-5x+7+2x-13<9 Please Explain
olganol [36]
Ok the answer is -5 less than 9 which is true lol


Anyways here’s how I got the answer

-5+7+2x-13 less than 9

Combine like terms in this case it’s -5 and 2, and the other is 7 and -13

-5+2= -3
7-13= -6

Ok now that that’s done here’s the next step

-3x-6 less than 9 solve it


-3x-6 < 9
+6< +6

-3x < 15



Now from there you divide then so
-3x/3 cancels out, and 15/-3 = -5
X=-5

And so -5<9 :) hope this helped!! I will also include a picture of my work (please exult messiness lol)

Sonya and Lucas walk from school to the library they walk 5 blocks south and 4 blocks west to get to the library if the school i
Lelu [443]

We are given coordinates of the school located at a point (9,-1).

Library is located 5 blocks south and 4 blocks west .

According to coordinate axes, south is downward and west is on left side.

So, we need to move 5 units down of 9.

<em>5 units down of 9 would be 9-5 = 4.</em>

And then <em>4 blocks west that mean -1 -4 = -5.</em>

<h3>Therefore, coordinate of the library is located at the point (4,-5).</h3>
