Answer:
1/10
Step-by-step explanation:
1/5 to land on the spinner, and 1/2 to land on tails. Compound prob = we gotta multiply the probabilities so we get 1/10
3x +4y = 8
y = 3/4x - 2
Substitution Method
3x + 4(3/4x -2) = 8
Distributive Property:
3x + 3x -8 = 8
Simplify:
6x -8 = 8
Add 8 to each side:
6x = 16
Divide both sides by 6"
x = 16/6
x = 2 2/3
Now replace x with that and solve for y:
y = 3/4(2 2/3) - 2
y = 2-2 = 0
y=0
7.5x - 100 > 79.86 + 5.8x
7.5x - 5.8x > 79.86 + 100
1.7x > 179.86
x > 179.86 / 1.7
x > 105.8
