An equation is:
2(x+3)-7=9
Distribute the 2
2(x)+2(3) -7=9
2x+6-7=9
Combine like terms
2x-1=9
Add one to both sides
2x-1+1=9+1
2x=10
Divide both sides by two to isolate the variable.
2x/2=10/2
x=m
Answer: 70%
Step-by-step explanation:
2 quarters and 2 dimes is 70 cents. 100 cents total in a dollar so no need for further calculation. 70%
72 people can fit in the biat bc if u Add 45+27 7+5=12 so u will put the 2 in the tens and 4+2+1= 7 so the anwser is 72
Approximately 95% of a normal distributions falls within 2 standard deviations of the mean.
There is a total of 10 marbles, of which 5 marbles are red.
![P(red)=\frac{5}{10}=\frac{1}{2}](https://tex.z-dn.net/?f=P%28red%29%3D%5Cfrac%7B5%7D%7B10%7D%3D%5Cfrac%7B1%7D%7B2%7D)
Therefore the second choice is the correct answer.
