Answer:
3x=50-10y
Step-by-step explanation:
Just took the test on ed.
The given problem is a system of equations problem. The equation that represents how many of each type of weight Bob has is 3x + 10y = 50, where x represents the number of 3 lb weights and y represents the number of 10 lb weights.
In this scenario, we're given that Bob has a combination of 10 lb and 3 lb weights. If we let x represent the number of 3 lb weights and y represent the number of 10 lb weights, we know that all of his weights together total 50 lbs. This information leads us to a system of equations problem.
Since the weights of the 3 lb and 10 lb weights multiplied by their respective quantities (x and y) gives us the total weight, we can summarize this in an equation. The equation 3x + 10y = 50 would represent this scenario and could be used to find the number of each type of weight Bob has.
This equation is based on the principle of weight summation: the weight of each type of weight (3 lbs and 10 lbs) times the number of each type of weight when added together should equal the total weight (50 lbs).

The probability of drawing a 6 is
(Type a whole number or a simplified action.)
Actually Welcome to the Concept of the Probabilities.
Here, In the game of cards, we have total number of 52 cards in a deck. Since here we have to find the probability of Card 6 from the whole deck.
Let's solve,
Total Number of Cards we have = 52
Total number of 6 numbered Cards in deck = 4
Hence, probability = Favourable Outcomes ÷ Total No. of Outcomes.
So, the Probability of getting a 6 Card = 4/52
= 1/13
Hence the probability is 1/13.
a. –11.81
b. –5.71
c. 5.71
d. 11.81
