We can calculate EEE, the amount of euros that has the same value as DDD U.S. dollars, using the equation E=\dfrac{17}{20}DE=

Solnce55 [7]

Answer:

0.85 Euros have the same amount as 1 U.S dollar.

Step-by-step explanation:

Given : The equation $E= \frac{17}{20}D$

To find : Number of Euros which has same value as D U.S. dollar ?

Solution :

The equation $E= \frac{17}{20}D$

Where, E= amount of Euros

D= amount of U.S dollar.

Now for 1 U.S dollar we put D=1,

$E= \frac{17}{20}(1)$

$E= \frac{17}{20}$

$E= 0.85$

Therefore, 0.85 Euros have the same amount as 1 U.S dollar.

Points E, C, F are collinear and point C is in between. If EF = 14in and EC-9in, how long is CF?

Andreas93 [3]

Step-by-step explanation:

"collinear" means simply that they are all on the same line.

and that solves the problem right away, right ?

because as we know EF (the long distance between the outermost points) is 14 in, and EC (which is s part of the long distance) is 9 in, that means

CF (the rest of the long distance) = EF - EC = 14-9 = 5 in

What is the solution of the system?

gulaghasi [49]

Answer: $\bold{\text{b.}\bigg(4,-\dfrac{1}{2}\bigg)}$

Step-by-step explanation:

x - 2 = -4y → x = 2 - 4y

3x + 2y = 11

3(2 - 4y) + 2y = 11 replaced "x" with (2 - 4y)

6 - 12y + 2y = 11 distributed "3" on left side

6 - 10y = 11 added like terms (-12y + 2y)

- 10y = 5 subtracted "6" from both sides

y $= -\dfrac{1}{2}$ divided both sides by -10

Next, solve for x:

x = 2 - 4y

$= 2 - 4(-\frac{1}{2} )$

= 2 + 2

= 4
