Solving inequalities for word problems:
twice a number plus 10 is greater than three times that number less 4. what is the number?

For this case we have to:

x: Let the variable representing the unknown number

We algebraically rewrite the given expression:

Twice a number plus 10, is represented as:

Three times that number less 4. is represented as:

Thus, the complete expression is:

Subtracting 3x from both sides of the inequality:

Subtracting 10 from both sides of the inequality:

Equal signs are added and the same sign is placed:

We multiply by -1 on both sides, taking into account that the sense of inequality changes:

The solution is given by all values of "x" less than 14.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

damm bro the struggle
