First one has initial height of 12 cm and on that inicial height we add 2cm each month which can be written as 2m + 12
Second one has initial height of 10 cm and grows 3cm per month which can be written as 3m + 10
Now we just have to find those expressions in offered equations to find answer.
We can see that system of equations is:
H(m) = 12 + 2m
H(m) = 10 + 3m
or third pair.
Answer:
The answer is 5.
Since he has 3 part chocolate all he has 18 cups left. You can keep adding 3 till you get 18 and how many ever groups you have with 3 (which is 5 groups) is the answer.
Answer:
B. h = 7.4 inches
Step-by-step explanation:
height of the laptop screen = h
d = 12.1 in.
w = 9.6 in.
We are given the formula,
d = √(w² + h²)
Plug in the values and solve for h
12.1 = √(9.6² + h²)
Square both sides
12.1² = 9.6² + h²
146.41 = 92.16 + h²
146.41 - 92.16 = h²
54.25 = h²
√54.25 = h
7.4 = h (nearest tenth)
h = 7.4 inches
