Answer:
24 right handed students
Step-by-step explanation:
1. Out of every 5 students, 4 are right handed and 1 is left handed. We can say that 1/5 of the class is left handed.
2. Multiply 30 by 1/5 to get 6 left handed students in the class.
3. Take the 30 students in the class and subtract the 6 left handed students.
4. The remaining 24 students must be right handed.
Answer: x= - 7/5
Step-by-step explanation:
did the problem
If John had to mow 8 lawns, but he forgot to mow 2 lawns, we have to subtract 2 from 8 to see how many lawns he actually mowed.
8-2=6
John mowed 6 lawns!
For each lawn John mowed, he earned 3 dollars. So, we have to multiply the number of lawns he mowed, 6, by the amount of dollars he earned per lawn, 3. Multiplying 6*3 is the same as adding 3+3+3+3+3+3!
6*3=18
John earned $18!
Hope I helped! :)
No, not at all.
The general quadratic equation is
Ax² + Bx + C = 0 .
The roots are real only if (B² - 4AC) is not negative.
That means if you graph it, it touches or crosses the x-axis.
If the graph is up in the air and never touches the x-axis,
then it has no real roots.
