I think it would be y=5/6 - 5
<span>We already know that angles ECS and TRS are congruent, because they are both right angles (given). We also know that angles CSE and RST are congruent because they are vertical angles and vertical angles are always congruent. That gives us two sets of congruent angles. We just need to know something about one pair of sides to prove the two triangles congruent to each other. I do question the order of the letters in the names of the triangles--if that's really the order the letters are written in the problem, then we would need to know that ES is congruent to RT or that CS is congruent to ST. If the order of the letters of the names of the triangles is a little different we would need to know that CS is congruent to RS or that any of the other sides that appear to match are actually congruent. </span>
Answer:
m=5
Step-by-step explanation:
Let the number be represented by m.
Then twice the number m is represented as 2* m or 2m.
3 less than twice the number m = 2m -3
As per the question this value is 7.
Representing this in equation format:
=> 2m-3 = 7
=> 2m = 7+3 = 10
=> m= 10/2 = 5
Hence the number m is given by 5.
Verification:
Twice the number = 2* 5 = 10
3 less than twice the number m = 10 -3 = 7
This is the same as 7 as per the requirement.

Answer:
Step-by-step explanation:
The equation is 7(2x-1) - 11 = 6 + 6x
The equation is a linear equation because the highest power of x is one.
x is the variable and the numbers not containing x are constants
To solve the equation,
First step is to distribute. This involves opening up the bracket.
7(2x-1) - 11 = 6 + 6x will become
7×2x - 7×1 - 11 = 6 + 6x
14x - 7 - 11 = 6 + 6x
Next step is to combine like terms
14x -18 = 6 + 6x
Next step is to move the variable terms to the left hand side of the equation and move the constant terms to the right hand side of the equation. It becomes
14x - 6x = 6 + 18
8x = 24
x = 24/8 = 3
