The solution that makes both equations true is 'a', or (2,0), because if you substitute the 2 with the x and the 0 with the y, and solve both equations, you get the same answer. Also, you could try a graphing software, like desmos.
0=-2(2)+4
-4+4
0=0
0=(2)-2
0=0
2.0 times 60= 120 feet per minute
120 times 90= 10,800.0 feet
10,800 times 0.000189= about 2.0 miles
Hello!
You divide how long the line is by the amount of segments
9 / 10 = 0.9
The answer is 0.9 inches long
Hope this helps!
Let L and S represent the weights of large and small boxes, respectively. The problem statement gives rise to two equations:
.. 7L +9S = 273
.. 5L +3S = 141
You can solve these equations various ways. Using "elimination", we can multiply the second equation by 3 and subtract the first equation.
.. 3(5L +3S) -(7L +9S) = 3(141) -(273)
.. 8L = 150
.. L = 150/8 = 18.75
Then we can substitute into either equation to find S. Let's use the second one.
.. 5*18.75 +3S = 141
.. S = (141 -93.75)/3 = 15.75
A large box weighs 18.75 kg; a small box weighs 15.75 kg.
The correct answer of 16/38 simplified is 8/19
