Step-by-step explanation:
.3f+1 = .2f-4.5
1. Subtract .2f both sides
.1f+1 = -4.5
2. Subtract 1 from both sides
.1f = -5.5
3. Divide .1 both sides
f = -55
To check plug in -55 to all the f’s and both sides should be equal.
Hope this helps!
By not using the digit 0, John has 9 digits left to choose from. By not using the letter m, John has 25 letters left to choose from.
The password pattern is <letter><letter><digit><digit><digit><digit>. Use the Multiplication Principle:
25 x 25 x 9 x 9 x 9 x 9 = 4,100,625
They definitely can be positive they can be negative and they can have an absolute value but I would choose they both can be positive and negative
