Answer:they will drive 500 miles each day.
Step-by-step explanation:
The Thompson family is traveling 1,500 miles to visit relatives. They plan to drive the same distance each day.
Let x represent the distance that they travel each day. If the Thompsons make the trip in 3 days, it means that the total distance that they travelled in 3 days would be
3 × x = 3x miles
Therefore , the distance that they will drive each day would be
3x = 1500
Dividing both sides of the equation by 3, it becomes
3x/3 = 1500/3
x = 500 miles
Answer:
x = +2, x = -2
Step-by-step explanation:
The equation to solve in this problem is
The first step we do is to subtract 35 on both sides of the equation, so we get:
Now we simplify the equation by dividing both terms by 10:
Now we observe that the term on the left is the difference between two squares, so it can be rewritten using the property:
Where here,
a = x
b = 2
So we can rewrite the equation as:
And this equation is zero when either one of the two factors is zero, so the two solutions are:
