xsquared + 8x + 12
Step-by-step explanation:
Answer:
45 girls
Step-by-step explanation:
- Remark
- There are only 2 choices for gender. So if the class is 60% girls, the there must be 100 - 60 = 40% for the boys.
- But we are told that the boys are 30 in number.
- Let x = the total number of students.
Solution
- 40/100 * x = 30 Change the % to a decimal
- 0.4 x = 30 Divide both sides by 0.4
- 0.4 x / 0.4 = 30 / 0.4 Do the division
- x = 30/0.4
- x = 75 students in total
Formula
Total of Boys and Girls = Number of boys + number of girls.
Givens
- Total = 75
- Number of boys = 30
Solution II
- 75 = x + 30 Subtract 30 from each side
- 75 - 30 = x +30 - 30
- 45 = x
- There are 45 girls in the class.
Answer:
x and p equal 92 and y equals 88
Answer:
same side alternate interior angles sum up to 180°.
![x + 72 + 3x = 180 \\ 4x + 72 = 180 \\ 4x = 108 \\ x = 27](https://tex.z-dn.net/?f=x%20%2B%2072%20%2B%203x%20%3D%20180%20%5C%5C%204x%20%2B%2072%20%3D%20180%20%5C%5C%204x%20%3D%20108%20%5C%5C%20x%20%3D%2027)
You would at the distances together, since 120 is above sea level and 39 is below. To find the whole vertical distance (the distance they are apart), just add the values (numbers) together.
![120+39=159](https://tex.z-dn.net/?f=120%2B39%3D159)
![159=the-distance](https://tex.z-dn.net/?f=159%3Dthe-distance)
I hope this helps!
