In a bag, In a bag, there are cards numbered from 1 to 10. Let: • Event A be selecting an even card • Event B be selecting a card greater than 4. What is the P(AUB)?

a² + b²= c²

24² + 7² = c²

c= 25

one that is bigger than 3 1/2

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
