Answer:
Jamal hiked = 44/3 miles
Step-by-step explanation:
Mixed numbers are given in this question which can be changed into fractions by multiplying the denominator by quotient and adding numerator to it.
Given that:
Length of first trail: 5 1/3 = (3*5 + 1)/3 = 16/3 miles
According to given condition:
Length of second trail: 1 3/4 * 16/3 = (4*1+3)/4 * 16/3 = 7/4*16/3
By simplifying:
Length of second trail = 28/3 miles
So the total miles Jamal hiked = 16/3 + 28/3
Jamal hiked = 44/3 miles

8000-4.989 so when you see the word less than it means that you have to subtract and more than you have to add so the answer for this question will be 7,995.011
Let
x---------> represents Martin's sister's age
y--------> represents Martin's age
we know that
--------> equation 
--------> equation 
Substitute equation in equation
![x+[x-6]\leq 22\\2x\leq 22+6\\ x\leq 14](https://tex.z-dn.net/?f=%20x%2B%5Bx-6%5D%5Cleq%2022%5C%5C2x%5Cleq%2022%2B6%5C%5C%20x%5Cleq%2014)
therefore
<u>the answer is</u>
Part a) An inequality that can be used to represent this situation is
![x+[x-6]\leq 22](https://tex.z-dn.net/?f=%20x%2B%5Bx-6%5D%5Cleq%2022%20)
or 
Part b) the oldest age Martin's sister can be is 
years old
Answer:
3) x^2-yz/z^2
x = -3, y = 5 and z = -2 plug in these values
-3^2 -5(-2) /-2^2
= -1/4
decimal form: -0.25
4) x^2+y^2+z^2/xyz
x = -3, y = 5 and z = -2 plug in these values
-3^2+5^2+-2^2/-3*5*-2
= 2/5
decimal form: 0.4
5) x+y/z + y+z/x
x = -3, y = 5 and z = -2 plug in these values
(-3+5/-2)+(5+(-2)/-3)
= -2
6) 2x+y-z/x-3y+z
x = -3, y = 5 and z = -2 plug in these values
2(-3)+5-(-2)/-3-3(5)+(-2)
= -1/20
decimal form: -0.05
