Answer:
<u>1/7=3/21</u>
<u>7/1=21/3</u>
the other fractions are not correct/valid therefore the fractions above are the correct answers
Step-by-step explanation:
Let me know if you need any other help:)
15. -(-7y + 12) = 7y - 12
16. 1/a = 16/18
cross multiply
16a = 18
a = 18/16 = 9/8
17. 8x - 12 = 4x + 24
8x - 4x = 24 + 12
4x = 36
x = 36/4
x = 9
18. -6b > 42 4b > -4
b < 42/-6 b > -4/4
b < - 7 b > -1
so b < -7 and b > -1
19. 6 more then the product of 8 and n
6 + 8n
20. 45 = 3b + 69
45 - 69 = 3b
-24 = 3b
-24/3 = b
-8 = b
Answer:
The mean will change, the median will stay the same.
Step-by-step explanation:
The mean will increase because that is the average and a gain of 1000 kg will increase that average.
The median will not change. The median is the middle point. That was the highest point before and increasing it will not change that it was the highest point.
Your answer will be 1,000.3125
hope i helped!! :)
Multiply 3x and -2 by 3 and add 5 to right side of equal sign to get y = -1
