Answer: See below
Explanation:
1a.
-4 • 1 = 8(y-5)
-4 = 8y - 40
-8y = -40 + 4
-8y = -36
Y = -36/-8
Y = 9/2
1b.
3c - 6 = -6 + 9(c+9)
3c - 6 = -6 + 9c + 81
3c - 9c = 75 + 6
-6c = 81
C = 81/-6
C = 27/-2
2a.
6(p-2) = -2 + 3
6p - 12 = 1
6p = 13
P = 13/6
2b.
3x - 4 = -3 + 4(x - 3)
3x - 4 = -3 + 4x - 12
3x - 4x = -15 + 4
-x = -11
X = 11
X+y=0
x = -y
-y-y+2=0
-2y=-2
y=1
x+1=0
x=-1
(-1,1)
So,
If this was mental math, I would round 1.87 to the nearest pound and 2.46 to the nearest half pound, making the following addition problem:
2 + 2.5 = 4.5
Because 1.87 is closer to 2 than to 1.5 or 1, and 2.46 is sooo close to 2.5.
So I would say about 4.5 pounds of meat.
But if you're rounding to the nearest pound for both, then you have this equation:
2 + 2 = 4
Because in 1.87, 8 is greater than or equal to 5, and in 2.46, 4 is less than or equal to 5.
So in that case, it would be about 4 pounds of meat.
