Answer:549-238=311
311-130=181
Step-by-step explanation:
Answer:
3x = 50 - 10y
Step-by-step explanation:
Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,
So, total weight of 3 lb weights = 3x
And, the weight of 10 lb weights = 10y
Total weight of all his weights = 3x + 10y
According to the question,
Total weight = 50 lb,
⇒ 3x + 10y = 50
Or 3x = 50 - 10y
Which is the required equation.
Second option is correct.
The algebraic expressions would be 300/(b + 24). The important thing to note here is that you have a dividend and a divisor in a division problem. The first piece of info (300) is the dividend, the numerator if you are writing it in fraction form or the first number when using the standard division sign. The divisor is the SUM OF b + 24 which means you need to find the answer before dividing by it. To show that you will add first, place a parentheses around it. This is an expression, so there should be NO equals sign. It is not a complete sentence.
