Since we have the 2.1 next to the parenthesis, we need to first distribute.
2.1 * x & 2.1 * 5
2.1x + 10.5
Then we take that and add the equals seven to the problem to move onto the next step.
2.1x + 10.5 = 7
We must get the 2.1x alone, therefore subtracting the 10.5 as it will also be subtracted on the other side as well.
2.1x + 10.5 = 7
- 10.5 -10.5
2.1x = -3.5
To get the x alone, we must divide both sides by 2.1, therefore removing the 2.1 from the x.
2.1x = -3.5
/2.1 /2.1
x = 1.66666666667
Hope this helped!

Answer: 45 degrees</h3>
Explanation:
There are n = 8 sides in a regular octagon. The smallest angle of rotational symmetry is 360/n = 360/8 = 45 degrees. Rotating this amount will not change the regular octagon. The before and after will look identical.
Answer:
26
Step-by-step explanation:
First calculate the square roots of 19 and 77.
≈4.36
≈8.77
The integers between this will be the lowest rounded up and the highest rounded down.
Integers Included:
5,6,7,8.
I think u would do 20/4. Which is five. Then 5*2=10. Add the ten to the thirty. Final answer is 40
