I am very weak in this help me please. There are 1800 gym members in total.3/4 are aged 25 to59 years, 1/5 are over 60 years and remainder are under 25 years. How many members are under 25 years?
Answers
Answer 1
Answer:
Steps to solve:
1. 3/4+1/5 Change both denominator to the same- 4*5=20 So far its: ?/20 + ?/20
2. For the first fraction (3/4) we do 3*5=15 Because when we found the denominators we multiplied each denominator by each other. For the second one we do pretty much the same. We do 1*4=4.
3. The final equation is 15/20 + 4/20. Now add both numerators, which is 19. You leave the denominator as it is. So the final fraction is 19/20.
4. Next to get a full fraction from 19/20 you need 1/20 to get 20/20=1. On the calculator you type in: 1/20*1800 OR... 1800/20 OR... (18/2)100
So the final answer is 90. 1800/20=90 = 90 members under the age of 25.
Answer 2
Answer:
To solve this, we add , 3/4 + 1/5
To add fractions we different denominators we have to find a common multiple.. 4 * 5 = 20 and 5 * 4 = 20
We multiply everything by 5 (for 3/4), to get 15/20 We multiply everything by 4 (for 1/5), to get 4/20 = 15/20 + 4/20 (add the numerators) = 19/20
If 19/20 people are 25 to 60+, that means 1/20 of people are under 25
If x < 5, then which of the following must be true?-x < -5 -x > -5 -x < 5 -x > 5
Answers
If x > 5, than it stands to reason that -x < 5. Say x is 17. 17 > 5, that is true, but when you add a negative in front of 17, it becomes -17 > 5, which is not true, but -17 < 5 is. The third answer choice is correct.
Answer:
-x<5

What is bigger , 3/5 or 65%
Answers
3/5 is equal to 6/10 6/10 times 10 equals 60/100 so 60% so 65% is bigger than 3/5
1(5/5) is 100% 3/5=100×3/5=60% 60%is less than 65%
One angle in a triangle measures 120°. Which of the following could not be one of the other angle measures?20°
33°
45°
73°
Answers
73 BECAUSE there are 180 degrees in a triangle when all the angles are added together. If one angle is 120 then the other angles must add up to 60 (180-120=60). It can't be 73 because then that means there would be no other angle and there has to be 3 angles in a triangle.
That would be 73 degrees.
Angle 6 is 55 degrees and angle 5 is 125 degrees. Are these angles vertical or adjacent?
Answers
vetical angles are congruent and have the same angle measure 55 is not equal to 125
adjacent angles are next to each other on a stratight line so they add to 180 55+125=180
they are adjacent
