Please help me with 6-8 (step by step please)

Mathematics

NISA [10]3 years ago

6. Supplementary means when added together they equal 180 or a straight line.
So ∠A+∠B=180
6X+8+10x-20=180
16x-12=180
16X=192
X=12.
∠A=6(12)+8
∠A=72+8=80←
∠B=10(12)-20
∠B=120-20=100←

7. If j is between H and K then HJ+JK=HK
(8x-3)+(12x-5)=112
20X-8=112
20x=120
X=6←
Line HJ=8(6)-3
Line HJ=42-3=39←
Line JK=12(6)-5
Line JK=72-5=67←

8. Vertical angles are the "no adjacent angles" that are formed when two lines intersect, like ∠LSO and the one directly across from it (can't see those letters) or the angles on the top with S in it and directly under it.

:) I hope I helped :)

elena-14-01-66 [18.8K]

Answer:

a)45min

b)900min

Step-by-step explanation:

We were told that it takes Matt 3 minutes to read one page in a book.

It implies that 3minutes = 1page of the book

Then he continues to read at the same pace, he can read 15 similar pages in minutes.

a)Then, he can read 15 similar pages in

15x3 minutes.which is 45minutes.

b)Then if the book has 300 pages, it will take him. 300×3 minutes to read it.which is 900mins

Can someone help me with this question please.....
Alex73 [517]

Answer:

y = 541

Step-by-step explanation:

The mean is calculated as

mean = \frac{sum}{count}

Mean of set A = \frac{281+268+225+290}{4} = \frac{1064}{4} = 266

ratio between means = 7 : 12, then

mean of set B = \frac{12}{7} × 266 = 456 , thus

\frac{392+512+413+422+y}{5} = 456 ( multiply both sides by 5 )

1739 + y = 2280 ( subtract 1739 from both sides )

y = 541

50 points :] !!
nasty-shy [4]

Given,

LP = 15, PR = 9

Point P lies on the line segment PR. It would mean that,

LP + PR = LR

⇒LR = 15 + 9

⇒ LR = 24

Hence, "LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution" is the correct option.
