Subtract 985 from 177 since Anna has 177 more songs than Ryelin. Then divide that answer by 2 which gives each one an equal amount then add 177 to one of the answers to get how many each girl has.
So Ryelin has 404 songs downloaded and Anna has 581 songs downloaded.
21 and 22 because 21+22=43
Pythagoras theorem ! (a²+b²=c²)
Q1) AC = √4.8²+3.6²
= √36
= 6cm
Q2) AB= √17.55² - 6.75²
= √262.44
= 16.2cm
Q3) BC= √14² - 6²
= √160
= 12.64911
= 12.6 cm (to 3sf)
I believe the GCF would be 2n
The given equation of the line is in slope - intercept form where the slope is 3 and the y - intercept is 2. The line perpendicular to the given has a slope which is equal to its negative reciprocal. Thus, the slope of a line perpendicular to y = 3x + 2 is -1/3. The answer is letter D. -1/3
