(Please help-) For every 1 left-handed person, there are 4 right-handed people. If there are 30 students in the class, how many of them should be right-handed?

24 of them should be right handed

Step-by-step explanation:

This is because 1+4=5 so in each grouping of students there are 5 students. Divide the total number of students by the number of students in one group it comes to be 6. So also 6(4) is 24 so your total will be 24.

Answer

23 right handed students

Step-by-step explanation:

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

lo.lll
