Change the mixed leading number into an improper fraction...a b/c=(ac+b)/c

19/7-7/8  the least common multiple of the denominators is 56 so:

(19/7)(8/8)-(7/8)(7/7)

(152-49)/56

103/56  now we can change back into a mixed number...

(56+47)/56

1 47/56

PLEASE HELP<br><br> What is the value of x?
KonstantinChe [14]
Side JL is 4√2  recall that in a 30-60-90 right triangle the hypotenuse is 2 times the size of the short leg.

JL also serves as the hypotenuse of the 45-45-90 triangle JML.  The ratio of side lengths in this triangle is 1:1:√2

So we can see that the value of x = 4

How do I find the area of each shape
Ad libitum [116K]

Answer: the formula is (A=bh1/2)


Step-by-step explanation: #4 (The triangle)

First let’s find the base length of the triangle.

28 - 16 = 12

Ok now let’s do the real math now

Area  = bh1/2

Area = (12)(16)(1/2)

Area = 96

Don’t worry about the slant height it’s just there to trick you

Which statement is true about the given information?
Lubov Fominskaja [6]

Answer

∴ The true statement is Answer:

The true statement is BD ≅ CE  ⇒ 3rd answer

Step-by-step explanation:

- There is a line contained points B , C , D , E

- All points are equal distance from each other

- That means the distance of BC equal the distance of CD and equal

 the distance of DE

∴ BC = CD = DE

- That means the line id divided into 3 equal parts, each part is one

  third the line

∴ BC = 1/3 BE

∴ CD = 1/3 BE

∴ DE = 1/3 BE

∵ BC = CD

∴ C is the mid-point of BD

∴ BC = 1/2 BD

∵ CD = DE

∴ D is the mid-point of DE

∴ CD = 1/2 CE

- Lets check the answers

* BD = one half BC is not true because BC = one half BD

* BC = one half BE is not true because BC = one third BE

* BD ≅ CE is true because

 BD = BC + CD

 CE = CD + DE

 BC ≅ DE and CD is common

 then BD ≅ CE

* BC ≅ BD is not true because BC is one half BD

∴ The true statement is BD ≅ CE
