Question

7j+5-8k when j=0.5 and k=0.25

Answer 1

Answer:

6.5

Step-by-step explanation:

To perform this kind of exercise, it is necessary to replace the value indicated in each variable each time you find the variable in the equation.

$7j+5-8k$

If j=0.5 and k=0.25, replace the value of each variable.

$7(0.5)+5-8(0.25)=$

now perform the indicated operations

$7(0.5)+5-8(0.25)=3.5+5-2=6.5$
