1+4=5<br> 2+5=7<br> 3+6=21<br> 8+11=
Karolina [17]
This is a common math problem. There are two ways to answer this question but both will give you the same answer. There is a misconception that this can also equal 40. If someone posts that the answer is 40, please let me know and I will explain why that is not actually the answer.

1+4=5 2+5=7
3+6=21
8+11=

These equations are actually:

1*(4+1)=52*(5+1)=7
3*(6+1)=21
8*(11+1)=96

Therefore:
8+11 = 96

What are the measures of &lt; 1 and &lt; 2. Show your work or explain your answer.
VashaNatasha [74]

Answer:

m<1 = 105°

m<2 = 75°

Step-by-step explanation:

Since lines c and d are parallel to each other, therefore:

m<2 = 75° (corresponding angles are congruent)

m<1 + m<2 = 180° (linear angle pair)

Substitute

m<1 + 75° = 180°

Subtract 75 from both sides

m<1 = 180° - 75°

m<1 = 105°

What is 68,642 rounded to the nearest thousand?
Sergeeva-Olga [200]
68,642 rounded to the nearest thousand is 69,000.

It's because 68,642 is closer to 69,000 than to 68,000.

I hope it will help you and give a clue for rounding numbers in the future ;)
