8 to 11 do it with equations thx
Alenkasestr [34]

Answer:

Step-by-step explanation:

8. 4\geq x+\frac{3}{4}

4(4\geq x+\frac{3}{4} )

16\geq 4x + 3

-3         -3

13\geq 4x

\frac{13}{4}\geq \frac{4x}{4}

\frac{13}{4} \geq x = x\leq \frac{13}{4}

x\leq \frac{13}{4}=3.25

9. x-3\leq -8

       +3     +3

x\leq -5}

10. 4\leq x-7

  +7         +7

11\leq x=x\geq 11

11. 6.9 < x - 2.3

 + 2.3      + 2.3

 9.2 < x = x > 9.2

Hope this helps!

Solve Triangle DEF. - Math
Brrunno [24]

Answer:

p = 52.942259755149776

Step-by-step explanation:

This is basic trigonometry.

\cos(39)  =  \frac{e}{22}

e =  \cos(39)  \times 22

\sin(39)  =  \frac{d}{22}

d =  \sin(39)  \times 22

And finally perimeter (p):

p = 22 +  e+ d

Mrs Ang bought k apples at 50% each from a supermarket. How much
timama [110]

Answer:

The apples may have costed 0.50 cents each, and she may have bought 10, which would result in her paying 10 dollars, and receiving 5 dollars in change.

Step-by-step explanation:

Multiply 10 (the amount she gave to the cashier) by 0.50%, it equals 5, so that's how much she paid, and since she gave a 10 dollar bill, she should get 5 dollars in change.
