I'm not sure how to solve the first one, but I'll try to simplify sqrt3-1/sqrt3+1. I simplified it and I got 2-sqrt3. Does that help?
For question 2, I got -0.251.
Answer:
1) [tex]\frac{\sqrt{3}-1 }{\sqrt{3}+1}=\frac{(\sqrt{3}-1)^{2} }{(\sqrt{3}+1)(\sqrt{3}-1) }=\frac{4-2\sqrt{3} }{3-1}=\frac{4-2\sqrt{3} }{2}=2-\sqrt{3}[/tex]
but [tex]\frac{\sqrt{3}-1 }{\sqrt{3}+1 }=a+b\sqrt{3}[/tex]
=> a = 2
b = -1
2) [tex]\frac{\sqrt{10}-\sqrt{15} }{2\sqrt{2} }=\frac{\sqrt{20}-\sqrt{30} }{4}=\frac{2\sqrt{5}-\sqrt{30} }{4}=-0.251[/tex]

HELP ASAP PLEASE! I need to write an equation in point-slope form of the line that passes through the points below
Step-by-step explanation:
step 1. pick one of the points: (-2, 5)
step 2. calculate the slope of the points (-2, 5) and (1, -1). m = (-1 - 5)/(1 - (-2)) = -6/3 = -2
step 3. plug them in: y - y1 = m(x - x1) = y - 5 = -2(x - (-2)).
Sixty percent, or 12, of the students in Alex's class are going to the movies. 2/3, or 14, of the students in Mary's class are going to the movies. Which class has more students? Justify your answer using equations.
Answer:
Mary's class.
Step-by-step explanation:
One way to do this is to figure out how many students are in Alex's class and how many students are in Mary's class.
60% of Alex's class is 12 students
[tex]\frac{12*100}{60}[/tex] = [tex]\frac{1200}{60}[/tex]= 20 students
[tex]\frac{2}{3}[/tex] or 66.66% (repeating) of Mary's class is 14 students
[tex]\frac{14*100}{66.66}[/tex] = [tex]\frac{1400}{66.66}[/tex] = 21 students
(^^66.66 repeating)
Mary's class has more students than Alex's class.

Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies. For every 555 movies on the list, there are 222 \_\_\_\_____\_, \_, \_, \_ movies.
Answer: Comedy
Step-by-step explanation:
Find out the percentages of each of the movies. First find the total quantity.
= 888 + 666 + 555 + 111
= 2,220 movies
Comedy = 888/2,220 * 100% = 40%
Action = 666 / 2,220 * 100% = 30%
Fantasy = 555/2,220 * 100% = 25%
Drama = 111/ 2,220 * 100% = 5%
222 movies out of 555 is:
= 222 / 555 * 100%
= 40%
222 movies out of 555 movies will therefore be comedy.
Answer:
222/555 are comedy

The enrollment at a university increased from 1,000 students to 6,000 students over a 6-year period. What was the percent increase in enrollment over that time period?
Answer: 500%
