30 % because 55 - 30 is 25 and the nearst tenth is 30
you can estimate 17/18 - 3/7 = 65/126 to estimate the answer to 70/130. i think that's what you are asking
How do we graph anything? Make a table of values for x and y and then plot each point. After plotting each point on the xy-plane, connect each point with a straight line or curve (depending on the function).
In this case, we must first isolate y.
y = (-4/3)x + 8y
y - 8y = (-4/3)x
-7y = (-4/3)x
y = (-4/3)x ÷ (-7)
y = (4/21)x
Now follow the steps above.
