Y = 3x2 + -27
Reorder the terms:
y = -27 + 3x2
Solving
y = -27 + 3x2
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = -27 + 3x2
So if a number is 5 or greater you round up but if the number is 4 or less you round down so the number 6 is above five so you would round the 6 to 10 therefore making it 7.8 instead of 7.76
Answer:
Step-by-step explanation:
6 times 7 =42
5 times 7 =45
42 + 45 = 87
Answer:
Step-by-step explanation:
We multiply 4/5 times 3/1 to find how many miles the penguins swam in one hour.
4 x 3/5 x 1
12/5
The penguins swam 12/5, or 2 and 2/5 miles in one hour.
Table:
Miles 4/5 12/5
Hours 1/3 1
1 x 147 = 147
3 x 49 = 147
7 x 21 = 147
21 x 7 = 147
49 x 3 = 147
147 x 1 = 147
-1 + 29 = 28
-2 + 30 = 28
-3 + 31 = 28
1.25 + 26.75 = 28
2.50 + 25.5 = 28
3.75 + 24.25 = 28
1 + 27 = 28
2 + 26 = 28
3 + 25 = 28
12 + 16 = 28
13 + 15 = 28
14 + 14 = 28
