Write and solve an equation to answer the following question. The Smith family rented a recreational vehicle for a seven-day vacation. The cost to rent the recreational vehicle was $560 plus $0.50 per mile. How many miles were driven if the total cost was $1350? a. 790 mi
b. 1580 mi
c. 395 mi
d. 3820 mi

1580 miles

Step-by-step explanation:

We can represent the total cost for the rental with the equation d=560+0.5m where d is the cost and m is the miles driven. We know this equation works as  560 is the fixed cost, and it costs $0.5 per mile, and in math, "per" means multiplication.

Now we can solve for m as we know that d=1350 in this case.

Solving we get:

1350=560+0.5m

790=0.5m

1580=m

Thus, they drove 1580 miles.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
