3=4m+ b
-1=3m+b
m=4
plug in to either equation,
3=16+ b
b=-13
Thus, C would be the answer.
1. A 1.0 minute
Range can be calculated by subtracting 3.0 mins - 2.0 mins = 1.0 minute.
2. D. 4
Joel was faster than Gunner in meets 1, 2, 3 and 4.
3. B. 1.75 minutes
Gunner has consistent improvement at intervals of 0.25 minutes per meet. Subtracting 2.0 mins by 0.25 mins we get 1.75 minutes.
Answer:
9
Step-by-step explanation:
The first sentence of the problem can be interpreted two ways. The way that makes the second sentence work out correctly is ...
'a larger number is 5 less than 3 times a smaller number'
Using x for the smaller number, the two equations that can be written are ...
Adding 4 times the first equation to the second, we get ...
4(3x -y) + (x +4y) = 4(5) +(97)
13x = 117 . . . . . simplify
x = 9 . . . . . . . . divide by 13
The smaller number is 9.
Probably C. 30 Hope this helps I might wrong sometimes
