-10.22, -7.89, -5.23, +34.98, +51.02, +51.22 because the closer a number is to 0 the smaller it is.
Answer:
(-5,-14)
Step-by-step explanation:
To find the solution of the system of two equations

equate right sides of these two equations:

Rewrite terms with x into the left side and without x into the right side:
![4x-2x=-4-6\\ \\2x=-10\ [\text{divide by 2}]\\ \\x=-5](https://tex.z-dn.net/?f=4x-2x%3D-4-6%5C%5C%20%5C%5C2x%3D-10%5C%20%5B%5Ctext%7Bdivide%20by%202%7D%5D%5C%5C%20%5C%5Cx%3D-5)
Substitute x=-5 into the first equation:

The solution is (-5,-14)
50 minutes= 5/6 hr
(1 3/4 miles)/ (5/6 hr)= 2.1 miles/hr
Hope this would help~
Answer: 554
Step-by-step explanation:
If prior population proportion is known, then the formula to find the sample size is given by :-

As per given description, we have
p= 0.1
E=0.025
Critical z-value for 95% confidence : 
Then,

Hence, the minimum sample size required = 554.
