A. your equation would be 17 + 8.50X
number of additional large pizzas equation cost
1 17 + 8.50(1) $25.50
2 17 + 8.50(2) $34.00
3 17 + 8.50(3) $42.50
b. will get back to you
c. 17 + 8.50 (20) = 187 $187
d. $34 X 5 = $170 17 + 8.50 (14) = $136 170 - 136 = $34 saved
Answer:
3 km per hour
Step-by-step explanation:
You can deduct the answer instinctively since both the distance and the time of the descent are expressed in /5... so you can just get rid of the '/5' in both instances to get the result: 3 kilometers in 1 hour.
But you can also find it easily using the cross-multiplication system:
Then you multiply each side by 5 to get
3 km = 1 hour
Thus the rate of descent is of 3 km per hour.
