Answer:
8:15 am
Step-by-step explanation:
Count back from 9:05 50 minutes. I did it in parts.
First, I went back 5 minutes:
9:05 am 50 minutes elapsed
9:00 am 45 minutes elapsed
Then I went back the rest of the 45 minutes
9:00 am 45 minutes elapsed
8:15 am 0 minutes elapsed
(7x+2)(20-3x/4) = 140x + 40 - 21x²/4 - 3x/2 = -21/4 x² + 138 1/2 x + 40
this is one of those multiplications that doesn't make the result look any simpler...
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
Answer:
81-25k²
Step-by-step explanation:
We need to write the expression for "The quantity 81 minus 5k, squared".
Square of any number x is given by x².
Square of 5k is given by : (5k)²= 5²×k²=25k²
Now subtract 25k² from 81.
It means we get : 81-25k². It is required expression.
