Answer:
6x - 5 = 67
6x = 72
x = 12
Step-by-step explanation:
setting the equation and variable x to the number
6 times the number and its difference to five is 67
plus five on both sides
divide both sides by 6
answer is 12
Answer:
776644 rounds to 777000
Step-by-step explanation:
hundred thousand ten thousand thousand hundred tens ones
7 7 6 6 4 4
We are rounding to the nearest thousand so we are rounding the first 6. We need to look at the next 6 (the one in the hundreds place) 6>=5 so we will round the 6 in the thousands place up to 7
776644 rounds to 777000
The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.
For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.
There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.
ANSWER: 10
