Answer:

24

Step-by-step explanation:

Equilateral has 3 angles that add up to 180, and all angles are equal

3(2x+12) = 180

6x+36 = 180

180-36 = 6x

aliya0001 [1]
I assume you mean 5/8 of a pound not 58 pounds. In that case convert your total number of pounds into eights to make it easier to calculate. 5 pounds is equal to 40/8 pounds of cheese. Now divide this by 5/8. That equals 8. SO you can make 8 batches.

romanna [79]

Answer:

  • (a)  15,600 s
  • (b)  Evelyn

Step-by-step explanation:

(a) 1.56×10^4 = 1.56×10000 = 15,600

(b) There are 3600 seconds in an hour, so Andrew's time was

  15600 s/(3600 s/h) = 13/3 h = 4 1/3 h

1/3 hour is 20 minutes, so Evelyn's time of 4:16 is shorter than Andrew's time of 4:20.

22+(30-4) ÷2 And 18+(22-4) ÷6
schepotkina [342]

22 + (30 - 4) divided by 2

30 - 4 = 26

26/2 = 13

22 + 13 = 35

35

18 + (22 - 4) divided by 6

22 - 4 = 18

18 divided by 6 = 3

18 + 3 = 21
