SOLUTION:
Step 1:
In this question, we are meant to:
Translate the following word phrases to an algebraic expression and simplify:
“8 times the difference of 6 times a number and 3”
Step 2:
Assuming the unknown number be y, we have that:
CONCLUSION:
The final answer is:
<span>a) We know that the correct answer will be the square root of 256 since the competition area is a square with an area of 256 meters. And since 10^2 = 100 which is less than 256, the answer has to be greater than 10. And since 20^2 = 400 which is greater than 256, the answer also has to be less than 20. Therefore the answer has to be between 10 and 20.
b) The last digit has to be either a 4 or a 6. The units digit is the only digit that will contribute to the units digit of the square. And 0^2 = 0, 1^2 = 1, 2^2 = 4, 3^2 = 9, 4^2 = 16, 5^2 = 25, 6^2 = 36, 7^2 = 49, 8^2 = 64, 9^2 = 81. Of the 10 possible digits, only the values 4 and 6 have a square that has an units digit of 6.
c) The square root of 256 based up (a) and (b) above has to be either 14, or 16. So the dimensions are either 14x14 meters or 16x16 meters.</span>
2/3 divide by 5 is 2/15
Remember keep change flip
2/3 times 1/5 is 2/15
Hope this helps!
Here is the equation: (gas=g)
8.5g= 23.94
All you need to do is the inverse of multiplication on the other side. (division)
23.94/8.5= 2.81647.....
g= 2.82 (rounded to the hundredths place)
I hope this helps!

Independent variable on x-axis (value you can choose)
dependent variable on y-axis (corresponding value for the value you have chosen)
You can the hours and the distance traveled is a function of those hours.
also, I'd go in increments of 5. More accurate than increments of 15. The answer is D! <span><span>
Hope this helps!</span></span>
