The solution of - t/18 ≥ 10 is t ≤ -180 true or false?

True

Step-by-step explanation:

given - ≥ 10 (multiply both sides by 18 )

- t ≥ 180 ( multiply both sides by - 1)

Remembering to reverse the symbol as a consequence of multiplying by a negative quantity, hence

t ≤ - 180

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
