Answer:
Step-by-step explanation:
Step 1:
Step 2:
Then multiply both by 1000
It cant be simplifyed further so its in simplest form
<span>2m/7+3m/14=1
We simplify the equation to the form, which is simple to understand
<span>2m/7+3m/14=1
Simplifying:
<span> + 0.285714285714m+3m/14=1
Simplifying:
<span> + 0.285714285714m + 0.214285714286m=1
We move all terms containing m to the left and all other terms to the right.
<span> + 0.285714285714m + 0.214285714286m=+1
We simplify left and right side of the equation.
<span> + 0.5m=+1
We divide both sides of the equation by 0.5 to get m.
<span>m=2

You have the correct answer. It is choice B) -1/4
=======================================================
Explanation:
This is because we're adding -1/4 to each term to get the next one. In other words, we're subtracting 1/4 from each term to get the next one.
- term2 = term1+(d) = 1/2 + (-1/4) = 1/2 - 1/4 = 2/4 - 1/4 = 1/4
- term3 = term2+(d) = 1/4 + (-1/4) = 1/4 - 1/4 = 0
- term4 = term3+(d) = 0 + (-1/4) = 0 - 1/4 = -1/4
- term5 = term4+(d) = -1/4 + (-1/4) = -2/4 = -1/2
and so on.
----------
To find the common difference, all we have to do is subtract any term from its previous one.
For example:
d = (term2) - (term1)
d = (1/4) - (1/2)
d = (1/4) - (2/4)
d = (1-2)/4
d = -1/4
The order of subtraction matters, so we cannot say d = term1-term2.
Answer:
Step one identify the two points on the line in the graph
Example: (0,2) ( 2,1)
Step two calculate the vertical change from one point to the next
Step three write the ratio vertical change over horizontal change
Example (-1/2 )
