<u>Answer:</u>
- The solution to the equation is 4.
<u>Step-by-step explanation:</u>
<u>Work:</u>
- 6x - 3 = 21
- => 6x = 21 + 3
- => 6x = 24
- => x = 4
Hence, <u>the solution to the equation is 4.</u>
Hoped this helped.
The answer is a) equilateral triangle. If you want to inscribe a hexagon inside a circle, the tools or constructions that should be used is 6 equilateral triangles. If you draw a hexagon inscribed in a circle and draw radii to the corners of the hexagon, you will create triangles, six of them.<span>

Try this solution:
1. if 1st number is 'x', the 2d number is 'y', then it is possible to make up the system of two equation according to the condition:
2. one number is 11, another number is 10.
You would subtract 8 from both sides making it Z is greater than 4
Answer:
b. Kathy
Step-by-step explanation:
We compare each of their score by how far away from the mean when in term of the standard deviation. Using the following formula
For John he is (85 - 75)/5 = 2.
For Kathy she is (80 - 50)/10 = 3.
Since Kathy is 3 standard deviation better than her class' average, while John is only 2's. We conclude that Kathy did better.
