(3 +x) - 100
is the expression
Answer:
39 students
Step-by-step explanation:
In order to solve this you need to first set up a proportion with x equaling the number of students who voted for the athlete, 65/100 = x/60. 65/100 represents 65% and it is equal to a certain number of students out of 60. To solve for x you need to cross multiply so you would have 100x=65(60), simplified this would be 100x=3900, then you divide both sides by 100 to get x over 39. So, 39 students voted for the athlete.
Answer:
x = -48
Step-by-step explanation:
-4(7.5x - 8) = -5(6.3x + 8)
-30x + 32 = -31.5x - 40
-30x + 31.5x = -40 - 32
1.5x = -72
x = -72/(1.5)
x = -48
You can split the figure into a top and bottom box.
Top box has the measurements of 3 by 18 by 20. When you multiply those together you get the volume of that box- 1080.
Bottom box has the measurements of 15 by 8 by 8. Multiplied together for the volume is 960.
Adding the top and bottom box together (1080+960) you get a total of 2040 yards cubed.
Answer:
Step-by-step explanation:
Yes.
Since the universal set of rational numbers range from negative infinity of rational numbers to positive infinity of national numbers, then -3 is part of the of rational numbers set.
