Answer:
44) 40%
46) 33.3%
68) 8%
74) 72 units
Step-by-step explanation:
44) 20/50= .2= 2-%
46) 5/15= .333= 33.3%
68) 24/300= .08= 8%
74) .8x90= 72
decimal can be made into percents multiplying by 100 (decimal point 2 spots to the right)
percent can be made in to decimals by dividing by 100 (decimal point 2 spots to the left)
Solve the first part of the equation
2.5 X 10 = 25
2.5 X - x = - 2.5x
+ 21
which all added together equals - 2.5x + 46
Now for the second part of the equation
- 3.5 X 3x = - 10.5x
- 3.5 X 20 = - 70
+ 84
which all added together gets you - 10.5x + 14
once you have both parts of the two sides solved, you have to start subtracting from each sides
- 2.5x + 46 = -10.5x + 14
- 46 + 46
- 2.5x = -10.5x + 60
-10.5x +10.5x
-13x = 60
60 ÷ -13x
x = -4.61
I would say 10 because the number 10 is used more than the other numbers in.
