Answer:
800 in scientific notation
8 * 10²
Keeping in mind that complex solutions never come all by their lonesome, they always come with their sister
thus, "i" is not there all by herself, her sister is there too, namely the conjugate
so
i = 0+i and thus its conjugate sister will be 0-i
thus
Answer: $20
$48/24 = $2 for each candy bar
10 candy bars * $2 = $20
The answer is -83.7418
Rounded to: -83.74
Answer:
Step-by-step explanation:
The equations that she wrote are
6x+8y=133
2x=y
The following statements about the system are true
1.Since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133
5. The second equation is correct because there are more 6 inch pies and 2 times a number is always more.
The following statements are wrong because,
2. Because there was no relationship between the number of pipes sold and the size of each pipe.
3. x=2y shows that there are more 8 inches pipes
4. 6 and 8 are just size descriptions. It is only the cost of each size of pipe that related to the total cost
