Answer: (u+7) x -3

I like to use substitution, for example u=2

(2+7) x -3 = -27

-3(2+7) = -27

At the beginning of every year, Molly deposits $200 in a savings account that offers an interest rate of 20%, compounded annuall

It is I=PRT. So you would first make the "20%" into a decimal. After you turned the 20% into a decimal, you would multiply the the rest of the numbers (200 and 3) with the decimal you got. It should look like this: 200× 0.20 × 3= answer

Olin [163]

-5 = 0.2k
divide both sides by 0.2 to isolate k
-25 = k

might be wrong tho lol

Find a. Round to the nearest tenth:

Ulleksa [173]

Step-by-step explanation:

In the following triangle, a= ? , b= 2cm.

m<B= 105° , m<C = 15° ,m< A =?

Now, we know that sum of the interior angles of the triangle = 180°

m<B+m<C +m< A =180°

105°+15°+m< A=180°

m< A= 180- 120° = 60°

$\frac{ \sin( A) }{a} = \frac{ \sin(B) }{b}$

$\frac{ \sin(60) }{a} = \frac{ \sin(105) }{2}$

$a = \frac{ \sin(60) }{ \sin(105) } \times 2$

$a = 1.79$

$a = 1.8$
