I answered this question just now! Did you add another question like this?
1. rule = r - 12 (number = 25)
2. rule = a + 34 (number = 43)
3. rule = s - 5 (number = 20)
4. rule = b + 16 (number = 32)
5. rule = w + 3 (number = 9)
6. rule = n + 9 (number = 42)
7. 15 - n when n = 9 would be 15 - 9, and your answer would be 6.
8. "32 more than a number d" implies add d to 32, so your answer is C. 32 + d
Answer:
I'm guessing its b, but I'm not too sure
Step-by-step explanation:
Answer:
$3
Step-by-step explanation:
The money shared by Ben and Carol was split ...
... Ben : Carol = 1 : 3
The difference of these ratio numbers is 2, and the difference in amount received is $6. Thus, each ratio unit must stand for $6/2 = $3.
... Ben received 1×$3 = $3
_____
<em>The Rest of the Story</em>
Carol received 3×$3 = $9. Together, Ben and Carol received $3 + 9 = $12, which is 4/5 of the total amount. Then the 1/5 of the total amount that Alice received is
... (1/5)×$12/(4/5) = (1/4)×$12 = $3.
The $15 of money was split ...
... Alice : Ben : Carol = $3 : $3 : $9
Answer:
$6.34
Step-by-step explanation:
15.86 / 2.5 = 6.34
$6.34
The mistake is in step 3:
I: −2m =−12 − 2n
II: 2m = 8 + 8n
the student set both right sides of the equations equal (−12 − 2n = 8 + 8n), but the left sides aren't equal: first equation has -2m, second has +2m so the signs of one of the equations must be inverted first
