Answer:
1/18 or 5.55...% 2nd question: 10,000
Step-by-step explanation:
She has a one in 6 odds for the dices, and every one for those odds she also has 1 in 3 for the spinner, so you just multiply them.
2nd question: you have to do this differently. This one you need to multiply 10 by 10 by 10 by ten, because for each there are 10 1,2,3,4,5,6,7,8,9,0, so there can be ten in each, so you get 10,000
What must be true is the expression will actually be adding 10 + (+ x), because of the two marks you have to make when subtracting by a negative.
The subtraction sign is also the negative sign. So in this case, the expression is also saying -x, which means there is two negative signs.
A double negative is a positive, so in this case the x will be turned to a positive integer.
If this is still too confusing, she can plug in a number to replace x. Let’s try it with -2:
Ex. 10 - (-2)= 12.
The two negative signs turn into one positive sign, AKA an addition sign. So, the above expression can be simplified as 10 + 2, or 12.
