Answer:
If b is 3, x=-1
Step-by-step explanation:
-2(3x-5)=16
use distributive property
-6x+10=16
take 10 away from both sides
-6x=6
divide both sides by -6
x=-1
So when you change the mixed numbers into improper fractions, they become 85/4 and 74/4. Your new problem is 85/4-74/4. Basically 85-74. That equals 9. So the improper fraction answer is 9/4. We now make that back into a mixed number, creating 2 1/4, or A.
Answer:
The correct answer is option C. y = 31x + 154.
Step-by-step explanation:
Since x represents the days and she learns 31 words per day you would need to multiply 31 and the number of days (x).
This would look like 31x.
We also know she already knew 154 from the beginning which means we just have to add 154.
This leaves us with the equation y=31x + 154.
Hope this helps!
