Answer:
s=750+30W, after 14 weeks she has 1170$
Step-by-step explanation:
2x+(x-10)=4
3x-10=4
3x=14
x=4.6 repeating
0.5 of a mile - since 5,280ft = 1 mile and half of 5,280 is 2,640
To answer the problem just add the frequencies that
correspond to email counts that are 19 or fewer. So you're adding the counts
that correspond to 0-9 and 10-19. So the frequency of 0-9 is 4 and the
frequency of 10 -19 is 7. So 4 + 7 = 11
