18 - 4 - 2/7j - 6/7j + 5 =
18 - 4 + 5 - 2/7j - 6/7j=
19 - 8/7j
Answer:
j(x) = 150x
Step-by-step explanation:
f(x) goes up 45x
g(x) goes up 140x + 8
h(x) goes up 3/4x + 12
j(x) goes up 150x
j(x) has the highest multiple to be multiplied by I believe.
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!
12.7 rounded to the nearest whole number is 13. =)
