A whole number, one that isnt a fraction
Answer:
AC = 7.73
Step-by-step explanation:
∵ DE // AC
∴ m∠BDE = m∠BAC ⇒ corresponding angles
∴ m∠BED = m∠BCA ⇒ corresponding angles
∵ ∠B is common angle
∴ Δ BDE is similar to Δ BAC
∴ BD/BA = DE/AC = BE/EC
∵ AD = 6 and AB = 17
∴BD = 17 - 6 = 11
∵ DE = 5
∴ 11/17 = 5/AC
∴ AC = (5 × 17) ÷ 11 = 7.7272 ≅ 7.73
Answers:
32/100 = 16/50 = 8/25
72/100 = 36/50 = 18/25
43/100 = 43/100
29/100 = 29/100
The answer is a=5 because you have to distribute the 3 so then it would be 3a-12+1=9-a then simplify that to 3a-11=9-a then it would be 4a-11=9 then it would be 4a=20 and then divided 4 by 20 and you get 5
The first is 4. the second is 6.
