According to triangle proportionality theorem:

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

And in the given triangle, MN parallel to BC, So MN divided the two sides in proportion, that is

\frac{MB}{AM}=\frac{NC}{AN}

Correct option is the third option .

Answer the following equations:
Andrew [12]

Step-by-step explanation:

3(t+5) = 9

3t+15 = 9

3t = -6

t = -2

2(f-7) = -10

2f - 14 = -10

2f = 4

f = 2

-(c - 9) = 4

-c + 9 = 4

-c = -5

c = 5

-6(2t + 8) = -84

-12t - 48 = -84

-12t = -36

12t = 36

t = 3

-10 (s + 2) = -57

-10s - 20 = -57

-10s = -37

s = 3.7

7(3w + 8)/3 = -9

By cross multiplication,

7(3w + 8) = -27

21w + 56 = -27

21w = -83

w = -3.95

35/5 = (F - 32)/9

7 = (F - 32)/9

By cross multiplication,

63 = F - 32

63 + 32 = F

95 = F

Convert 185 degrees Celsius to degrees Fahrenheit. Round<br> your answer to the nearest degree
lakkis [162]

Hello! :3

Answer:

The Correct Answer is <u><em>365 °F</em></u>

Step-by-step explanation:

The C to F formula is(C ~x~ 9/5) + 32 = F

When we do 185 for C in the formula, we get(185 ~x~ 9/5) + 32 = F.

To solve,  (185 ~x~ 9/5) + 32 = F. we first multiply 9 by 185, then we divide the product by 5, and then finally we add 32 to the quotient to get the answer.

185~x~9=1665

1665  /5=333

333+32=355

Therefore, the answer to 185 C to F is 365 which can be written like this

⇒ 185 °C = 365 °F

hope this helps you!

Have an Awesome Thursday!

eduard
Answer

Rebecca has 76 comic books
Maurice has 54 comic books

Step-by-step

Since there are 54 fewer comics and together they have 130 comics, you should subtract 54 from 130. Once you do that your answer will be 76; and that is how many comics Rebecca has. And 76+54=130 so Maurice has 54 comics
