Answer is D. I got -6 and -2 in my answer
Answer:
x = -2.75
Step-by-step explanation:
:D
14 - 3 = 11
11 / -4 = -2.75
It is 120 because you do proportions. 540x=64800 and divide both sides by 540 and x=120
x-12=30
In the problem it states <u>a number (x) decreased (-) by 12. </u> So with that information you're equation should look like x-12. The next part of the problem says that it is <u>equal (=) to 30</u> So now you're equation should be set up as x-12=30. To find "x" you must isolae "x". To do that you would add 12 from the left hand side leaving x and then you would also add 12 to 30. And with that you're left with what x is.
x=42
Hope it helps!
