For this case we have, according to the statement, the following equation:

x + y = 3

We must find 5 pairs of integers that meet the equation:

(-1,4)\\-1 + 4 = -1 + 4 = 3

(1,2)\\1 + 2 = 3

(7, -4)\\7 + (- 4) = 7-4 = 3

(3,0)\\3 + 0 = 3

(5, -2)\\5 + (- 2) = 5-2 = 3

Answer:

The pairs of integers can be:

(-1,4)\\(1,2)\\(7, -4)\\(3,0)\\(5,-2)\\

(d) A car travels at an average speed of 80 km/h. How far does it travel in: (1) 2 hours? (11) 12 minutes?​
zepelin [54]
Answer is (1) 160 km in 2 hours and
(2) 16 miles in 12 minutes.

Step by step.
80 km / 1 hour = x km /2 hours
Cross multiply =
x = 160

The second one requires a little more math. Because we are looking at how far in minutes, we change the rate of 80km in 1 hour to 80 km in 60 minutes.
80 km / 60 = x / 12
Cross multiply
12x = 960
Solve for x by dividing both sides by 12
X = 16

I did the math on a print screen to explain the cross multiply.
