Solution: Let x be the height of a student in Marta's class.
The mean height of 18 students in Marta's class is 60 inches
We know that:




Therefore, the total measure of all 18 student's heights is 1080 inches
Answer:
30
Step-by-step explanation:
Supplementary angles add to 180°.

Let t = total number of cans they collected.
(65/100)t + (2/10)t
We can now add the two algebraic fractions.
LCD = 100
See picture.
61.) First you have to think there are 36 packs, 12 cards in 1 pack and 2 stickers in one pack. SO you have to multiply 36 by 12 and 2 by 36. Your answer for 61 will be (36 x 12) + (36 x 2)
Hopefully this helps.
I believe that the answer is 70. I hope I helped! The reason I say this is because BD is half of AE and 35+35=70 :)
