-4/5 = -16/20, so the new expression is (-16/20)+(3/20)
then, -16 + 3 is -13, so the solution is -13/20
I know its a long problem but i have to shiw how i got my answer.
8^15 ÷ 1/8^3 = 8^15 x 8^3=8^18
The answer is 1 Bcuz u have to first plug in -4 for f then solve the equation by adding like terms and dividing
I don't quite understand the ten strategy, or what EXACTLY you're asking. But, what you can do is when you add a one digit number plus a nine, just change the nine to a ten and subtract one. It is very easy. So, 7+10 equals 17, subtract one and you get 16 which is 7+9. It is always one less than anything plus 10.
