Answer:

10.8

Step-by-step explanation:

By sine rule:

\frac{x}{ \sin 81 \degree}  =  \frac{7}{ \sin 40 \degree}  \\  \\ x = \frac{7 \sin 81 \degree}{ \sin 40 \degree}   \\  \\ x =  \frac{7 \times0.9876883406 }{0.6427876097}  \\  \\ x =  \frac{6.91381838}{0.6427876097}  \\  \\ x = 10.755992 \\  \\ x  \approx 10.8

Please answer !!!!!! Will mark brainliest !!!!!!!!
Inga [223]

Answer:

f(u) = 9/5

Step-by-step explanation:

u - 5 = -4(u - 1)      Distribute on the right side

u - 5 = -4u + 4

+4u      +4u            Add 4u to both sides

5u - 5 = 4

    + 5   + 5            Add 5 to both sides

5u = 9                    Divide both sides by 5

u = 9/5

How can I solve 4x-2>3x+5
cluponka [151]
You would move over the -2 making the equation look like this 4x>3x+7. Then move the 3x to the other side of the equation making it look like this 1x>7. Thus the answer is x>7.
