What would the answer be for this equation 7x/20 - 5x/12

polet [3.4K]

Answer:

$\frac{1}{15} x$

Step-by-step explanation:

$\frac{7x}{20} - \frac{5x}{12}$

$\frac{3 \times 7x}{3 \times 20} - \frac{5 \times 5x}{5 \times 12}$

$\frac{21x}{60} - \frac{25x}{60}$

$\frac{21x - 25x}{60} = (21 - 25)x = - 4x$

$\frac{ - 4x}{60} = - \frac{ x}{15}$

$\boxed{\green{= \frac{1}{15} x}}$

How do I do this? I need it in perimeter to 2 decimal places. Thank you!

ad-work [718]

Answer:

The perimeter is 127.1 cm

Step-by-step explanation:

30+25+25=80

(2)(3.14)(15)=94.2

94.2/2=47.1

Divide by two because of the semicircle

80+47.1=127.1

Please help me with this question!!

Bess [88]

Answer:

$x=16 * cos(46)$

Step-by-step explanation:

Well, first let's look at our trig identities. We can set up a cosine function using the given angle:

$cos (46^{o} ) = \frac{x}{16}$ (adjacent/hypotenuse)

Then, multiplying both sides by 16 gives us:

$x=16 * cos(46)$

Hope this helps!
