Please Halp 0.3x+18=−27

x=-150

Step-by-step explanation:

To solve for x, we would need to use our order of operations.

0.3x+18=-27                       [subtract both sides by 18]

0.3x=-45                              [divide both sides by 0.3]

x=-150

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
