Rosa's because about 33% of her floor is covered in toys, while Serena's floor is only covered with 25% toys.
The coordinates of trapezoid vertices are:
- J(-7,-2);
- K(-4,-2);
- L(-2,-5);
- M(-9,-5).
The translation rule is
(x,y)→(x-2,y+8).
Then the image trapezoid vertices are:
- J'(-7-2,-2+8) that is J'(-9,6);
- K'(-4-2,-2+8) that is K'(-6,6);
- L'(-2-2,-5+8) that is L'(-4,3);
- M'(-9-2,-5+8) that is M'(-11,3)
we have the equation
2(x-4)=6x+4
solve for x
Apply distributive property left side
2x-2(4)=6x+4
2x-8=6x+4
Group terms
6x-2x=-8-4
combine like terms
4x=-12
divide by 4 both sides
x=-12/4
<h2>x=-3</h2>
Answer:
a) Micheal's present age = 8 years old
b) The sum of their ages in 6 years time = 63 years.
Step-by-step explanation:
From the above question, we know that
Rui feng is 3 years old
We are told that
• Michael is 5 years old than Rui feng
Micheal's present age is calculated as:
= 5 + Rui feng's age
= 5 + 3 = 8 years
• Vishal is thrice as old as Micheal
Vishal's present age is calculated as
= 3(Micheal age)
= 3(8)
= 24 years.
The sum of their ages in six years time
= ( 3 + 6) +( 8 + 6) + ( 24 + 6)
= 18 + 15 + 30
= 63 years
Therefore, a) Micheal's present age = 8 years old
b) The sum of their ages in 6 years time = 63 years.
