Cars and truckd are the most popular vechicles last year the nunber of cars sild was 39,000 more then three times the number of trucks sold there were 216,000 cars sold last year . Write an equation that can be used to find the number of trucks t sold last year

The equation that can be used to find the number of trucks t sold last year is: t=(c-39,000)/3.

Step-by-step explanation:

From the information given, you know that the number of cars sold was 39,000 more than three times the number of trucks, which could be expressed as:

c=39,000+3t, where:

c is the number of cars sold and t is the number of trucks sold

Also, you know from the information provided that there were 216,000 cars sold last year, so you can solve the equation for t and replace the value of c to find the number of trucks sold last year:

c-39,000=3t

t=(c-39,000)/3

t=(216,000-39,000)/3

t=59,000

According to this, the equation that can be used to find the number of trucks t sold last year is: t=(c-39,000)/3.

First set are parallel, second are perpendicular, third are perpendicular, fourth are neither.

Step-by-step explanation:

1. Same slope (6/5) = parallel

2. Reciprocal (flipped) slope, opposite signs

3. Reciprocal (flipped) slope, opposite signs

4. Neither, the slopes aren't the same or flipped

When you flip the slopes (3/4 becomes 4/3) and change a sign, the lines will always be perpendicular.
