jenny read 9 books in 21 weeks. The diagram shown can be used to track her progress. If jenny read at the same rate each​ week, how many books had jenny read in 7 ​weeks? In 14 ​weeks? AS A FRAtIoN PLZ!! :)

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form. −three fourthsx + y = 10 3x − 4y = −40 y = three fourthsx + 12 y = three fourthsx + 10
