$-\frac{8}{3} m = 6$

$-8m = 6(3)$

$-8m = 18$

$m = \frac{18}{-8}$

$m = -\frac{9}{4}$

$m = -2\frac{1}{4}$

$0.12x = 1$

$x = 1/0.12$

$x =$ $\frac{25}{3}$

$x = 8\frac{1}{3}$

Please help me (It's for a really important grade)

Sholpan [36]

Answer:

4/5

Step-by-step explanation:

Sin = Opposite / Hypotenuse

Note that hypotenuse = longest side

We want to find sinФ

The opposite side length of angle "Ф" has a length of 8 and the longest side or hypotenuse has a length of 10

So sinФ would equal 8/10 which can be simplified to 4/5

F(n) = 93 + 4(n − 1)

Lunna [17]

Answer:

$f(1) = 93$ , $f(n) = f(n-1) +4$

Step-by-step explanation:

The value of f(1) is:

$f(1) = 93 +4\cdot (1-1)$

$f(1) = 93$

The values for n and n-1, are respectively:

$f(n-1) = 93 + 4\cdot (n-2)$

$f(n) = 93 + 4\cdot (n-1)$

After some algebraic manipulation, the following expression is obtained:

$f(n) = 93 + 4\cdot (n-2) + 4$

$f(n) = f(n-1) +4$

Answer:

6x − y = 1 -------(1)

4x − 3y = −11 ------(2)

(1)×3

18x - 3y =3 ------(3)

4x − 3y = −11 ------(2)

(3)+(2)

18x - 3y + ( 4x - 3y) = 3+(-11)

d. 4x − 3(−6x − 1) = −11 is the answer.
