Summing to zero means the two numbers are additive inverses, i.e. negatives of each other. We choose the pair of negations:
Answer: -3, 3
Answer:
1. Going to the close store is cheaper.
Step-by-step explanation:
The difference in the prices of chicken is 3.19 -2.89 = 0.30 per pound, so for 5 pounds of chicken, the far store offers a price that totals 5×$0.30 = $1.50 less.
The difference in travel distances is 8.4 -2.4 = 6 miles, so the total round-trip distance difference is 12 miles. The cost of gas is ...
($3.81 /gal)/(23 mi/gal) = $0.1656 /mi
so the cost of gas for the 12-mile longer trip would be
12×$0.1656 ≈ $1.99
Traveling to the far store, you would spend $1.99 more on gas to save $1.50 on the price of chicken. Going to the close store is cheaper.
Ratio given 1:2
Let's suppose the ratio as x : 2x
Adding the ratio = 3x
![\frac{x}{3x} \times 120 \\ =40](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B3x%7D%20%20%5Ctimes%20120%20%5C%5C%20%3D40)
![\frac{2x}{3x} \times 120 \\= 80](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%7D%7B3x%7D%20%20%5Ctimes%20120%20%5C%5C%3D%2080)
40 and 80 are in the ratio 1:2 of 120.

Answer:
Mean: 67.7 (rounded to the nearest tenth)
Median: 52.2
Mode: 55
Step-by-step explanation:
To find the the mean is to take all the numbers, all them together and divide by how many numbers there is. 50+55+42+38+163+55+61= 564 then divided by 6 is 67.7
to find the median is to put all the numbers in order, (I prefer to go increasing order) and then find the middle number. If there is no middle number you take the two numbers around it and subtract them from one n another.
Mode is to find the most common number. Whichever number repeats itself
