3 1/8 + 1 2/5 = 4 21/40 because the least common denominator is 40. So 5x8=40 and 2x8=16. Then 8x5=40 and 1x5=5. Next you add the numerators and get 21/40. And last but not least you add the whole numbers to get a final answer of 4 21/40
Answer:
h(t) = 12 inches + (1 inch/week)t; continuous
Step-by-step explanation:
This situation can be described with a linear function. The initial value of the plant height is 12 inches, and the weekly growth is 1 inch/week.
Thus, if h(t) represents the plant height at the end of the t-th week,
h(t) = 12 inches + (1 inch/week)t
The slope is 1 inch/week, and is continuous, since plan growth is continuous.
X = y + 7
49 = x + y
49 = y + y + 7
49 = 2y + 7
42 = 2y
y = 21
x = 21 + 7
You have 21 dimes and 28 quarters
