Answer:
Step-by-step explanation:
First digit 2,3,4,5 = 4 different digits.
Second digit 2,3,4,5 = 4 different digits.
Third digit = 1,2,3,6,7,9 = 6 different digits.
Total number of possibilities = 4*4*6 = 96
x= -8
Add 13 to both sides.
-13+x= -21
+13 +13
This gives you, x= -8.
d
3/5 is equal to .6. however it can be simplified from 6/10, 9/15, etc
but 4/6 cannot be simplified to 2/5
72.4%
The essay is 25% of your grade, and the rest is 75% of your grade.
25 (3.3/4) + 75 (0.69) ≈ 72.4
Answer is below
21 + 5f = 61 Turn the words into an equation
-21 - 21 Subtract 21 from both sides
5f = 40 Divide both sides by 5
f = 8
