Y = 4
3x + 4x = 43
3(9) + 4x = 43
27 + 4x = 43
4x = 43-27
4x = 16
16/4 = x
4=x
x=4
Step-by-step explanation:
x=54
use pyth then the other line = 15
then 15÷90 = 9÷x
then x = 54
5 teachers and 10 tutors because we can make a proportion:
3/75=x/120, and when you cross multiply and solve for x you will get 4.8, but there can't be 4.8 teachers so we can say 5 teachers (round). Do the same for tutors: 6/72=x/120, x would equal 10.
Hope this helps!
