Answer:
-5/2+-2
Step-by-step explanation:
The total amount that Sara spent for her meals during the first week is,
$11.52 + $6.48 + $5.99 + $14.00 + $9.50 = $47.49
With an average of $9.498
During the second week, she spent $4 more making her total equal to $51.49. The average is equal to $10.298. The increase in the mean is equal to,
increase in mean = $10.298 - $9.498 = $0.8<span>Comments</span>
Hey there!
2/3 = a/30
First: you have to CROSS MULTIPLY the given numbers
2(30) = 3(a)
2(30) = 60
3(a) = 3a
New EQUATION: 3a = 60
Second: DIVIDE 3 to BOTH SIDES
3a/3 = 60/3
CANCEL out: 3/3 because that gives you 1
KEEP: 60/3 because that helps you solve for your a-value
60/3 = a
60/3 = 20
Therefore, your answer is: a = 20
Good luck on your assignment and enjoy your day!
