Answer:

The answer would be 9 75/50 which would equal 9 3/2.

Step-by-step explanation: First you would multiply 4/5 by 10 and 7/10 by 5 because the common denominator is 50. Next, you would add it together. Finally, you would reduce that to 9 3/2 I am pretty sure.

Answer:

Check boxes 3, 4, 6, and 8.

Step-by-step explanation:

We have the equation:

$y=-3x+2$

And we want to select all equations that are perpendicular to the above equation.

Remember that perpendicular lines have slopes who are negative reciprocals of each other.

Therefore, the slope of our equations must be the negative reciprocal of -3.

The negative reciprocal of -3 is 1/3. We flipped -3 to -1/3, and then multiplied by a negative.

Therefore, any equation with a slope of 1/3 is perpendicular to our original line.

Therefore, we will check boxes 3, 4, 6, and 8.
