A-4/5 = 12 what is a and show the work

topjm [15]

Solving $a-\frac{4}{5}=12$ we get $a=\frac{64}{5}$

Step-by-step explanation:

We need to find the value of a. We are given:

$a-\frac{4}{5}=12$

Solving:

$a-\frac{4}{5}=12\\Add\,\,\frac{4}{5}\,\,on\,\,both\,\,sides:\\a-\frac{4}{5}+\frac{4}{5}=12+\frac{4}{5}\\a=12+\frac{4}{5}\\Taking\,\,LCM:\\a=\frac{12*5+4}{5}\\a=\frac{60+4}{5}\\a=\frac{64}{5}$

So, Solving $a-\frac{4}{5}=12$ we get $a=\frac{64}{5}$

Solve the following inequality: –1 6(–1 – 3x) > –39 – 2x

jeka57 [31]

If you would like to solve the inequality <span>–1 + 6 * (–1 – 3x) > –39 – 2x, you can do this using the following steps:

</span>–1 + 6 * (–1 – 3x) > –39 – 2x
-1 - 6 - 18x > -39 - 2x
-7 + 39 > -2x + 18x
32 > 16x
32/16 > x
x < 2

The correct result would be x < 2.

sdas [7]

Step-by-step explanation:

x- red candy

y- blue candy

x + y = 11

1.29x + .79y = 11.19

129x +79y = 1119

-129x -129y = -1419

-50y = -300
