Answer:

a ≥ 3

Step-by-step explanation:

-4a + 5 ≤ -7

First, subtract 5 from both sides of the equation to isolate -4a:

-4a + 5 - 5 ≤ -7 - 5

-4a ≤ -12

Now, both numbers are negative and divisible by 4 so divide both sides by -4:

$\frac{-4a}{-4a} \geq \frac{-12}{-4}$

a ≥ 3

Hope this helps!

2p/9+5p/18-5/6=2/3+p/12+1/6

Murljashka [212]

$\frac{2p}{9} + \frac{5p}{18} - \frac{5}{6} = \frac{2}{3} + \frac{p}{12} + \frac{1}{6}$
$\frac{4p}{18} + \frac{5p}{18} - \frac{5}{6} = \frac{2}{3} + \frac{p}{12} + \frac{1}{6}$
$\frac{9p}{18} - \frac{5}{6} = \frac{4}{6} + \frac{1}{6} + \frac{p}{12}$
$\frac{p}{2} - \frac{5}{6} = \frac{5}{6} + \frac{p}{12}$
$\frac{p}{2} - \frac{5}{6} + \frac{5}{6} = \frac{5}{6} + \frac{5}{6} + \frac{p}{12}$
$\frac{6p}{12} = 1\frac{2}{3} + \frac{p}{12}$
$\frac{6p}{12} - \frac{p}{12} = 1\frac{2}{3} + \frac{p}{12} - \frac{p}{12}$
$\frac{12}{5} * \frac{5p}{12} = 1\frac{2}{3} * \frac{12}{5}$
$p = 4$
