Let the cost of one pound of candy be x and one pound of mint be y.
3x+2y=10.8 a
x+3y = 5.35 b
B*3 = 3x+9y = 16.05 b
b-a = 7y = 16.05-10.8= 5.25
y = 5.25/7 = 0.75
The cost per pound of mints is $0.75
X=90 degrees you can get the answer by adding up all the angles
That equation has no solution. There is no number that can be written in place of 'x' that makes the equation true.
I’m not sure what the first one is, but number 4 is A) y=2x+4
