Line d is parallel to line c in the figure below.
Parallel lines d and c are intersected by lines q and p to form 2 triangles. At lines d and p, the angle is 2, at d and q, the angle is 1, and at q and p the angle is 3. At lines c and q, the angle is 4, at p and c, the angle is 5, and the third angle is 6.
Which statements about the figure are true? Select three options.
Vertical angles prove that Angle 2 is congruent to angle 5.
In the two similar triangles, Angle 1 and Angle 4 are alternate interior angles.
Vertical angles prove that Angle 3 is congruent to angle 6.
The triangles are similar because alternate interior angles are congruent.
In the two similar triangles, Angle 2 and Angle 4 are corresponding angles.
The triangles are similar because corresponding sides are congruent.

SELECT ALL the expressions that are equivalent to -2(4 - 3x) + (5x - 2)
A.) 2x - 10
B.)11x - 10
C.)-8 + 11x - 2
D.)-8 - 11x - 2
E.) -8 + 6x + 5x - 2
F.)-8 - 3x + 5x - 2
Answer:
option B
Step-by-step explanation:
-2(4 - 3x) + (5x - 2)=
-8+6x+5x-2= 11x -10
-8 + 6x + 5x - 2 and 11x-10 are the equivalent expressions of the given expression -2(4 - 3x) + (5x - 2)
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is -2(4 - 3x) + (5x - 2)
We have to find the equivalent expression
x is the variable in the expression
Equivalent expressions are expressions that work the same even though they look different.
Let us apply distributive property
-8+6x+5x-2
Combine the like terms
11x-10
Hence, -8 + 6x + 5x - 2 and 11x-10 are the equivalent expressions of the given expression -2(4 - 3x) + (5x - 2)

Answer:
Im pretty sure that if you can go on it then divide it by the mian number you get the answer
Step-by-step explanation:
Answer:
the inequality is 500 - 25x >= 200
this insures that she will have at least 200 at the end of the summer.
subtract 200 from both sides of that inequality and add 25x to both sides of that inequality to get 500 - 200 >= 25x
simplify to get 300 >= 25x
divide both sides of that equation by 25 to get 300 / 25 >= x
simplify to get 12 >= x
12 >= x means x <= 12.
when x is smaller than or equal to 12, she will be guaranteed to have at least 200 in the account at the end of the summer.
when x = 12, what is left in the account is 500 - 25 * 12 = 200.
when x = 11, what is left in the account is 500 - 25 * 11 = 225.
when x = 13, what is left in the account is 500 - 25 * 13 = 175.
the maximum number of weeks he can withdraw money from her account is 12.
