Answer:

x = 15

Step-by-step explanation:

Llamaremos x al número que buscamos, entonces:

la mitad de x es  x/2, la tercera parte es x/3, y el triple del número es 3*x

De acuerdo al problema :

(x/2 - x/3 ) + 85/2  = 3*x

Esta es una ecuación de primer grado pasamos a resolverla.

( 3*x  -  2*x ) /6   + 85/2  = 3*x

x/6 + 85/2 = 3*x

( x + 255)/6 = 3*x

x  +  255  = 18*x

17*x  = 255

x  = 255/17

x = 15

URGENT!! GEOMETRY TRANSLATIONS. INCLUDE EXPLANATION IF POSSIBLE
STatiana [176]

First find the new coordinates for P and Q after the translations:

P'(2 + 3, 4 - 4) = P'(5, 0)

Q'(-3 + 3, 2 - 4) = Q'(0, -2)

Now, find the slope from this:

(0 - (-2))/(5 - 0) = 2/5

The slope has remained the same. It is important to note that after any translation, the slope will always remain the same. However, this is not always so for rotations and reflections.

rosijanka [135]

Answer:

$9398.50

Step-by-step explanation:

Given

\$1 = 106.40\ ALL

Required

Equivalent of 1,000,000 ALL

We have:

\$1 = 106.40\ ALL

and

\$x = 1000000\ ALL

Cross Multiply

x * 106.40 = 1 * 1000000

106.40x = 1000000

Solve for x

x = 1000000/106.4

<em></em>x = \$9398.50<em> -- Approximated</em>

Marina86 [1]

Answer:

36 fries

Step-by-step explanation:

Michael has a probability of 0.3.

Lidia has a probability of 0.1.

Alexandra has the probability of 0.32.

Catherine has the probability of 0.1.

Let the probability of Ronald be x

Sum of all the probabilities must be 1

So, 0.3+0.1+0.32+0.1+x=1

0.82+x=1

x=0.18

So, probability of Ronald is 0.18

We are given that here are 200 fries in the basket.

So, the number of fries that Ronald will eat = 0.18 \times 200 =36

Hence Ronald will eat 36 fries.
