On average, 2 will fall apart. We can tell this by making a proportion.
1/20 = x/40 ---> cross multiply
1*40 = 20*x ---> multiply
40 = 20x ----> divide by 20
2 = x
Answer:
A. 2x, -4y, and 8
Step-by-step explanation:
If there is a minus sign in front of the 4 (-), add that to the expression. What you are just simply doing is separating the numbers up. For example:
12x - 8y + 4x
Now here, you have two of the same variables (x, y, etc). So, what you do is look at the last number that has the same variables, which is 4, and look at what the problem you will be solving, which is addition. So, very simply, you add then together!
12× + 4× = 16×
As you can see I kept the same variable. This is because, well, it is the same! Simply, just substitute in the 16× with the 8y. Now here is the tricky part, for some people. Do you see that there is a negative sign in front of the 8 (-)? Well! You have to substitute that in with the expression. No adding this or anything, just simply slide it next to the 16× because, we can not add nor subtract it with the 8y just because it has a different variable.
Your example answer would be: 16× - 8y
Hope this helps!
P.S. if you think this helped you at all, Brainliest me if ya want to. Have a great day!
It would be 105 students because you would divide the 280 students into 8 and then get 35, then multiply that by 3 representing the 3/8s of the students

Answer:
21 pacientes tienen problemas cardíacos de los 70 pacientes diagnosticados
Step-by-step explanation:
Paciente con problema cardíaco del total de pacientes diagnosticados = 30%
Total de pacientes que van al hospital en un día = 70
El total de pacientes con problemas cardíacos entre los 70 pacientes diagnosticados es
