Answer:$400

Step-by-step explanation:

Let them original price be cp

Selling price=340

Percentage decrease=15

Percentage decrease=(cp-sp)/sp x 100

15=(cp - 340)/cp x 100

Cross multiplying

15cp=100(cp-340)

Opening brackets

15cp=100cp-34000

Collect like terms

100cp-15cp=34000

85cp=34000

Divide both sides by 85

85cp ➗ 85=34000 ➗ 85

cp=400

Subtract 37/55-32/55

The answer would be 5/55 because if you subtract 32 from 37 you would end up with 5 and because the denominator was the same you keep the denominator the same.

In the diagram B is the midpoint of a A and C. B is also the midpoint or E and F. C is the midpoint of A and D.
aivan3 [116]

Answer:

AD = 84

Step-by-step explanation:

Since B is the midpoint of AC then AB = BC = 2x - 5

Since C is the midpoint of AD then AC = CD, thus

AB + BC = CD, that is

2x - 5 + 2x - 5 = x + 29

4x - 10 = x + 29 ( subtract x from both sides )

3x - 10 = 29 ( add 10 to both sides )

3x = 39 ( divide both sides by 3 )

x = 13

Hence

AD = AB + BC + CD

     = 2x - 5 + 2x - 5 + x + 29 = 5x + 19, thus

AD = (5 × 13) + 19 = 65 + 19 = 84
