Answer:
she will need 8.4 so just get 9
Answer: 10
Explanation: This is an equilateral triangle so all the angles are 60° since 180 ÷ 3 = 60.
Work:
60 = 5y + 10
-10 -10
50 = 5y
5 5
10 = y

Answer:
C. 116
Step-by-step explanation:
AC= 58*2= 116
If we have a number represented by n, we have 20 is equal to, so 20=something. That something is "5 less than twice a number". 5 less than something means something-5, and something-5=20. Since 5 is less than twice a number, and twice a number is n+n=2n, we have 2n-5=20
Actually solving the problem, we can start by adding 5 to both sides, resulting in 2n=25. Next, we can divide both sides by 2 to get n=12.5
