Answer:

You do 2/3 times 30d minus 2/3 times 15. That will give you 20d - 10

Step-by-step explanation:

(2/3x30d) - (2/3x15) = 20d - 10

Answer to the question

Zepler [3.9K]

Answer:

x = 23

Step-by-step explanation:

AE = EC

so, 5x + 3 = 118

5x + 3 = 118

Bring +3 to the other side so -3

5x = 118 - 3

5x = 115

Bring 5 to the other side so:

x = 115 ÷ 5

x = 65
