Answer: the system of equations are
x + y = 22
x + 1.5y = 30
Step-by-step explanation:
Let x represent the number of math problems that Olivia solved.
Let y represent the number of pages that Olivia read.
Olivia completed a total of 22 math problems and pages of reading. This means that
x + y = 22- - - - - - - - - - - - - - -1
Olivia can solve each math problem in 1 minute and she can read each page in 1.5 minutes. Olivia completed a total of 22 math problems and pages of reading in 30 minutes. This means that
x + 1.5y = 30 - -- - - - - - - - - -2
Answer:
2 hours and 18 minutes
Step-by-step explanation:
You cannot have an answer to this because it is not an equation
Answer:
Acceptable Range (in grams) is between 0.048 grams and 0.052 grams
Step-by-step explanation:
So, it means that the actual weight can be 0.002 grams LESS THAN or even GREATER than the idea weight.
So
0.05 + 0.002 = 0.052
and
0.05 - 0.002 = 0.048
Thus, the acceptable range will be BETWEEN 0.048 grams and 0.052 grams
