Answer:
x = -7/5 and x = 9/8
Step-by-step explanation:
To solve this equation, set both parts of the "expression" equal to 0.
5x + 7 = 0
Subtract 7 from both sides.
5x = -7
Divide both sides by 5.
x = -7/5
8x - 9 = 0
Add 9 to both sides.
8x = 9
Divide both sides by 8.
x = 9/8
Knowing that one mile is 5,280 feet and an hour is 60 minutes:
10 x 5280 = 52800
60 x 1 = 60
52800 / 60 = <u><em>880 feet per minute</em></u>
Hope this helps!
X/5 - 3 < 5....add 3 to both sides
x/5 < 5 + 3
x/5 < 8....multiply both sides by 5, eliminating the 5 on the left side
x < 8 * 5
x < 40 ...... ur solution
* and just so u know, x/5 is the same as (1/5)x....in case u wanted to solve it a little different........1/5x < 8...u would divide both sides by 1/5.....x < 8 / (1/5).....x < 8 * 5/1......x < 40....u will still get the same answer
Answer: All these numbers are the cube of consecutive numbers ,the cube of 1 is 1, the cube of 2 is 8 ,3 is 27 ,4 is 64 and so the next number which is 5 , it's cube will be 125 and so the series will be 1, 8, 27, 64, 125 ,216 and so on…!
