Answer:
Option D.
Step-by-step explanation:
Diagram is missing, let as consider the diagram of this question is shown below.
If a transversal line intersect two parallel lines, then the alternate exterior angles are equal.
From the given figure it is clear that both angles alternate exterior angles. It means measure of both angles are equal.
Subtract 20x from both sides.
Subtract 11 from both sides.
The value of x is 5.
Measure of each angle is
Therefore, the correct option is D.
Answer:
D is the correct answer
Step-by-step explanation:
Answer:
7(x-2)=5(x+4)
7x-14=5x+20
7x-5x=20+14
2x=34
x=17
7(x - 2) = 5(x + 4)
Multiply the first bracket by 7
(7)(x)=7x
(7)(-2)=-14
Multiply the second bracket by 5
(5)(x)=5x
(5)(4)=20
7x-14=5x+20
Move 5x to the other side. Sign changes from -5x to +5x.
7x-5x-14=5x-5x+20
7x-5x-14=20
2x-14=20
2x-14+14=20+14
2x=34
Divide both sides by 2
2x/2=34/2
Answer: x=17
Integers are numbers like ...-3, -2, -1, 0, 1, 2, 3... and so on. So, according to this definition, let's solve this problem:
28. We know that the product of three integers is -3. So, the statement states that we have three factor, so:
a.b.c = -3
The possible values of the factors are:
(3)(1)(-1) = -3
(-3)(1)(1) = -3
29. In this problem we know two nonzero integers, that is, they cannot be equal to zero. Thus, they must have different sign, that is, one of them must be positive and the other negative.For instance:
(-9)(2) = -18, So -18 is less than -9 and 2
Another example:
(1)(-8) = -8, So -8 is equal to -8 and -8 is less than 1.
30. The sign of the product of two integers with the same sign is positive, that is:
(+)(+) = (+) and
(-)(-) = (+)
So, the sign of the product of three integers with the same sign are two options:
(+)(+)(+) = (+), So the sign of the product is positive
(-)(-)(-) = (-), So the sign of the product is negative.
This option two gives us that result because:
(-)(-) = (+) and (+)(-) = (-)
