There would be a 13 dollar tip if you round it. If you didn't it would be 13.05.
First you would turn the percent into a decimal. You would do this by moving the decimal place to the left 2 places. Then, multiply that by your amount.
Answer: -12r-12
Step-by-step explanation: There is no equals sign so you can't solve it but you can simplify it. You start out with -3(4r-8)-36. Then, you use PEMDAS. (-3×4r)+(-3×-8)-36. Then, it turns into -12r×+24-36. You just continue to simplify until you can't anymore. You end up with -12r-12.
Answer:
12w + 21 =3(4w+7)
Step-by-step explanation:
12 and 21 are multiples of 3 so factor out 3
12w + 21 =3(4w+7)
Answer:
No solution
One solution
One solution
Step-by-step explanation:
Evaluating the tangent function for the two values we obtain the following:
tan 135=tan(135+180)=tan 315=-1
next:
tan -135=tan(180-135)=tan 45=1
thus comparing the two we see that tan 135 is negative while tan -135 is positive
