For #30 I ended up doing a lot of adding & if I’m correct it would take about 3 to 3 & 1/2 years for Marshall & Jim to end up with the same salary. So if I’m correct the equation would be the salary + the raise. So it would be something like s + r =x. X equals the total amount of the salary + the raise put together. For #32 I wrote it down multiple times to make sure I get it right. I ended coming up with 46<-8x8<-6x. I tried figuring out the answer to that but I didn’t understand so I went on Socratic & it said there was no solution. Yeah Sorry I couldn’t help with the other 2. I tried my best here.
Let's simplify step-by-step.23.6−7.1a−4.2b−(5.8b−9a)Distribute the Negative Sign:=23.6−7.1a−4.2b+−1(5.8b−9a)=23.6+−7.1a+−4.2b+−1(5.8b)+−1(−9a)=23.6+−7.1a+−4.2b+−5.8b+9aCombine Like Terms:=23.6+−7.1a+−4.2b+−5.8b+9a=(−7.1a+9a)+(−4.2b+−5.8b)+(23.6)=1.9a+−10b+23.6
