Question 5(Multiple Choice Worth 1 points)
Anit [1.1K]

Answer:

x+3x+5=101 (Option C).

Step-by-step explanation:

This question requires to be solved using the supposition method.

Let Aylen's savings be $x. Therefore, Rich's savings would be $(3x+5). This is because it is mentioned that Rich has $5 more than 3 times the amount of money Aylen has. The sum of the savings is $101. Therefore the sum of the savings of Aylen and Rich is given by:

x + 3x + 5 = 101. Thus, Option C is the correct answer.

Solve the equation for x gives x = $24. This is Aylen's share. To calculate Rich's share, simply put x=24 in 3x+5. Thus, Rich's share will be $77.

In short, Rich's share = $77, Alan's share = $24, and this has been calculated using the equation x+3x+5=101 (Option C)!!!

How do I find the factoring Trinomials
atroni [7]
First, you have to find which two numbers go into 24 when multiplied.

24=
6×4
2×12
24×1
-6×4
-2×12
-24×1

Then you add each set of numbers together.

6+4=10
2+12=14
24+1=25
-6+4=-2
-2+12=10
-24+1=-23
6+(-4)=1
2+(-12)=-10
24+(-1)=23

Then you find which set when added makes 4. Since none of these are 4, it is no solution.
