For this problem, if we used b to represent your base angle measurement, you would add 8b+2b and set it equal to 180. This is because the measure of the vertex angle is 8 times the base angle measurement, so we had to multiply b by 8. We also had to add it to the other angle measures, so the other angle measures are represented as 2b since they are the same length. We then have to set this equal to 180 since that measures of a triangle must add up to 180. Then we combine like terms on our “b” side to get 10b=180. Then we divide both sides by 10 and we get b=18, which is the measure of our base angle.
Answer: $25
Step-by-step explanation:
20% = 0.20
125 x 0.20 = 25
$125 + $25 = $150 (the entire bill)
Answer:
It will take 3 hrs and 30 min. Here is why:
Step-by-step explanation:
If 4 miles is in one hour the closest to 14 is 12 without going over. 4 miles per hour times 3 is 12 miles per 3 hours but the issue is how do we find how long the other 2 miles take? Well if we go back to 4 miles per hour we just need to divide both sides by 2. We get 2 miles per half an hour or 30 minutes so adding 12 miles+ 2 miles we get 14 miles. Then adding our time 3 hour and 30 minutes that is our answer!
Answer : It takes 3 hours and 30 minutes for Martha to walk 14 miles.
, the LHS reduces to 0, so 
is a factor of the cubic. You can find the remaining two solutions easily with the quadratic formula.
