The right answer is Option D.
Step-by-step explanation:
Let,
Kyle's money = x
Hayden's money = y
Jeremy's money = z
According to statements;
Kyle has three times as much money in his savings account as Hayden.
x = 3y Eqn 1
Hayden has twice as much money in his savings account as Jeremy.
z = 2y Eqn 2
Combined Kyle, Hayden, and Jeremy have a total of $612.
x+y+z=612 Eqn 3
Putting value of x and z from Eqn 1 and 2 in Eqn 3
Dividing both sides by 6
Putting in Eqn 1;
Kyle has $306 in his account.
The right answer is Option D.

Whenever we need to prove something, our first step is to write the given statements and then the second step is to write what we have to prove.
So out of the given two options, the correct option is the first option, that is , given .
If xy=0, assume that x and/or y=0
so we already gots factored
therfor
assume
3n-2=0 and 4n+1=0
solve
3n-2=0
3n=2
n=2/3
4n+1=0
4n=-1
n=-1/4
n=2/3 and/or -1/4
Answer:
-1.2
Step-by-step explanation:
(-1.5) * .8 = -1.2
Nicole used only a fraction of her ribbon to wrap the present
the length of ribbon she used is 6 feeet
so lets name the length of the ribbon she had originally as X
the fraction of X she used was - 3/8 of X
so we can write the following equation
when of function is used we multiply
3X = 6*8
3X = 48
X = 16
therefore length of the original ribbon piece Nicole had was 16 feet
