Answer:
x = 11/2
Step-by-step explanation:
We would first put it in an equation
5x - 1 = 10 + 3x
We would first add 1 on both sides
5x = 11 + 3x
Then we subtract 3x on both sides
2x = 11
Divide both sides by 2
x = 11/2

1st urn....4 green balls, 6 blue balls.....10 total balls....probability of drawing a blue ball in urn 1 is : 6/10 reduces to 3/5
2nd urn...6 green balls, 2 blue balls....8 total balls...probability of drawing a blue ball in urn 2 is : 2/8 reduces to 1/4
probability both balls are blue : 3/5 * 1/4 = 3/20 <==
Answer:
Television = $200 and DVD player = $450
Step-by-step explanation:
→ Make 2 equations
Televisions = t and DVD players = d
2t + 3d = 1750
4t + d = 1250
→ Multiply the bottom equation by 3 to make the same variable of d
2t + 3d = 1750
12t + 3d = 3750
→ Minus the two equations to isolate the d variable
-10t = -2000
→ Divide both sides by -10 to find the cost of one television
t = 200
→ Substitute t = 200 back into 4t + d = 1250
800 + d = 1250
→ Minus 800 from both sides to isolate d
d = 450
