How do u solve (2d-5)/2 = (5d+2)/9

Rzqust [24]

Answer:

D= 49/8

Step-by-step explanation:

Cross-multiply.

(2d-5)/2 = (5d+2)/9

(2d−5)*(9)=(5d+2)*(2)

18d−45=10d+4

Subtract 10d from both sides.

18d−45−10d=10d+4−10d

8d−45=4

Add 45 to both sides.

8d−45+45=4+45

8d=49

Divide both sides by 8.

d= 49/8

So the answer is 49/8

I hope it's right!

Answer:

The carnival is losing (on average) $0.15 on each play

Step-by-step explanation:

To find out how much the carnival wins or looses in each play one subtract the expected value (EV) from each play from the amount charged by the carnival for each play ($0.55). If the expected value is higher than what the carnival charges, the carnival is losing money.

Expected is the sum of the payouts of each bet multiplied by its likelihood:

$EV= \frac{64*0.40+25*1.15+1*9.00}{90}\\EV= 0.70$

Since the expected value is higher than $0.55, the carnival is losing money, on average, on each play:

$0.55-0.7 = -0.15$

The carnival is losing (on average) $0.15 on each play

Parallelogram ABCD is a rectangle.

viktelen [127]

Answer:

$AC=BD$

$AB\perp BC$

Step-by-step explanation:

A parallelogram is a quadrilateral (4-sided polygon) that has two pairs of parallel sides.

In this sense, this figure shows a especial parallelogram called <u>rectangle</u>, since its four sides form right angles ( $90\°$ ).

Hence:

$AB\parallel DC$

$AD\parallel BC$

$AB=DC$

$AD=BC$

$AB\perp BC$

$AD\perp DC$

So, the correct choices among the given options are:

$AC=BD$

$AB\perp BC$

The equation y = 14.3x + 17.1 estimates the amount that businesses will spend, in billions of dollars, on a certain business tec

svetlana [45]

2006 and later

First, plug in 60 for y. Then subtract 17.1 from both sides, and you get 42.9 = 14.3x, from which you divide 14.3 from both sides to isolate x. Since x = 3, the businesses will be spending less than or equal to $60 billion up to 3 years after 2002. The fourth year, which is 2006, will be greater than $60 billion
