1st rearrange the terms. then subtract 36 in both sides.then you will get 94=7x then simplify by dividing by 7. then you will get 13.4285714286. which if you round up maybe its 94/7.

Answer: x = 2

Step-by-step explanation: the interior angles of a rhombus add to 360 degrees and since half of 360 is 180, create the equation 130 + (36 +7x) and set it equal to 180. when solved 130 + (36 +7x) = 180 you get x =2

Given equations A and B as 2/5x+y=12 and 5/2y-x=6 respectively which expression will eliminate the variable X a) 5/2A+2/5B b)5/2

frutty [35]

Answer:

C) $A+\frac{2}{5}B$

Step-by-step explanation:

Given Equations:

A) $\frac{2}{5}x+y=12$

B) $\frac{5}{2}y-x=6$

In order to eliminate $x$ we need to multiply $\frac{2}{5}$ to equation B and add it to A.

Multiplying $\frac{2}{5}$ to B.

⇒ $\frac{2}{5}\times (\frac{5}{2}y-x)=\frac{2}{5}\times 6$

⇒ $(\frac{2}{5}\times\frac{5}{2}y)-(\frac{2}{5}x)=\frac{12}{5}$

⇒ $y-\frac{2}{5}x=\frac{12}{5}$

Adding it equation A.

$\frac{2}{5}x+y=12$

+ $-\frac{2}{5}x+y=\frac{12}{5}$

We get $2y=\frac{72}{5}$

Thus $x$ is eliminated.

So, the expression used to eliminate $x$ is:

$A+\frac{2}{5}B$
