Answer:
Minimum - 8.1 inches
Maximum - 8.35 inches
Step-by-step explanation:
The specifications for manufacturing a steel rod stipulate that the length must be 8.225 ± 0.125 inches.
This means that the minimum length must not be 0.125 inches less than 8.225 inches and the maximum length must not be 0.125 inches greater than 8.225 inches.
The minimum length is therefore:
8.225 - 0.125 = 8.1 inches
The maximum length is therefore:
8.225 + 0.125 = 8.35 inches

Answer:
C
Step-by-step explanation:
my teacher tells us that that answer is the most inportant in math in any grade
The correct answers are (-3, 4) (-6, 6) (0, 2)
Let sandwiches =x and drink =y.
2x+1y=7.50
5x+2y=18
Then solve simultaneously.
Sandwiches, x= 3
Drink, y= 1.5
