sec
Therefore, average speed of a gazelle is, 28 m/sec
Answer:
Step-by-step explanation:
9y = 423
We move 9 to the other side and divide by 423.
y = 423/9
y = 47
Our answer is 47.
Equation B: c = 3d + 5
Which of the following is a step that can be used to find the solution to the set of equations?
2d + 1 = 3d + 5
2d = 3d + 5
2d + 1 = 3d
2d + 5 = 3d + 1
Answer:
The correct option is 1.
Step-by-step explanation:
The given set of equations is
Equation A: c = 2d + 1
Equation B: c = 3d + 5
Using equation A and equation B, equate the value of c.
The value of d is -4. So the value of c is
The equation 2d+1=3d+5 is used to find the solution to the set of equations, therefore the correct option is 1.
Answer: 2 units
Step-by-step explanation:
Given that :
Length of of line segment (AB) = 18 Units
d = distance between point A and successive notch
Number of notches between point A and B = 9
If the length of line AB = 18 units and the number of notches between point A and B = 9
Then distance d, between successive tick marks :
Length of Line segment / number of notches or tick marks between A and B
= 18 units / 9
= 2 units.
Hence distance between tick marks on the number line is 2 units.

Answer:
x=10
Step-by-step explanation:
3(4x-12) = 84
Divide each side by 3
3/3(4x-12) = 84/3
4x-12 =28
Add 12 to each side
4x-12+12 = 28+12
4x= 40
Divide each side by 4
4x/4 = 40/4
x = 10
