In the equation below, solve for x a+12x=m

ryzh [129]

Answer:

x = $\frac{m-a}{12}$

Step-by-step explanation:

Isolate the term in x by subtracting a from both sides

12x = m - a ← divide both sides by 12

x = $\frac{m-a}{12}$

Over time, the value of the property at 397 West Lake Street increased by 275%. If the initial value of the property was P, whic

larisa86 [58]

Answer: Third option is correct.

Step-by-step explanation:

Since we have given that

Initial value of the property = P

Rate of growth = 275%

So, we need to find the property's current value:

We will use "compound interest ":

$Amount=P(1+\dfrac{r}{100})^t\\\\Amount=P(1+\dfrac{275}{100})^1\\\\A=P(1+2.75)\\\\A=3.75P$

Hence, Third option is correct.

Answer:

41.8 degrees for both angles

Step-by-step explanation:

Because the angle is bisected, it creates two equal, lesser angles. This means that the larger angle must be divided by two.

Precalculus PLEASE HELP ME right answers only check all please

Alex_Xolod [135]

Given :

$cos(x)cos(\frac{\pi }{7}) + sin(x)sin(\frac{\pi }{7})=-\frac{\sqrt{2}}{2}$

We know the identity

$cos(x)cos(y) + sin(x)sin(y)=cos(x-y)$

We use this property to simplify the left hand side

So $cos(x)cos(\frac{\pi }{7}) + sin(x)sin(\frac{\pi }{7})=cos(x - \frac{\pi }{7})$

$cos(x - \frac{\pi }{7}) =-\frac{\sqrt{2}}{2})$

we know ,

when $cos(x) =-\frac{\sqrt{2}}{2})$ then

$x = \frac{3\pi }{4} , \frac{5\pi }{4}$

For $cos(x - \frac{\pi }{7}) =-\frac{\sqrt{2}}{2})$

$x - \frac{\pi }{7}= \frac{3\pi }{4} and x - \frac{\pi }{7}= \frac{5\pi }{4}$

Add $\frac{\pi }{7}$ on both sides

$x= \frac{3\pi }{4} + \frac{\pi }{7} and x= \frac{5\pi }{4} +\frac{\pi }{7}$

Finally we add 2npi for general solution

So options C and D are correct

Simplify (9a2‐18ab + 9b2 -25c2) ÷ (3a–3b+5c) brainly

Pani-rosa [81]

Answer:

3a-3b-5c

Step-by-step explanation:

((3a-3b)²-(5c)²)÷(3a-3b+5c)=((3a-3b-5c)(3a-3b+5c))÷(3a-3b+5c)=3a-3b-5c
