Answer 1

| r + 3 | > 7

r + 3 > 7       r + 3 < -7
r > 7 - 3        r < -7 - 3
r > 4             r < -10

so, r > 4 and r < -10
==========================
what percent of 60 is 12
percent formula : is/of = %/100
percent = x
is = 12
of = 60
now sub
12/60 = x/100
cross multiply
60x = 12 * 100
60x = 1200
x = 1200/60
x = 20%

Answer 2

Hey there, 

Lets solve this equation together , 

Break down the problem into these 2 equations 

$r+3\ \textgreater \ 7$

$-(r+3)\ \textgreater \ 7$ 

Solve the 1st equation: r+3>7

--------------Subtract 3 from both sides

$r\ \textgreater \ 7-3$ 

-------------- Simplify 7−3 to 4 

$r\ \textgreater \ 4$ 

Solve the 2nd equation: −(r+3)≥7 

----Simplify brackets

$-r-3\ \textgreater \ 7$ 

---- Add 3 to both sides 

$-r\ \textgreater \ 7+3$ 

 ----- Simplify 7+3 to 10 

$-r\ \textgreater \ 10$ 

---- Multiply both sides by −1 

$r\ \textless \ -10$  

Collect all solutions 
$r\ \textgreater \ 4$ 

$r\ \textless \ -10$
