Equation: 15 + 6t = 81
Work: 15 + 6t = 81
-15 -15
6t = 66
t = 11
I think I might hav the answer... but is “and” supposed to represent “plus” or is it a separate question?
Answer:
The answer is that x = 0 and y = -6. While this is not any of your options, the work below proves that it is correct.
In order to find these values, we can use elimination. To do so, we multiply the first equation by 5 and then add the equations together.
125x - 5y = 30
-2x + 5y = -30
------------------
123x = 0
x = 0
Now that we have this value, we can plug the value into one of the originals and find y.
25x - y = 6
25(0) - y = 6
-y = 6
y = -6
Answer:
129 1/6 feet
Step-by-step explanation:
Formula for area is L*W
1. convert the mixed numbers to improper fractions
12 1/2 feet = 25/2
10 1/3 feet = 31/3
2. multiply numerator by numerator (25*31 = 775
3. multiply denominator by denominator (2*3=6
4. convert improper fraction 775/6 into a mixed number by dividing 775 by 6.
5. 775/6 = 129 r. 1 or 129 and 1/6
