Answer:

The similarity statement: FGHI ~ BCDE

Similarity ratio: 5:1

Step-by-step explanation:

The similarity statement is quite obvious, as there are only two rectangles shown, and the other one is "BCDE".

The similarity ratio is 5:1 because everything in the 1st (FGHI) rectangle is multiplied 5 times the values in the 2nd (BCDE) rectangle.

Given:

The two equations are $2x-5y=-7$ and $5x-3y=11$

We need to solve the equations using elimination method.

Elimination method:

Let us multiply the equation $2x-5y=-7$ by 5, we get;

$10x-25y=-35$ ---------(1)

Now, multiplying the equation $5x-3y=11$ by -2, we get;

$-10x+6y=-22$ --------(2)

Adding equations (1) and (2), we have;

$\ \ \ 10x-25y=-35\\-10x+\ \ 6y=-22\\---------\\-19y=-57$

$y=3$

Thus, the value of y is 3.

Substituting $y=3$ in the equation $2x-5y=-7$ , we have;

$2x-5(3)=-7$

$2x-15=-7$

$2x=8$

$x=4$

Thus, the value of x is 4.

Hence, the solution of the system of equations is (4,3)

Therefore, Option A is the correct answer.

What is x when 2(x+3)=x-4

denpristay [2]

Answer:

$x=-10$

Step-by-step explanation:

First, use distribution to simplify

$2(x+3)=x-4\\2x+6=x-4$

Then, simplify further by combining like terms

$2x+6=x-4\\2x+10=x\\10=-1x$

Solve

$10=-1x\\x=-10\\$
