Given : Karen and Daryl work for a delivery service.Karen made 15 more deliveries than Daryl. Let d be the deliveries made by Daryl .We need to find the expression that represents the number of deliveries Karen made
Karen made 15 more deliveries than Daryl. The mathematical symbol for more than is addition or + sign .
15 more than d can be represented by 15+d.
Option B. 15 + d is the right answer.
4x - y = 18
-if you work 10hrs per week on the farm and 12 hours per week babysitting,will you meet your goal?

c. 12
d. 10
Answer:
Answer 4 : 5in by 6in
Step-by-step explanation:
15 times 1/3 is 5.
18 times 1/3 is 6.
Hope I helped!!
For the polynomial x² + 18x + 80, to represent using algebra tiles would be difficult because the number of tiles needed would be very plenty.
Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.
Algebra tiles is the use of tiles to represent variables and constants.

Answer:
Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

Answer:
first answer:-1.75
second:-15.75
third:-40.25
Step-by-step explanation:i am too lazy srry
The constant of proportionality is 1.75 inches per hour. The change in water level at 9 hours of draining is 15.75 inches, and at 23 hours of draining it is 40.25 inches.
The constant of proportionality represents the rate at which the water level is changing over time. To find the constant of proportionality, we can use the formula: constant of proportionality = change in water level / number of hours. Comparing the data in the table, we can find that when the number of hours is 2, the change in water level is 3.5. Therefore, the constant of proportionality is 3.5 / 2 = 1.75 inches per hour.
Next, to find the change in water level at 9 hours, we can multiply the number of hours by the constant of proportionality: 9 x 1.75 = 15.75 inches. Similarly, for 23 hours, the change in water level is 23 x 1.75 = 40.25 inches.
