Question 211322
please help me solve I do not understand
1.3(7x+4) > 1.8-(x+5)
;
multiply both sides by 10 to get rid of those annoying decimals, results:
13(7x + 4) > 18 - 10(x + 5);
:
Multiply inside the brackets
91x + 52 > 18 - 10x - 50
91x + 52 > -10x - 32
:
91x + 10x > -32 - 52
101x > -84
x > {{{(-84)/101}}}
x > -.83168
:
Check to see if true when x = -.8 which is greater than -.83168
1.3(7(-.8)+4) > 1.8-(-.8+5)
1.2(1.6) > 1.8-(4.2)
-.12 > -2.4
