Okay. So, what you do is subtract the negative number from the positive number. Let’s find the lowest common multiple of each number. The lowest common multiple (LCD) is 6. So we set this problem up as 2 3/6 - 1 1/6. When we subtract both numbers, you get 1 2/6. or 1 1/3 in simplest form. Now, you subtract again. Because 1 3/4 is greater than the number we are subtracting from, which is 1 1/3, the answer will be negative. The LCM of 3 and 4 is 12, so 12 will be the LCD. Let’s subtract to get our negative difference. 1 9/12 - 1 4/12 is 5/12. Plug in the negative symbol and you have -5/12. There. The answer is -5/12.
Answer:
3x + (-2) = 2x + 4
Step-by-step explanation:
Look at the first part. There are three boxes with "x" in them and 2 boxes with "-1" in them.
Since there are three boxes with "x", that means that the first number in the equation will be 3x, making A and B incorrect answers.
Now look at the two "-1" boxes. If the answer was C, then the boxes would be yellow and have 1 on it like the ones on the right, making C an incorrect answer.
This leaves you with D, or 3x + (-2) = 2x + 4
Hope this helped!
Answer:
x = 3
Step-by-step explanation:
15 - x = 2(x + 3)
15 - x = 2x + 6
15 - x - 2x = 6
-x - 2x = 6 - 15
-3x = 6 - 15
-3x = -9
x = 3
So you are looking for the volume of the sand box so what you need to do is multiply the info you got. 10x8x1.5=120
so your answer would be 120 sf
