The question is asking you to come up with a real-life example of something that can be represented as 15+ c= 17.50. If I were you I would do sales tax. You bought an item with a 15 dollar price tag, but when you go to check out 2.50 are added in tax to equal 17.50. to solve subtract 15 from 17.50: c= 2.50. Your variable (c) represents the sales tax. Hope that helps! :)

las edades de maría y susana suman 56 años si la edad de maría es los 3/5 de la edad de susana ¿ que edad tiene maría?

Murljashka [212]

Susana=s
maria=m

m= 3s/5

s+m=56
s+(3s/5)=56
(5s+3s)/5=56
8s=56*5
8s=280
s=280/8
s=35

35 --->5/5
x ---> 3/5

x= (3/5)*35 / (5/5)
x=21
edad de maria= 21 años

A box is filled with 2 blue cards, 4 brown cards, and 6 yellow cards. A card is chosen at random from a box. What is the probabi

Finger [1]

Answer:

Therefore the probability that the card is not brown is $\frac12$ .

Step-by-step explanation:

Probability: Probability is the ratio of the favorable outcome to the total outcome.

$Probability =\frac{\textrm{Favorable outcome}}{\textrm {Total outcome}}$

Given that, a box contains 2 cards blue in color , 4 cards brown in color and 6 cards yellow in color.

Total number of cards= (2+4+6)=12

∴P(getting a brown card)

$=\frac{\textrm{No. of brown card}}{\textrm{Total no. of card}}$

$=\frac{6}{12}$

$=\frac12$

∴P(not getting a brown card)

=1 - P(getting a brown card)

$=1-\frac12$

$=\frac12$

Therefore the probability that the card is not brown is $\frac12$ .

taurus [48]

Answer: 34 meters.

Step-by-step explanation;

Step One. Find the value of the width. Use an equation with w representing the width and the two values you already have. 9 meters x w = 72 square meters.

Step Two. Solve for width. This is w = 8.

Step Three. Use the value for width in a perimeter formula to calculate the perimeter; 9(2) + 8(2). <em>This is 34 meters for perimeter</em>.
