Marking brainliest to whoever can help and explain

Mathematics
1 answer:
lyudmila [28]3 years ago
3 0

Answer: I hope I got it right. You can mark brainliest if you want. I don't really care.

Step-by-step explanation:

Well, it seems that for every week, Pragitha swims x + 2 laps. So if she swims x + 2 laps twice, she will get 2x + 4. So x is equal to 4. You add that four and you get three x. So for one week, she swims x + 2 laps and for the second lap, she swims 2x + 4. Which according to the table, is equal to 3x. So for 3 weeks, she clearly swims less, because maybe she's tired or something. So it's 2x+1. And for week 4, it's week one and week 2 combined.

The expression on the other hand is

10x + 9

Answer:

the angle is 245°

Step-by-step explanation:

that is a pentagon, (a shape with 5 sides)

we know 4 of the angles in the pentagon

the sum of those 4 angles is

58°+100°+112°+25°=295°

to find a shapes total amount of °, the equation is (n-2)x180°

(5-2)x180°

=540°

540°-295°=245°

x=245°

Question 11: Please help, Which statement(s) should be used in proving that vertical angles 1 and 3 are congruent?
mihalych1998 [28]

Answer:

B.  m < 1 + m < 2 = 180;  m < 2 + m < 3 = 180.

Step-by-step explanation:

m < 1 + m < 2 = 180  so  m < 1 = 180 - m < 2

m < 2 + m < 3 = 180  so   m < 3 = 180 - m^2.

So by the transitive property of equality  m < 1 = m < 3.

Which equation represents a line that is parallel to the line 2y-10=x?
koban [17]

We can use some simple algebra and rewrite the equation in slope-intercept form (y = mx + b), a form of a line that is the most familiar to people.

We have y = (1/2)x + 5

Because we have second line parallel to the first line, the equation of second line is y = (1/2)x + b', where b' couul be any real number ( for instance b' = 15); then y = (1/2)x + 15;

Finally, 2y -30 = x is the equation of second line.
