1+1=2 and it needs to add up to 4 so you add in another 2 in the only place left for it to go which is in the tens place because the first and last number have to be the same and 0 has to go in the hundreds place.

Mean of 6 numbers is 41. Remove one number and the mean of the five numbers is 46. What is the unknown number

Alex17521 [72]

Answer:

- 16

Step-by-step explanation:

This is very tricky. Be careful how you do it.

The total of the six numbers is 6*41 = 246

The total of five numbers = 5*46 = 230

What have you you removed to make the number average go up with a smaller sample? The answer is a negative.

230 - 246 = - 16

Solve for x and find the measure of the indicated angle.

Lynna [10]

Answer:

${ \rm{100 + (13x + 2) + (18x + 2) + 70 = 360}} \\ \\ { \rm{31x + 174 = 360}} \\ \\ { \rm{31x = 186}} \\ \\ { \rm{x = 6 }}$

• Angle C

${ \rm{m \angle C = (13x + 2)}} \\ \\ { \rm{m \angle C = (13 \times 6) + 2 }} \\ \\ { \rm{m \angle C =80 \degree }}$
