Answer:
x = -2 and y = 0
Step-by-step explanation:
5x + y = -10
4x - 7y = -8
Rearrange the first equation to equal y.
5x + y = -10
y = -10 - 5x
Replace y in the second equation with the first equation.
4x - 7y = -8
4x - 7(-10 - 5x) = -8
4x - (-70 -35x) = -8
4x + 70 + 35x = -8
Rearrange the equation to find x.
4x + 35x = -8 - 70
39x = -78
x = -2
Now that you know x, use the rearranged first equation to find y.
y = -10 - 5x
y = -10 - 5(-2)
y = -10 + 10
y = 0

Well 2+2=4+3=7+3=10+3=13. 13 should be your final answer.
Step-by-step explanation:
If these were the given choices:
A. The popcorn bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the potato chip bag assembly line.
B. The popcorn bag assembly line is closer to the specifications given because its z-score is further from the standard mean than the potato chip bag assembly line.
C. The potato chip bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the popcorn bag assembly line.
D. The potato chip bag assembly line is closer to the specifications given because its z-score is further from the standard mean <span>than the popcorn bag assembly line.
My answer is: </span>A. The popcorn bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the potato <span>chip bag assembly line.
Given:
Ave.weight of a bag of popcorn - 3.02 oz
allowable deviation - 0.02 oz
Ave. weight of a bag of potato chips - 5.03 oz
allowable deviation - 0.04 oz
Actual weight of bag of popcorn - 3.03 oz
Actual weight of bag of potato chips - 5.06 oz
The allowable deviation is very minimal in a bag of popcorn thus its z-score is nearer to the standard mean as compared to the bag of potato chips. </span>
