Answer:
DE = 21
Step-by-step explanation:
Recall: the ratio of the corresponding side lengths of similar triangles are equal
Given that ∆ABC ~ ∆DEF, therefore,
AB/DE = BC/EF = AC/DF
AB = 8.4
DE = x
BC = 10
EF = 25
AC = 16.5
DF = 41.25
Let's find DE using AB/DE = BC/EF. Thus:
8.4/x = 10/25
Cross multiply
x*10 = 25*8.4
10x = 210
Divide both sides by 10
x = 210/10
x = 21
DE = x = 21
Answer:
M ≥ -5 3/5
Step-by-step explanation:
-5(M+1)≤23
Distribute -5
-5M -5 ≤23
Add 5 to each side
-5M -5+5 ≤ 23 +5
-5M ≤ 28
Divide each side by -5, remembering to flip the inequality
-5M/-5 ≥ 28/-5
M ≥ -28/5
M ≥ -5 3/5
