Answer: simultaneous equation and speed formula lead to:
X = 0.7 - (3 - 4x)/5
Step-by-step explanation: Please find the attached file for the solution.
Well divide the numbers to find the unit rate so it’s 200 meters in a minute I think
So n will be the unknown, and the expression is:
6n = 24
from where we can find the number n:
n = 24/6
n = 4
Answer:
15;9;-8
Step-by-step explanation:
1. 5/3x-3=2/3x+12
x=15 once you combine like terms
2. 5x+35-3x+12=7x+2
2x+47=7x+2
5x=45
x=9
3. 12x+20-3=9x-7
12x+17=9x-7
3x=-24
x=-8
When you divide two fractions, you do Keep, Change, Flip or KCF. So you keep the 3/5, you change the division sign to a multiplication sign, then flip the 3/15 to 15/3. So the new equation is 3/5x15/3. Then you simply the two sides so it becomes 1/1x3/1.....
Meaning the answer is 3.
