Answer:

{x | x < 3}

Step-by-step explanation:

Just easily solve for x.

3x < 9

x < 9 ÷ 3

x < 3

{x | x < 3} means that any number for x is less than 3.

Answer:

the simplest form of the given expression is $-1\frac{4}{35}$

Step-by-step explanation:

Given;

$2 \times \frac{1}{7} - 1\frac{2}{5}$

The above expression can be simplified as follows;

$2 \times \frac{1}{7} - 1\frac{2}{5} \\\\=\frac{2}{7} - \frac{7}{5} \\\\= l.c.m \ of \ 7 \ and \ 5 \ is \ 35\\\\= \frac{5(2) - 7(7)}{35} \\\\= \frac{10 - 49}{35} \\\\= -\frac{39}{35} \\\\= - 1\frac{4}{35}$

Therefore, the simplest form of the given expression is $-1\frac{4}{35}$

Solve for x round to the nearest degree if necessary

natulia [17]

Answer: 35.9 degrees

Step-by-step explanation:

Since cosine(x) is adjacent/hypotenuse, cosine(x) = 47/58.

Therefore we can take the arc cosine of 47/58, and we get x is about 35.9
