The ordered pair is only a solution to the first equation, so it is not a solution to the system.

2 x 10 = 20    5 x 5 = 25    20 - 25 = -5     True!

10 + 2 x 5 = 11?    False!    10 + 2 x 5 = 20

So, A and C are the correct answers!

PLEASE ANSWER!!!!!! REALLY IMPORTANT
faust18 [17]

<u>Answer-</u>

<em>The height of the prism is</em><em> 6 units</em>

<u>Solution-</u>

As the base of the prism is a hexagon consisting of 2 congruent isosceles trapezoids.

So,

V_{Prism}=Area_{Base}\times Height

And,

Area_{Base}=2\times \text{Area of the trapezoid}

Also,

\text{Area of the trapezoid}=\dfrac{1}{2}\times \text{Height}\times (\text{Sum of two parallel lines})

=\dfrac{1}{2}\times 3\times (5+8)\\\\=\dfrac{39}{2}

Putting all the values,

V_{Prism}=2\times \dfrac{39}{2}\times Height=39\times Height

As the volume is given, so

\Rightarrow 39\times Height=234

\Rightarrow Height=\dfrac{234}{39}=6

14x + 6 = 5x - 3 with solution
Schach [20]

hey there

the answer is

14x + 6 = 5x + -3


6 + 14x = 5x + -5

6 + 14x = -3 + 5x


6 + 14x + -5x = -3 + 5x + -5x


Combine like terms: 14x + -5x = 9x

6 + 9x = -3 + 5x + -5x


Combine like terms: 5x + -5x = 0

6 + 9x = -3 + 0

6 + 9x = -3

6 + -6 + 9x = -3 + -6


Combine like terms: 6 + -6 = 0

0 + 9x = -3 + -6

9x = -3 + -6


Combine like terms: -3 + -6 = -9

9x = -9


Divide each side by '9'.

x = -1


Simplifying

x = -1

thank you

Find the value of each variable in the parallelogram.
Nikitich [7]

Answer:

u = 4; v = 18

because this is a parallelogram

=> 2u + 2 = 5u - 10

6 = v/3

<=> 3u = 12

v = 6.3

<=> u = 4

v = 18
