Answer:

-2

Step-by-step explanation:

First, distribute. 12r + 16 = -16r - 40

Then get r on one side by adding 16r to both sides then subtracting 16 from both sides.                  28r = -56

Finally, divide by 28 on both sides to get r by itself.

r = -2

Paloma decided to divide 1,292 by 31 using partial quotients. She uses 30 as her first partial quotient. Which are the partial q
Keith_Richards [23]

Answer:Partial quotients Paloma should show in her work are B) 30,10,1.


Step-by-step explanation:

Given : Paloma dividing 1292 (dividend) by 31 (divisor) using partial quotients.

so the easy multiples of 31 are as 31×2=62 ,31×3=93,31×10=310....so on

if she uses 30 as her first partial quotient then 31×30=930, so after subtracting 930 from 1292 we get 362 as new dividend then 31×10=310 is the easiest multiple of 31 so that 362-310=52 as new dividend ,then 31×1=31 subtracting this from 52 gives 52-31=21 which is the remainder.

Therefore, Partial quotients Paloma should show in her work are 30,10 and 1.

The independent variable is the variable that the researcher varies or changes or manipulates in the course of the experiment. The independent variable usually have a direct effect on the dependent variable.

With the passage of time, the level of concentration increases. This means that time is the independent variable and concentration is the dependent variable.
