Answer:14y
Step-by-step explanation: You just multiply 7 by 2y
Ote: (21/n)n = 21)
Numbers 21/n and n
Question States***
(21/n) = 4n - 5
21 = 4n^2 - 5n
4n^2 - 5n - 21 = 0
(4n + 7) (n - 3) "Find the integers" n = -7/4 will Not work
n = 3 and the other number is 7 21%2F3
Answer:
B
Step-by-step explanation:
The equation would be 12 + 30 = x, because the amount of miles James ran all together would be the sum (what the numbers add up to).
A = 1/2 bh can be written as
A = bh/2.
2A = (bh/2)(2)
2A = bh
Divide both sides by h to find b.
2A/h = b
Done.
No, 3/7 and 7/3 are completely different values. If they represented the same length 3/7 would equal 7/3, which it doesn't. 3/7 = about 0.43 and 7/3 = about 2.33. 0.43 does not equal 2.33.
