lorasvet [3.4K]

Answer:

The value of x is 7

Step-by-step explanation:

we know that

If two figures are congruent, then the corresponding angles and the corresponding sides are equal

In this problem

Triangles ABC and DEF are congruent

ABC≅DEF

therefore

AB=DE ----> equation A

AC=DF ----> equation B

BC=EF ----> equation C

Substitute the given values in the equation B

8=2x-6

Solve for x

2x=8+6

2x=14

x=7

therefore

The value of x is 7

60&gt;5(6-2x) ok help me so I can get an answer
Dima020 [189]

Inequalities are used to represent unequal expressions

The solution to the inequality is: x > -3

<h3>How to determine the inequality solution</h3>

The inequality is given as:

60>5(6-2x)

Rewrite the inequality properly as:

60>5(6-2x)

Divide both sides of the inequality by 5

12>6-2x

Subtract 6 from both sides of the inequality

6>-2x

Divide both sides of the inequality by -2

-3Rewrite the inequality as[tex]x > -3

Hence, the solution to the inequality is: x > -3
