Find the value of x so that the function has the given value f(×)=×; f(×)=-24

The value of x is - 24.

Step-by-step explanation:

Given that , the function f(x) as

                       f(x) = x

We need to find out the value of x if f(x) = -24

According to given statement,  the value of function is equal to the value of x that satisfy the function.  So from the given data,

                     f(x) = - 24

But we know that f(x) = x, so  the value of 'x' must be as below,

                              x = - 24

Hence, the value of x is - 24.

1.125 =x

Step-by-step explanation:

We can use ratios to find the  time

We want to find the time needed to finish

1 - 2/5 = 3/5  We need the time for 3/5 of the project

3/4 hours        x hours

=

2/5 project       3/5 project

Using cross projects

3/4 * 3/5 = 2/5 * x

9/20 = 2/5x

Multiply each side by 5/2

9/20 * 5/2 = x

9/8 = x

1 1/8 =x

1.125 =x
