26-$15.50=10.5
10.5/1.5=7
he can ride 7 rides in one day
Answer:
2 x 7
Step-by-step explanation:
a * b = 14
2a + 2b = 18
(a * b)/b = 14/b Dividing both sides by b
a = 14/b
Substitute a in the perimeter equation
2(14/b) + 2b = 18
28/b + 2b = 18
2b - 18 + 28/b = 0
Multiply both sides by b
2b^2 - 18b + 28 = 0
Divide both sides by two
b^2 - 9b + 14 = 0
The Factors of 14 include -2 and -7 which add up to -9
(b - 2) * (b - 7) = 0
This has two answers because b can be either the side that is 2 long or 7 long, so there's no need to go back and solve for a.

Distance between points (9, -4) and (-3, 5) is 15
Answer:
4 and 5
Step-by-step explanation:
We know that.
√16 < √21 <√25
⇒4 < √21 < 5
Hence √
21 lies between 4 and 5
