About half of what they did
pacey = x
alex = 2x
paul = 3x
x + 2x + 3x = 342
6x =342
x = 342 / 6
x = 57
Pacey's fish = 57 pounds
Alex's fish = 57*2 = 114 pounds
Pauls fish = 57*3 = 171 pounds
Answer=9
To solve this, we just have to find a number that, when added to -4, make a total of 5, and when multiplied by -4 make a total of -36.
x+-4=5
x*-4=-36
9 fits the parameters for both of these
9+-4=9
9-4=5
5=5
9*-4=36
36=36
Answer:
b=(13/4, -27/4, -4)
Step-by-step explanation:
A.x=b
x=(a, b, c)
a - b + 2c = 2
3a + b + 0 = 3
0 + 0 + c = -4
solving this system
c=-4
a-b=10, 3a+b=3
a=10+b, 3(10+b)+b=3
b=-27/4
a=10-27/4
a=13/4
