Thus , the answer is approximately 33 % . Determine the decrease in temperature by subtracting 50 from 75. The temperature decrease is equal to 25 degrees . To solve for the percent decrease , divide the decrease in temperature by the initial temperature and multiply by 100 % . This is shown below , ( 25/75 ) x 100 % = 33.33 %
Answer:
(3x+5)(3x−5)
Step-by-step explanation:
4/11 = 0.36 (repeat: 36)
5/11 = 0.45 (repeat: 45)
6/11 = 0.54 (repeat: 54)
7/11 = 0.63 (repeat: 63)
She would have 20 dollars left over. take the amount of money she has then add up all of the cost of the stuff she will buy then subtract.
2/3x - 1/2y = 3 |multiply both sides by 6
4x - 3y = 18
1/2x + y = 5 |multiply both sides by 2
x + 2y = 10
Answer: B) 4x - 3y = 18 and x + 2y = 10
