Algebraic Woru
mafiozo [28]

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

3y+y+2y=612\\6y=612

Dividing both sides by 6

\frac{6y}{6}=\frac{612}{6}\\y=102

Putting in Eqn 1;

x=3(102)\\x=306

Kyle has $306 in his account.

The right answer is Option D.

can someone help me anyone please Giselle works as a carpenter and as a blacksmith.She earns \$20$20dollar sign, 20 per hour as
Artemon [7]
Let she work for x hours as carpenter !
so earned money = 20x

and for blacksmith she must work for 30-x hours 


so earned money = (30-x) ×25

so putting in eqn;

20x+25(30-x) = 690 
so, x= 60/5 = 12 

so she works for carpenter for 12 hrs and 30-12= 18 hrs for blacksmith
