The formula to find two consecutive odd integers is x + (x+2)
5(x+2) = 1 + 8(x)
5x + 10= 1 + 8x
10= 1 + 3x
9=3x
x = 3
Answer : the larger integer is 5(3+2) which is 25
Nana's age: 10 years
Step-by-step explanation:
Here we call:
J = Jennifer's age
L = Laurel's age
N = Nana's age
We have the following information:
- Jennifer is twice as old as laurel, so
J = 2L (1)
- Laurel is 4 years younger than Nana, so
L = N - 4 (2)
- Nana is 2 years younger than Jennifer, so
N = J -2 (3)
Substituting (2) into (1),
J = 2(N-4) = 2N - 8
And substituting this into (3) and solving for J, we find Nana's age:
N = (2N-8) - 2
N = 2N - 10
N = 10
Which means that Jennifer's age is:
J = N + 2 = 12
And Laurel's age is
L = J/2 = 6

Answer:
x = 20
Step-by-step explanation:
Here, we want to get the value of x
To get the value of x, we need to know the kind of relationship that exists between the two given angles
Both angles lie on a straight line and that means they are supplementary
What this mean is that they add up to 180
(5x-7) + (3x + 27) = 180
5x -7 + 3x + 27 = 180
5x + 3x -7 + 27 = 180
8x + 20 = 180
8x = 180-20
8x = 160
x = 160/8
x = 20
