Answer:
a = 1
Step-by-step explanation:
7*9 =
We can rewrite 9 as 10-1
7 * (10-1)
7 * 10 - 7*1
a = 1
So, because there is an exponent, we do that first. 2*2=4 then we take 3 from four, and put x to the side. We then have 1. Subtract 27 from 1. You -26. Add you x back in. You then have -26x.
The answer is -26x.
3/4 + 4 1/2 = 5 1/4
If you mean that the dictionary is 41/2 then the answer = 3/4 + 20 1/2 = 21 1/4. That's a big diction though and not likely measured correctly.
Does it tell you what process to use
Like graphing Substitution or elimination
Sorry :l
