The three subtraction sentences 12-4=8, 8-4=4, and 4-4=0 can be expressed as a single division sentence. The division sentence 12/4 = 3 means that, starting with the number 12, 4 can be subtracted 3 times to get zero.
Division is repeated subtraction 12 / 4 means how many 4's you can subtract from 12. 12 orange split into units of 4, then how many kids can get 4 oranges 12 - 4 = 8 1st kid 8 -4 = 4 2nd kid 4 - 4 = 0 3rd kid So 3 kid can get 4 oranges each. If we multiply 3 * 4 =12 if each 3 kids get each 4 oranges , then what was the total oranges distributed among kids Now we say that Multiplication is repeated addition. 4 * 3 = 12, 4 + 4 + 4 = 12 Further we can say that Multiplication and division is opposite of each other Like 2 * 3 = 6 6/3 = 2 6/ 2 =3 , Also division and fractions are the same, and symbols can be used interchangeably.

Answer:
X=1, x= -3, x= -1/2
Step-by-step explanation:
okay, so you've got your zeros right here actually. it's very simple, so I'll give you the reader's digest: SET THEM ALL TO ZERO
x-1=0 add your one, so that's x=1
x+3=0, subtract your 3, so that's x= -3
the last one is tricky: 2x+1=0, 2x= -1, but you can go further. divide your two, and you're left with x= -1/2
I hope this helps!!!
Answer: -3/11, -0.29, -2/7
Step-by-step explanation: 3 divided by 11 is 0.27 rounded: -0.27
2 divided by 7 is 0.29 rounded so you have to round to the thousandths so it would be 0.296: -0.296
