Hi!to calculate a square root without a calculator is to see if you can get to that whole number by squaring smaller numbers,or multiplying a smaller number by it self.
3/5 + 5/7 = 1 11/35 - 1/5 = 1 4/35 which is your final answer.
3x+6y=12
-3x -3x
6y=-3x+12
*divide by 6 on both sides*
y= -1/2x+2
Slope: -1/2
Y-intercept: 2
Add -15.9 to both sides so it’ll look like 3.7x=18.87
First blank is foreign then the is add then the next one is 28
