Since she took away $93, -93 would represent it!
Hope this helped!
CU said this before, 21.
Wow! You make it look so easy, Chris! Nice!!!!
Like 4/2, you divide the numerator by the denominator.
2 divided by 7/3 would be 2 times 3/7 which is 6/7.
Oh~~~ It makes so much more sense now. Thanks, EP!
Yes, definitely!!!!
Nice, Chris!
A dilation means, increasing or decreasing with a scale factor of--. For example, if we were dilating a line 3 inches long by a scale factor of 2, then the line will become 6 inches long. Use this to find the answer.
Hint:
We can square root, cube root, etc. or add an exponent to simplify all of the numbers. Then, we can get rid of the fraction easily. Try it out, and if it is still confusing, I will give you another hint!
We can place a 0 in the fourth box that will be empty.
If we know this, the problem becomes very simple. There are fourr choices of digits for the first box, three for the second, two for the third, and one for the last. 4*3*2*1=24 total options.
