Final answer:
When q=4 and b=7, the value of the expression 10 + (b-a)x5 is 25.
Step-by-step explanation:
To evaluate the expression 10 + (b-a)x5, we substitute the values of q=4 and b=7 into the expression. So, a=4 and b=7. We get:
10 + (7-4)x5
= 10 + 3x5
= 10 + 15
= 25
Therefore, when q=4 and b=7, the value of the expression 10 + (b-a)x5 is 25.
