Answer:

Steven is 15 and one half years old now

Step-by-step explanation:

Linear equations

Sometimes we need to know the value of a variable in a given equation and that variable is given as a polynomial of degree 1. Solving for that variable means isolating it and replacing the other known values

Steven was 7 years old eight and one-half years ago. If we call x as the actual age of Steven, his age eight and one-half years ago was

$x-8\frac{1}{2}$

We know he was 7 years old then, so

$x-8\frac{1}{2}=7$

We need to know his actual age, so let's solve for x, adding $8\frac{1}{2}$ to each side of the equation

$x-8\frac{1}{2}+8\frac{1}{2}=7+8\frac{1}{2}$

Simplifying

$x=15\frac{1}{2}$

5. 3x-X-7=3 6.3x-3-X=3 7. -1 - 2x +3x=5 8. 3x - 22 - X=6 9. 2x+3x-10=10

Marta_Voda [28]

** 3x - x -7 = 3

2x = 10

x = 5

** 6. 3x - 3 -x = 3

18x - 3 - x = 3

17x = 6

x = $\frac{6}{17}$

** 7. -1 - 2x + 3x = 5

-7 - 2x + 3x = 5

-7 + x = 5

x = 12

** 8. 3x - 22 - x = 6

24x - 22 - x = 6

23x = 28

x = $\frac{28}{23}$

** 9. 2x + 3x -10 = 10

18x + 3x - 10 = 10

21x = 20

x = $\frac{20}{21}$

Solve the expressions on the left when x=5 3x-10 x^2-15 5x-21 x+10-8

Nitella [24]

Answer:

Step-by-step explanation:

Apply the value of x into the expressions:

3(5) - 10 = 15 - 10

= 5

5² - 15 = 25 - 15

= 10

5(5) - 21 = 25 - 21

= 4

5 + 10 - 8 = 15 - 8

= 7

Find the simplest form of the general term for the sequence 11, 15, 19, 23, .

sveta [45]

The general term of an arithmetic sequence is
an = a1 +(n-1)d
Your sequence has first term a1 = 11 and common difference d = 4. Then the general term is
an = 11 + (n-1)*4

The simplest form of the general term is
an = 7 + 4n
