Inot sure if i did it right number 8 i did 2(x+12)=12
2x +144=12
-144
which i got132 divided 2x and i got 69 then i realized maybe i did something wrong and i did a different process but same equation instead multiply 12x2 and subtracted and i got 12 and divided by 2 and got 6 am i doing this right

What is the slope of a line that is perpendicular to y = 3x + 1

Write a corresponding real world problem to represent 2x - 125=400

The sat and act tests use very different grading scales. the sat math scores follow a normal distribution with mean 518 and standard deviation of 118. the act math scores follow a normal distribution with mean 20.7 and standard deviation of 5. suppose regan scores a 754 on the math portion of the sat. how much would her sister veronica need to score on the math portion of the act to meet or beat regan's score?
