I’m guessing 108. 45 divided by 5 is 9, so 9 times 12 is 108.
<span>This is a right triangle problem. c^2 = a^2 + b^2
Let b = 7 mi (Rosa's distance from home)
Let a = the east leg (Juan's distance from home
(a+1) = c (hypotenuse, distance between them)
(a+1)^2 = a^2 + 7^2
FOIL (a+1)(a+1)
a^2 + 2a + 1 = a^2 + 49
Combine like terms
a^2 - a^2 + 2a = 49 - 1
2a = 48
a =
<span>a = 24 mi, Juan's distance from home

Answer:
5
Step-by-step explanation:
X + 2y = 13
Since x = 3
3 + 2y = 13
2y = 13 - 3
2y = 10
Divide both sides by 2
Y = 5
