It's incorrect because the equation is solve incorrectly the anwer is r= -4

Step-by-step explanation:

Add 4r4r to both sides.

-3r+9+4r=5

−3r+9+4r=5

2 Simplify  -3r+9+4r−3r+9+4r  to  r+9r+9.

r+9=5

r+9=5

r=5-9

r=5−9

4 Simplify  5-95−9  to  -4−4.

r=-4

r=−4

I need help with estimating, then finding the quotient and write the remainder if any as a fraction?
elena55 [62]
When estimating, you want to round the dividend and the divisor to the nearest time table number (i.e. 5700 --> 5400). Finding the quotient is easier when you estimate. Writing the remainder as a fraction is simple. First, get your remainder and your divisor, then make it to a fraction.

ex:

If you get a remainder of 3, and have a divisor if 12, your remainder would be 3/12, or 1/4.
