ABCD ≅ FGHJ. Find the measure of the given angles or lengths of the given sides. CD = 2x + 3; HJ = 3x + 2.
xenn [34]
The question asks for the length of CD and HJ. To find those, we need to find a connection between them.

In the given statement, it says ABCD ≅ FGHJ. When we look at the equation, the corresponding letters are equal. For example, angle A is congruent to Angle F. Or BC ≅ GH.

So we know that CD and HJ are congruent.
Set them equal:
2x + 3 = 3x + 2
Subtract 2x from both sides:
3 = x + 2
Subtract 2 from both sides:
x = 3
If x is 3, plug it in:
3(3) + 2
Simplify:
9 + 2 = 11

So, HJ is 11. And because HJ ≅ CD, CD is 11 too.

What is the y-value of the solution to the system of equations {3x+4y=42x−4y=6?
timofeeve [1]

The value of y for the system of equation is -1/2 .

<h3>What is a System of Equation ?</h3>

A system of equation is a set of equation that have common solution

The set of equation given is

3x+4y=4

2x−4y=6

To solve the system , Elimination method will be used

Add equation 1 and 2 to eliminate y

5x  = 10

x = 2

Substitute the value of x in equation 1 to determine y

3x +4y = 4

6 + 4y = 4

4y = -2

y = -1/2

Therefore the value of y for the system of equation is -1/2 .
