Answer:

Only one solution.

Step-by-step explanation:

1) Collect like terms.

$2((6x-3x)+9)-5x+21$

2) Simplify $(6x-3x)+9$ to $3x+9$ .

$2(3x+9)-5x+21$

3) Expand by distributing terms.

$6x+18-5x+21$

4) Collect like terms.

$(6x-5x) +(18+21)$

5) Simplify.

$x+39$

Therefore, the answer is x + 39 and there is only one solution possible.

This will take me a long time, but... $x+ \frac{3}{4} = x- \frac{1}{5} =x+ \frac{3}{4} -x = x- \frac{1}{5} -x = \frac{3}{4} =\frac{1}{5} =\frac{3}{4} - \frac{3}{4} =\frac{1}{5} - \frac{3}{4}
$ $=\frac{-19}{20}$

Nonamiya [84]

Answer:

ok, so pretty much you can set up an equation for this. You can use fractions to find this out.

Step-by-step explanation:

<h2> $\frac{5}{400} =\frac{25}{x}$ </h2><h2 /><h2>what you do is multiply 400*25 and then divide by 5. It should be 2000</h2>

Answer:

11/60

Step-by-step explanation:

It is convenient to use the relationship between sine, cosine, and tangent.

tan(x) = sin(x)/cos(x) = (11/61)/(60/61)

tan(x) = 11/60
