Answer:

y = 4x

(x = Elliot's money, y = yours)

y = 1/2x

(y = how many pages you read, x = George's amount of pages)

w = l - 4

(w = width, l = length)

5c + 12 = p

(c = cd, p = price)

*note I used a constant since it clearly said 12$

Suppose two dice (one red, one green) are rolled. Consider the following events. A: the red die shows 1; B: the numbers add to 4

kirill115 [55]

Answer: Third option is correct.

Step-by-step explanation:

Since we have given by

Event A: the red die shows 1

Event B : the numbers add to 4

Event C: at least one of the numbers is 3

Event D : the numbers do not add to 9.

D' means the number add to 9.

We need to write the following statement in symbolic form:

Either the numbers add to 9 or the red die shows a 1.

So, it becomes,

$D'\cup A$

Number of elements in D'∪A = 1.

Hence, Third option is correct.

When twice a number is subtracted from 29 the result is 21 find the number

Gre4nikov [31]

X= a number

29 - 2x= 21
subtract 29 from both sides
-2x= -8
divide both sides by -2
x= 4

CHECK:
29 - 2x= 21
29 - 2(4)= 21
29 - 8= 21
21= 21

ANSWER: The number is 4.

Hope this helps! :)
