To find the gradient you do change in y/change in x so...
-12 - 0
————- = -12/4 = -3
0 - - 4
Hope this helps! Any questions let me know :)
To solve this equation from the information given above, I ordered it 5x+12=8x. To solve, I subtracted 5x from each side, canceling the 5x to your left, leaving only the number 12. 8x minus 5x equals 3x. Take 3x and divide on both sides. 3x/3x cancels the 3, leaving 12/3 equals 4. Finally, x equals 4.
A exponent is the smaller number you will see sometimes on the top of a number or to the right of it but smaller than normal font
9/10 is bigger. 10/10 is a whole so in decimal 9/10 is .90
60% = 0.6
12 / 0.6 = 20
answer 12 is 60% of 20
