Answer:
x ≥5 or 5 ≤x
Step-by-step explanation:
2x ≤ 5x - 15
Subtract 5x from each side
2x-5x ≤ -15
-3x ≤-15
Divide each side by -3, remembering to flip the inequality
-3x/-3 ≥ -15/-3
x ≥5
Check x=10
2*10 ≤5*10 -15
20 ≤50 -15
20 ≤35
True
Based on the number of families that left and the number in total on that block, the expected number of families gone on the other block is <u>25 families. </u>
On the first block, the proportion of families that is gone is:
<em>= Number of families gone / Total number of families on block</em>
= 5 / 12
If there are 60 families on a block, the number gone would be:
<em>= Proportion of families gone x Total number of families </em>
<em>= 5/12 x 60</em>
= 25 families
In conclusion, 25 families would be gone
