Answer:

1.

x <   -  \frac{5}{13}

2.

x \geqslant  -  \frac{1}{5}

Step-by-step explanation:

↷

- \frac{13}{16}x +  \frac{3}{8}  <  \frac{11}{16}  \\  \frac{  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  - \frac{3}{8 }    <   -   \frac{3}{8} }{ \frac{  -  \frac{13}{16}x }{   - \frac{13}{16} }   <   \:  \:  \:  \frac{ \frac { 5}{16} }{ -  \frac{ 13}{16} } }   \\  \\ x  <    \frac{ - 5}{ \: 13}

↷

\frac{1}{3}  \geqslant  \frac{2}{9}  -  \frac{5}{9} x \\  \frac{   -  \frac{  2}{9} \geqslant   -   \frac{2}{9} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   }{ \frac{ \:  \:  \:  \frac{1}{9}x }{  - \frac{ 5}{9} } \geqslant   \frac{  - \frac{5}{9} }{  - \frac{5}{9} }   }  \\  \\ x  \geqslant   -  \frac{1}{5}

In the isosceles triangle ABC, we have AB=AC=4. The altitude from B meets AC at H. If AH=3(HC) then determine BC.
Inga [223]

Answer:

BC=√7

Step-by-step explanation:

AC=4

AC=AH+HC

=3HC+HC

=4HC

HC=1/4AC=1/4×4=1

AH=3HC=3×1=3

BH⊥ AC

AB=AC=4

BC=\sqrt{AB^2-AH^2} =\sqrt{4^2-3^2} =\sqrt{16-9} =\sqrt{7}

Plzz hurry<br> 12/19(x-22)=38-6x-3
nadya68 [22]

Answer:

x = 929/126

Step-by-step explanation:

12/19(x-22)=38-6x-3

Combine like terms

12/19(x-22)=35-6x

Multiply each side by 19

19* 12/19(x-22)=19*(35-6x)

12( x-22) = 19*(35-6x)

Distribute

12x - 264 = 665 - 114x

Add 114x to each side

12x +114x - 264 = 665 - 114x+114x

126x -264 = 665

Add 264 to each side

126x-264+264 = 665+264

126x = 929

Divide each side by 126

126x/126 = 929/126

x = 929/126

Can someone explain this to me not only answers make sure to make it clean then i will mark brainliest please i really need an e
Igoryamba

Answer:

Since the sum of the angles equal to 720, you have to add all the angles to add to 720 and then solve for x, in which would look like this (x+2)+(x-4)+(x+6)+(x-3)+(x+7)+(x-8)=720, which is simplified to (6x)=720, in which will make x=120. Next, since its angle E, you plug in tha x value, (120+6), in which the ANSWER IS 126 DEGREES

Step-by-step explanation:

Hope this help ^w^

-2(bx - 5) = 16<br><br> What’s does b and x equal?
horrorfan [7]
To solve this problem you must apply the proccedure shown below:
 You have the following equation given in the problem above:
 <span>-2(bx - 5) = 16
</span> When you solve for bx, you have:
 <span>-2(bx - 5) = 16
 -2bx-10=16
 -2bx=26
 bx=26/-2
 bx=-13

 When you solve for b, you obtain:
 </span><span>-2(bx - 5) = 16
 -2bx=26
 b=-(26/2x)

 When yoo solve for x:
 </span>2bx=26
 x=-(26/2b)<span>

 </span>
