A) Sumaya adds the number of page and number of the pages she already read too gets 330 and -20 is the number page she wants to read.
b) 150 = 20d the answer is about 7 to 8 days
explain :
Zumaya adds 240 page and 90 page she read together. the reason it's wrong because the book only had 240 page, you can't add the page you had read together you need to subtract the 240 to 90 to get 150 to know how many pages she has to read.
Answer:
f=7/3
Step-by-step explanation:
from the figure it can be deduced that x=3 and
y=7
so: y=f(x) → 7=f(3)
put f to the first member: 7=3f → 3f=7 → f=7/3
(I hope that's right)
Answer:
0.3
Step-by-step explanation:
total:16.3
20*0.8=16 (amount she will use)
16.3-16=0.3
The unit rate is 2:1 because if you divide 30 by 15 it is 2 which means 2 for 1.
