Answer:
The number of times Abigail is faster on her skateboard than she is walking is 2 times faster
Step-by-step explanation:
Let the distance to Abigail's home = D
The distance Abigail had traveled before hr skateboard broke = 2/3·D
The distance from home where the skateboard broke = D - 2/3·D = 1/3·D
The time it took Abigail to walk the 1/3·D home = Twice the time it will take her if she was on her skateboard
Let the time it will take Abigail to travel the 1/3·D home on her skateboard = t
Therefore;
The time it took Abigail to walk the 1/3·D home = 2 × t
The speed of Abigail walking, = Distance/Time = 1/3·D/(2 × t) = D/(2·t)
The speed of Abigail skateboarding, = Distance/Time =D/t
The ratio of the speed of Abigail skateboarding to the speed of Abigail walking =
Therefore, Abigail is two times faster on her skateboard than she is walking.
Answer:
4
Step-by-step explanation:
30x1/3=10
10x2/5=4
First find out who plays sports then find who plays soccer from the sports.
When solving for a variable, you want to get it isolated (i.e. alone). Here are the steps to do this equation...
1. Given: kx-3=5
2. Add three to both sides to remove the -3, and this gives you kx=8
3. Since the x is being multiplied by k, you want to do the inverse and divide both sides by k, and this gives you x=8/k
So this means that your answer is D

<h3>What is an equation?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 is an equation.
We have,
Number of multiple choice questions = M
Number of open response questions = N
We can make two equations.
M + N = 36 _______(1)
3M + 5N = 120 ______(2)
From (1) we get,
M = 36 - N ______(3)
Putting (3) in (2) we get,
3(36 - N) + 5N = 120
108 - 3N + 5N = 120
2N = 120 - 108
2N = 12
N = 6
Now,
Putting N = 6 in (3) we get,
M = 36 - 6
M = 30
Thus,
The number of multiple-choice questions and open-response questions is 30 and 6.
