X – 7y = –11<br> 5x + 2y = -18
laiz [17]

Answer:

hope this help you

Step-by-step explanation:

Simplifying

X + -7y = -11

Solving

X + -7y = -11  

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '7y' to each side of the equation.

X + -7y + 7y = -11 + 7y

Combine like terms: -7y + 7y = 0

X = -11 + 7y

Simplifying

X = -11 + 7y

------------------------------------------------------------------------------------------------------------

Solving

5x + 2y = -18

Solving for variable 'x'.

Add '-2y' to each side of the equation.

5x + 2y + -2y = -18 + -2y

Combine like terms: 2y + -2y = 0

5x = -18 + -2y

Divide each side by '5'.

x = -3.6 + -0.4y

Simplifying

x = -3.6 + -0.4y

NEED HELP PLEASE SOLVE. due in 20 mins!
3241004551 [841]
Ok, so I’m pretty sure that would be a little less than 7 minutes because if 5 min is -150 degrees then 1 min is around 25 degrees. So around 7 min would be the answer.

Find the area of this rhombus
Vikentia [17]
<h2>Hello!</h2>

The answer is:

The area of the rhombus is equal to 64 squared inches.

area=64in^{2}

<h2>Why?</h2>

Since we already know half of the length of the diagonals of the rhombus, we can calculate the area of the rhombus using the following formula:

area=\frac{diagonal_{1}*diagonal_{2}}{2}

From the image we can see that:

diagonal_{1}=8in+8in=16in

diagonal_{2}=4in+4in=8in

So, substituting, we have:

area=\frac{16in*8in}{2}=\frac{128in^{2} }{2}=64in^{2}

Hence, we have that the area of the rhombus is equal to 64 square inches.

Have a nice day!
