SOME ONE PLEASE HELP!! step by step explanation
leva [86]

2.) 4y = 2y - 10 - 2

--> 4y = 2y - 8 --> 4y - 2y = -8 --> 2y = -8

So y = -4.

3.) 6x - 9x - 4 = -2x - 2

Combine like terms:

--> -3x - 4 = -2x - 2

Isolate x ---> -3x - (-2x) = -2 - (-4)

----> -x = 2

So x = -2

4.) -2(2x + 3) = -4(x + 1) - 2

--> -4x - 6 = -4x - 4 - 2

Combine like terms ---> -4x - 6 = -4x - 6

This equation has many possible solutions.

5.) 3(x + 2) = -5 - 2(x - 3)

--> 3x + 6 = -5 - 2x + 6

Combine like terms ---> 3x + 6 = -2x + 1

----> 3x + 2x = 1 - 6

-----> 5x = -5

So x = -1.

6.) 2(x - 3) = \frac{1}{2}(4x - 12)

Distribute ---> 2x - 6 = 2x - 6

This equation has many possible solutions.

Answer:

{5}^{ \frac{5}{6}}

Step-by-step explanation:

( \sqrt{5} )( \sqrt[3]{5}) \\  \\  =  ({5}^{ \frac{1}{2} } ).({5}^{ \frac{1}{3} } ) \\  \\  = {5}^{ \frac{1}{2}  +  \frac{1}{3} }  \\  \\  = {5}^{ \frac{3 + 2}{2 \times 3}}  \\  \\  \huge \red{ \boxed{ = {5}^{ \frac{5}{6}} }}

The surface area of two hemispheres are in the ratio 64: 121. Find the ratio of<br> their radii
Blababa [14]

Answer:

5:7

Step-by-step explanation:

Let the radius of first hemisphere be 'r' units

Let the radius of second hemisphere be 'R' units

2 x \piπ x r^2 / 2 x \piπ x R^2 = 25 / 49

r^2 / R^2 = 25 / 49

r / R = 5 / 7

the ratio of radii is 5:7.
