To estimate the sum you must add the estimate of 703 and 620.
700 + 600 (estimated) would be = 1,300
Seven and seven over eight
Answer:
need a little more information
Step-by-step explanation:
System of Equations:
{-2x+2
{-1/3x-3
I used y=mx+b to find the equations
((-4x^3)(y^4))^-3
--------------------------
(2xy^4)^-4
16x^4y^16
=------------------------
-64x^9y^12
-16y^4
=------------------------
64x^5
-y
=------------------------
4x^5
So the final answer is:
-y^4
-------
4x^5
(Btw if "^" is in front of a number, that means it is an exponent, so when your writing this on paper, just write it as a regular exponent without the "^". I had to do that since I'm on a computer.)
Hopefully this was helpful in some way.
