Answer:
36
Step-by-step explanation:
Two Consecutive Odd Numbers: D, D+2
(D+2) + 2D = 4D - 27
D + 2 + 2D = 4D - 27
3D + 2 = 4D - 27
3D + 29 = 4D
29 = D
Two Consecutive Odd Numbers are 29, 31
Check. . 31 + 2(29) = 4(29) - 27
..................31 + 58 = 116 - 27
.................89 = 89 ..... CORRECT!
Answer:
Eli's age = 42 years
Step-by-step explanation:
Let x be Eli's age and y be Cecil's age
So,
According to the statement given
x+y=60 eqn 1
Eli's age 6 years ago = x-6
Cecil's age 6 years ago = y-6
So according to the given statement
x-6 = 3(y-6)
x-6 = 3y - 18
x-3y = -18+6
x-3y= -12 eqn 2
Subtracting eqn 2 from eqn 1
x+y - (x-3y) = 60 - (-12)
x+y-x+3y = 60+12
4y = 72
y = 18
Cecil's age = 18 years
Putting y = 18 in eqn 1
x+18=60
x = 60-18
x = 42
Eli's age = 42 years ..
The answer is 36, 38, 40, 42
The numbers are:
(1) x is the first even number
(2) x + 2 is the first <span>consecutive even number
(3) x + 2 + 2 </span>is the second consecutive even number
(4) x + 2 + 2 + 2 is the third consecutive even number
x + x + 2 + x + 2 + 2 + x + 2 + 2 + 2 = 156
x + x + x + x + 2 + 2 + 2 + 2 + 2 + 2 = 156
4x + 12 = 156
4x = 156 - 12
4x = 144
x = 144 / 4
x = 36
The numbers are:
(1) x is the first even number: x = 36
(2) x + 2 is the first consecutive even number: x = 36 + 2 = 38
(3) x + 2 + 2 is the second consecutive even number: x = 36 + 2 + 2 = 40
(4) x + 2 + 2 + 2 is the third consecutive even number: x = 36 + 2 + 2 + 2 = 42
