1. use an inequality to solve the following problem. show all work. rita plans to spend at most $115.00 on a skirt and two blouses. she bought the two blouses for $38.95 each. how much can she spend on the skirt?

2.solve the following and show all work.

-5 - 2(3x - 4) = 21

3.five times a number increased by 8 is seven less than 6 times the number. find the number.

1.  2(38.95) + x < = 115.00
   77.90 + x
subtract 77.90 from both sides
x < = $ 37.10 is the most she can spend on a skirt

2.  -5 -2(3x - 4) = 21
add 5 to both sides
-2(3x - 4) = 26
distribute the -2
-6x + 8 = 26
subtract 8 from both sides
-6x = 18
divide both sides by -6
x = -3

3.  5x + 8 = 6x - 7
subtract 6x from both sides
-x + 8 = -7
subtract 8 form both sides
-x = -15
divide both sides by -1
x = 15

This is what i found “answer: a rigid transformation preserves both the side lengths and the angle measures of a polygon. step-by-step explanation: rigid transformations are the transformations which does not affect the size and the shape of figure .” i hope this you for what your looking for. can you plz mark me brainliest?

B.the point lies directly on the regression
