Creflo is 6 years older than Dean.
Raheem is twice as old as Creflo.
The sum of their ages is 34.
Work out the ratio of Dean's age to Creflo's age to Raheem's age.
Answers
R = 2C
D + C + R = 34
R = 2 (D+6)
R = 2D + 12
D + (D + 6) + (2D + 12) = 34
Add like terms.
4D + 18 = 34
4D = 34 - 18
4D = 16
D = 4
C = D + 6
C = 4 + 6
C = 10
R = 2C
R = 2(10)
R = 20

quick question is this area or perimeter?
Answer:
2 and 3
Step-by-step explanation:
to be similar, there must have been the same scaling factor applied for length and width.
when going from 2 to 3 the width changes from 5 to 7, that is a changing factor of 7/5 = 1.4
and the length changes by the same factor :
6.5 × 7/5 = 1.3 × 7 = 9.1

[tex]x = \sqrt{146.41} [/tex]
[tex]x = 12.1[/tex]
_____________________________________________
Perimeter = 4x

[tex]p = 48.4[/tex]
The Perimeter of Square is 48.4 m.
What is Area and Perimeter of Square?The Area of square is the product of the side.
Area of Square = side x side
and, The Perimeter of Square is 4 times the side of square
Perimeter of Square = 4 x side
Given:
Area of Square = 146.41 m²
Now, Area of Square = side x side
Area of Square = side²
side² = 146.41 m²
side = √146.41 m²
side = 12.1 m
Now, the Perimeter of Square = 4 x side
= 4 x 12.1
= 48.4 m.

Depending on simplified form asked.
Step-by-step explanation:
6x +8 =28
subtract 8 from both sides
6x = 20
divide by 6
x=20 /6
x= 10/3 or x =3.334
if you like my answer, please mark me brainliest !! thanks !! <3
2(3x + 4) =-28
divide both sides by 2
2(3x+4)/2 = -28/2

3x + 4 - 4 = -14 - 4
after subtracting its 3x = -18
divide 3 from both sides
