In the following diagram line CF is parallel to line CD. Segment DE has a length that is 4 inches greater than the length of CD.
Viefleur [7K]
Answer: CD = 10

Identify the given information. 
FG = 15
GE = 21
FE = 36
CD = x
DE = x + 4

Form your equation. Due to the Side-Splitter Theorem, FG/GE = CD/DE.
15/21 = x/x + 4

Cross-multiply and solve.
15(x + 4) = 21x            Distributive Property
15x + 60 = 21x           Subtract 15x from both sides
60 = 6x                      Divide by 6 to both sides
x = 10                         Answer!

I need help .........
seraphim [82]

Answer:

Step-by-step explanation:

Lets break each problem down before we answer it so it help to understand what we are looking for.

Vocabulary:

  Unit Rate: how many units of the first type of quantity corresponds to one unit of the second type of quantity. (12 inches to 1 foot)

Unit Rates:

Problem 1: Top left

A boy delivers 189 papers in 3 hours

\frac{189 papers}{3 hours} \\189/3\\\frac{63 papers}{1 hour}

Unit Rate: 63 papers delivered per hour

In simple terms, all we are doing is creating a fraction then simplifying it :)

Problem 2: Top right

It costs $8.40 for 12 cupcakes

\frac{8.40}{12 cupcakes} \\8.40/12\\\frac{0.70}{1 cupcake}

Unit Rate: For every $0.70, it costs one cupcake

Problem 3: Bottom left

5 miles in 50 minutes

\frac{5 miles}{50 minutes} \\5/50\\\frac{1 mile}{10 minutes}

Unit Rate: For every one mile ran, it takes 10 minutes

Problem 4: Bottom right

375 passengers distributed between 5 cars

\frac{375 passengers}{5 cars} \\375/5\\\frac{75 passengers}{1 car}

Unit Rate: For ever 75 passengers, there is one car

Hope this Helps!
