Answer:
Step-by-step explanation:
35% means 35 per hundred. 35/100. simplify and write as 7/20.
0.64 means its 2 zeros left of regular number. 64/100.
82% means 82 per hundred. 82/100. move decimal 2 spaces to left (division is left, multiplication is right). 0.82.
4/5. try to make denominator 100. multiply both numerator and denominator by 20. 80/100. move decimal 2 spaces to the left. 0.8.
14/50. try to make denominator 100. multiply both numerator and denominator by 2. 28/100. 28%
0.19 can be written as 19/100. 19%
Answer:
<h2>84, 42</h2>
Step-by-step explanation:
Answer:
(x, y) = (5, 1)
Step-by-step explanation:
To <em>eliminate</em> x, you can double the second equation and subtract the first.
... 2(x +4y) -(2x -3y) = 2(9) -(7)
...11y = 11 . . . . . simplify
... y = 1 . . . . . . divide by 11
Using the second equation to find x, we have ...
... x + 4·1 = 9
... x = 5 . . . . . subtract 4
_____
<u>Check</u>
2·5 -3·1 = 10 -3 = 7 . . . . agrees with the first equation
(Since we used the second equation to find x, we know it will check.)
The standard form of thr number is 11.651
