Answer: D
Step-by-step explanation:
3 x 4 = 12
add the i onto the end
The easiest way to find answers for questions like these is to convert them to improper fractions, solve, and then convert them back to mixed numbers (if the question required it). When we convert these to improper fractions, we have 7/4 and 19/8. We can then find the least common denominator of the 2 so that we can solve. The least common denominator is 8, and since we are multiplying the 4 by 2 to get it there, we must also multiply the 7 by 2. Now we have 19/8-14/8. At this point, we can use simple subtraction to subtract the numerators and get 5/8.
To summarize, Cameron used 5/8 more acid in the second experiment.
Answer:
The function shown by the graph is ⇒ 1st answer
Step-by-step explanation:
<em>To find the function chose two points from the graph and substitute their x-coordinates in each function, the right function we give you the corresponding y-coordinates</em>
From the figure:
∵ The graph passes through points (2 , 1) and (3 , 1.5)
∵
∵ x = 2
∴
∴
∴
∴ f(2) = 1 ⇒ same value of y-coordinate
∵ x = 3
∴
∴
∴
∴ f(3) = 1.5 ⇒ same value of y-coordinate
∴ The function shown by the graph is
Answer:
Step-by-step explanation:
Add 81 to both sides:
Answer:
Its answer is 20 because there is no x with 20 number so it willl be same
