Answer:

x = 20

Step-by-step explanation:

The 2 angles are vertical and congruent, thus

10x - 27 = 8x + 13 ( subtract 8x from both sides )

2x - 27 = 13 ( add 27 to both sides )

2x = 40 ( divide both sides by 2 )

x = 20

Answer:

(8x+13)=(10x-27) being vertically opposite triangles.

Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x

Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x

If u took a test that had 150 questions on it but didn’t finish 27 of the questions, what percentage of the questions did u answ

Alenkinab [10]

Answer:

82%

Step-by-step explanation:

Total number of questions = 150

Questions not answered = 27

questions answered = 150 - 27 = 123

percent questions answered

= (questions answered / total questions ) x 100%

= (123/150) x 100%

= 82%

Answer:

T mBAC = mB'A'C'

F 2mABC = mA'B'C'

F BC = 2B'C'

T 2XA = XA'

D'(-2/3; -1)

E'(-1;1)

F'(1;1)

G'(1;-1)

the centre is L(0;-2)

the scale factor is 4

length J'K' = 4JK

the measure of L is equal the measure of L'

the table:

K(4;2) 4 4 16 16 0+16 -2+16 K'(16;14)
