m * 26   =   2995  + 11m

15m = 2995

m = ~~ 200 minutes

Supplementary means the add to 180 degrees

8x+6      +    7x+ 24 =  180

x = 10                         B = 7x + 24 = 7(10) + 24 = 94 degrees

In 3 minutes the train travels the lenth of the tunnel + 400 m   ( the length of the train)

60 km/hr = 1 km/ min

1 km/min * 3 min = 3 km         so the tunnel  is 3 km - 400 m =   2.6 km long

You didn't list the choices ..... 

Sub into the equation

6 = 15 sin (2pi 120 t)

6/15 = sin(240 pi t)

.4115 R = 240 pi t

.4115 R = pi t

t = .131    sec

P ( first card  is not black)  =   1/2

P ( second card is not black) =  25 / 51

Total  probability  =   (1/2) (25/51)     = 25 / 102

1/3 = 3/9

He sold 1/9 of the fruits.

Apple - Flavoured sweets = A

Lemon - Flavoured sweets = L

     
    (A - 75) + L    =   6 (A - 75)             ,     ( L - 60) + A = 3A

     A - 75 + L    =   6A  - 450                       L - 60 + A = 3A 

     SA - L     =   375 ---- 1                            2A - L = -60 ---- 2

 Via Elimination  :  1 - 2  :  3A  =  435

                                            A  =  435/3

                                                =  145

                                            L  =  SA - 375

                                                =  725 - 375

                                                =  350

Total no-of sweets = 145 + 390

                              =  495

AM-GM can likely help you here lol

the equation would go $a + \dfrac{c^3}{(a - b)b} \geq 3 \sqrt[3]{ \dfrac{(a - b)bc^3}{(a - b)b}} = 3c.$

this'd imply that, $4a + 3b + \frac{c^3}{(a - b)b} \geq 3a + 3b + 3c$

the rhs is 3(a + b + c), or 12 - thus, 12 is the local minimum.

Answer: (0.69, 0.87), the last one.

Explanation: I just took the test! Good luck, everyone! 😁

Brilliant!

\(8-2\frac{5}{9}=8-(2+\frac{5}{9})=6-\frac{5}{9}=5\frac{4}{9}\)

As follows:

T = 4J/9

2J - 42 = T

Solving, J = 27 and T = 12

27 - 21 is 6. and 12 - 6 = 6. The answer is 6.

I found these articles that helped me understand your question. I hope they will help you, too.

Assuming that you wrote \(8- 2(\frac{5}{9})\), the answer is \(6(\frac{8}{9})\).

Hope that helped!

Lets use the variables A and L. 

There is, A - 75 + L = 6(A - 75).

Also, A - 75 + L - 60 = 3(A - 75). 

solving the equations, I get A = 95, and L = 100.Therefore, the total is 195.

Ooh okk thank you!
