Answer:

Step-by-step explanation:

Line DE is parallel to line AG.

Also, triangle ABG is similar to triangle to triangle DBE.

Therefore,

AB/DB = GB/EB = AG/DE

AB = 5 + 6 = 11

GB = 9 + x

Therefore,

11/6 = (9 + x)/9

Cross multiplying, it becomes

11 × 9 = 6(9 + x)

99 = 54 + 6x

Subtracting 54 from the Left hand side and the right hand side of the equation, it becomes

54 - 54 + 6x = 99 - 54

6x = 45

Dividing the Left hand side and the right hand side of the equation by 6, it becomes

6x/6 = 45/6

x = 7.5

Answer:

The dimensions of the park on the scale drawing are 12 inches by 20 inches

The actual dimensions are given as:

Park = 600 feet by 1000 feet

Swing set = 25 feet by 100 feet

The dimension of the swing set on the scale drawing is given as: 0.5 inch by 2 inches

The above means that, the scale factor (k) is:

--- i.e. divide the scale measurement by the actual measurement

Evaluate both equations

So, we have:

Multiply the scale factor by the dimensions of the park, to get the scale measurement

Hence, the dimensions of the park on the scale drawing are 12 inches by 20 inches

What is the value of –112.84 – 54.14 – (–29.18)?
-BARSIC- [3]

For this case we must find the value of the following expression:

-112.84-54.14 - (- 29.18) =

The law of the signs of multiplication states that:

- * - = +\\-112.84-54.14 + 29.18 =

We add similar terms, taking into account that equal signs are added and the same sign is placed, while different signs are subtracted and the sign of the major is placed.

-166.98 + 29.18 = -137.8

Answer:

-137.8
