Answer:
x = 25
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
That is ∠ D and ∠ B are corresponding angles and congruent, thus
4x - 20 = 2x + 30 ( subtract 2x from both sides )
2x - 20 = 30 ( add 20 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25
3(4x - 3) - 7x = 5x - 9
First, expand your equation so it will be easier to simplify.
Second, multiply (3)(4x) to get 12x.
Third, multiply (3)(-3) to get -9.
Fourth, combine the like terms. (x and -9 alone).
Fifth, subtract (12x + -7x) to get 5x.
Sixth, change 5x + -9 into a subtraction.
Seventh, since both sides are equal, that means that the equation has infinite solutions.
Answer:
B) infinite solutions
Answer:
4
Step-by-step explanation:
125=5+30r
125-5=30r
120=30r
120÷30= 4
