13/90
so there are 90 two digit numbers.
there are a 13 two digit numbers divisible by 7. so there is a 13/90 probability of a two digit number being selected at random that’s divisible by 7
Starting equation:
92=J+L+B
To find how much money Jane has, we use the equation:
J=5+3L
To find how much money Bob has, we use the equation:
B=4L-1
Enter those equations in the problem
92=(5+3L)+L+(4L-1)
Combine like terms
92=4+8L
Subtract 4 to isolate variable
88=8L
Divide by 8 to isolate variable
11=L
Answer:
Lonnie has $11
Jane has $38
Bob has $43
side note: Lonnie is that one poor friend we all have
Answer: 
Step-by-step explanation:
Given
Ladder is 16 ft from bottom and 12 away from the base of the wall
In another case ladder is 18 ft above the ground and let say x ft away from the base of the wall
In both the cases the length of ladder remains the same
Using Pythagoras theorem, we can write

Answer:
f^-1(x) = (-1/5)x - 11/5
Step-by-step explanation:
f^-1(x) is the inverse so it must be
f^-1(x) = (-1/5)x - 11/5
