The answer would be 100 punces
X=Lucy´s money
y=Edy´s money
we can suggest this system of equations:
x=y+(35/100)y ⇒x=135y/100
x+y=206.8
solve by substitution method.
(135y/100)+y=206.8
Least common multiple=100
135y+100y=20680
235y=20680
y=20680/235=88
then:
x=135y/100=135(88)/100=118.8
Answer:
Lucy´s money=$118.8
Edy´s money=$88
To check:
Together, the girls have saved a total of $118.8+$88=$206.8
Lucy´s savings account has: $88+(35/100)$88=$118.8, 35% more monty than Edy´s. account. .
1. i showed work
4x + 2y = -6- move constant left. change sign
4x + 2y + 6 = 0- divide both sides by 2
2x + y + 3 = 0 <— answer
2. i showed work
2x - y = 8- move constant to the left
2x-y-8=8-8- sum of two opposites equal 0
2x-y-8=0 <— answer
Answer: = 36288
Step-by-step explanation:
(14)(32)(81)
=(448)(81)
=36288
not sure what you were asking for but i hope this helps
