Answer:
1) A = -10, B = -4, distance = 6 units
2) Eqaution: 3(x+4) = 60
Tyler's age: 16 Samantha: 20
3) x < 1
Draw a number line from 1 towards left, with an open circle at x = 0
Step-by-step explanation:
1) A/2 = -5
A = -5×2 = -10
8 = -B/0.5
8×0.5 = -B
B = -4
Distance = -4 - (-10) = -4 + 10 = 6
2) S = 4 + x
3s = 60
3(4 + x) = 60
3S = 60 S = 20
4 + x = 20 x = 16
3) x/2 + ¼ < ¾
x/2 < ¾ - ¼
x/2 < ½
x < 1
Draw a number line going towards left from 1, with an open circle at x=1 because x=1 is not included
