Answer:
The child has 6 dimes and 5 quarters.
Step-by-step explanation:
Let q and d represent the number of quarters and of dimes respectively.
Then q + d = 11 (Equation A), and ($0.25/quarter)q + ($0.10/dime)d = $1.85 (Equation B).
Multiply the 2nd equation by 100 to remove the decimal fractions:
25q + 10d = 185 (Equation C)
Now multiply the 1st equation by -10 to obtain -10q - 10d = -110 (Equation D), and combine this result with Equation C:
-10q - 10d = -110
25q + 10d = 185
--------------------------
15q = 75, and so q = 75/15 = 5.
According to Equation A, q + d = 11. Replacing q with 5, we get:
5 + d = 11, and so d = 6.
The child has 6 dimes and 5 quarters.
we are given
highest exponent is 3
degree is the highest exponent
so, degree is 3
Answer:
D) 360
Step-by-step explanation:
The data Kyle collected is (0, 0), (1, 12), and (2, 24), where x represents days and y represents likes.
We can write a linear function to model this situation.
This will be of the form

because it passes through the origin , where m is the slope.
The slope is

Hence the equation is

To find the number of likes on the 30th day, we put x=30 into the equation to get:

The correct choice is D
