Answer:

9/29

Step-by-step explanation:

If you add all of the cards together, you will get thirty. But when you take one red card out, you get 29. Since there are 9 orange cards, then there is a 9 out of 29 chance.

i have two questions. Is y= (4 2/3) x proportonal? and is y= 3(x - 1) proportional? If it’s proportional, what’s the constant va

bear in mind that, direct proportional equations have a y-intercept.

for y = kx, is pretty much y = kx + 0, where 0 = y-intercept.

and the "k" constant of proportionality, is pretty much just its slope.

Find the value of x and y
velikii [3]

Answer:

2x + 20 = 3x-10

2x -3x = -20-10

-x = -30

x= 30

Checking part:

2x+20 = 2(30) +20 = 60+20 = 80

3x-10 = 3(30) - 10 = 90-10 = 80

Hence, the final answer is x = 30.

Rearrange your equation to isolate a:(a+b/c)(d-e)=f
sukhopar [10]
To rearrange the equation given, we need to take note the rules in adding, subtracting, multiplying and dividing terms. We rearrange the equation as follows:

<span>((a+b/c)(d-e)=f) 1/(d-e)

</span>(a+b/c = f/(d-e))c

a+b = fc/(d-e)

a = [fc/(d-e)] - b

Hope this answers the question.
