Answer:
The index of a number says how many times to use the number in a multiplication. It is written as a small number to the right and above the base number. In this example: 82 = 8 × 8 = 64. The plural of index is indices. (Other names for index are exponent or power.)
Step-by-step explanation:
Answer: 264.0625
8•2 is 16 + 1/4 and then 16 1/4 squared
<span>7/8 = 7 * 1/8 and 1/8 = 1 : 8 = 0.125. After that: 7 * 0.125 = 0.875. Finally, 0.875 > 0.78. We can do it also by transforming 0.78 to fraction: 0.78 = 78/100 = 39/50 and then multiplying the numerator and the denominator by 4: 39/50 = 156 / 200 . Then we will also multiply 7/8 * 25/25 = 175/ 200. Obviously: 175/200 > 156/200. Answer: 7/8 is bigger than 0.78. </span>
If x=2, the equation would be 6 (2) + 3y = 15.
This simplifies to 12 +3y = 15. Subtract 12 from both sides and you get 3y = 3. Divide both sides by 3 and you get y = 1.
So if x = 2, y =1
If x = 5, the equation becomes 6 (5) + 3y = 15.
This simplifies to 30 + 3y = 15. Subtract 30 from both sides and you get 3y = -15. Divide both sides by 3 and you get y = -5.
So if x =5, y = -5.
I hope this helps!
