Answer 1
Answer:
A. The equation that represents the price, e, of the electricity is e + 0.05e + 6.30 = 48 C. The cost of the electricity before taxes or fees is $39.71.
e + 5% of e + 6.30 = 48 e + 0.05e + 6.30 = 48 1.05e = 48 - 6.30 1.05e = 41.70 e = 39.71

example:
7x7x7x7x7x7x7x7x7x7x7x7=84 there are 12 sevens u put the deleted number as the big number (7) and the number of repeated numbers as the smaller sized number which is called the exponent (12)
why do whole numbers raised to an exponent get greater while fractions raised to an exponent get smaller
Answers
Because in fractions you are taking away. For example: if you multiply 1/2 times 1/2, you are taking 1/2 away from that original half, but with whole nombers you are increasing the value. For exapmle: if you multiply 2 times 2, it will give you more.

What's bigger 2/3 or 4/5
Answers
The best thing to do is either to find a common denominator or convert them to decimals. I will find a common denominator. A common denominator of 3 and 5 is 15. You multiply the first fraction by 5 2*5= 10 This then becomes 10/15 You then multiply the second by 3. 4*3= 12 Therefore, this becomes 12/15 As the second of these fractions is larger, this means that 4/5 is larger. The alternative method is to put them into decimals, in which case 2/3= 0.66 and 4/5= 0.8 Hope this helps :)
find the LCD (15) and change the fractions to: 10/15 and 12/15. compare the numerators, 12 is greater, so **4/5** is greatest
