Answer:
8
Step-by-step explanation:
The answer would be 8 because the question would be
24 ÷ x + 5 × 3 + 2=20 right?
The first thing you would want to do is multiply the 5 and the 3 because of PEMDAS which should give you 24 ÷ x + 15 + 2 = 20.
15 plus 2 is 17 and then you would subtract 17 from 20 which would give you 3. So you know know that 24÷x has to be 3 and 24÷3 is 8 so x=8.
Hope this helped!
Answer:
27 and 597
Step-by-step explanation:
To evaluate A5 and A100, substitute n = 5, n = 100 into An , that is
A5 = 6(5) - 3 = 30 - 3 = 27
A100 = 6(100) - 3 = 600 - 3 = 597
Answer:
x = 3.67
Step-by-step explanation:
Simplify both expressions
14x - 18 = 5x + 15
Subtract the bigger (n)x by the smaller
14x - 5x = 9x
Plus the smallest by itself, giving you:
9x - 18 = 15
+18 +18
9x = 33
Simplify ( divided by 3 )
3x = 11
x = 3.67
