0.75*16=12 She made $12 in total :)
hope it helps:))
So what you do,is you add them together to get 13/10 but then you can also simplify it but you can keep the answer to 13/10
One solution was found : t ≤ -13 (number 4)
Pull out like factors :
-3t - 39 = -3 • (t + 13)
Divide both sides by -3
Remember to flip the inequality sign:
Solve Basic Inequality :
Subtract 13 from both sides to get t≤−13
