Option D is correct.
75 miles is the total distance in miles to Kirk's grandmother's house
Step-by-step explanation:
Let x represents the total distance in miles to Kirk's grandmother's house.
As per the statement:
Kirk's family drove 36 miles in 50 minutes, which was 48% of the distance to his grandmother's house
⇒ Distance Kirk's family drove = 36 miles.
then;
36 = 48% of x

Multiply both sides by 100 we get;
3600 = 48x
Divide both sides by 48 we have;
75 miles = x
Therefore, the total distance in miles to Kirk's grandmother's house is 75 miles
Answer:
Step-by-step explanation:
Fraction form: x=7/12
Steps:
64^4x-3
2^6(4x-3)=2^-4
6(4x-3)=-4
4x-3=-2/3
4x=7/3
X=7/12
