3/10 = 30%
30% of students bring their lunch.
I'm pretty sure its 100 because if she gave each of her 19 students 5 invitations that equals 95. (19×5=95) And She had 5 leftover equals 100. (95+5=100)
Answer: second option.
Step-by-step explanation:
You need to descompose the radicand 8 and the radicand 50 into their prime factors:
Then you can rewrite the expression:
Since:
You can simplify the expression:
As the indices and the radicands are the same, you can make the addition:
Answer:
1. 3x - 24 = 6
2. 3x = 30
3. x = 10
Step-by-step explanation:
1. 3 times x is 3x, 3 times 8 equals 24, hence 3x - 24
2. Add 24 to both sides to get rid of -24, getting you 3x = 30
3. Divide by 3 on both sides to even out the x, giving you x = 10
