Answer:
30
Step-by-step explanation:
538 = 540
509 = 510
40 - 10 = 30
Answer:
The correct answer is B. 30.
Step-by-step explanation:
538 - 509 = 29
Since we need to round this to the nearest tens place, that means we need to round it to 10, 20, 30, etc.
When rounding a number, you look at the last number in it. If it is a 5 or higher, you round up the number before it by 1. If it is a 4 or lower, the number before it stays the same and the lowest number turns into a 0.
Since 9 is higher than 5, the 2 in 29 will turn to a 3, and the 9 will turn into a 0.
Therefore, the correct answer is B. 30.
Hope this helps! :D

What are equivalent expressions?
Answers
Answer:
Consider the expressions 32+1 and 5×2 . Both are equal to 10 . That is, they are equivalent expressions.
Now let us consider some expressions that include variables, say 5x+2 .
The expression can be rewritten as 5x+2=x+x+x+x+x+1+1 .
We can re-group the right side of the equation to 2x+3x+1+1 or x+4x+2 or some other combination. All these expressions have the same value, whenever the same value is substituted for x . That is, they are equivalent expressions.
Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them.
Example 1:
Are the two expressions 2y+5y−5+8 and 7y+3 equivalent? Explain your answer.
Combine the like terms of the first expression.
Here, the terms 2y and 5y are like terms. So, add their coefficients. 2y+5y=7y .
Also, −5 and 8 can be combined to get 3 .
Thus, 2y+5y−5+8=7y+3 .
Therefore, the two expressions are equivalent.
Example 2:
Are the two expressions 6(2a+b) and 12a+6b equivalent? Explain your answer.
Use the Distributive Law to expand the first expression.
6(2a+b)=6×2a+6×b =12a+6b
Therefore, the two expressions are equivalent.
Answer:
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).

Mary used the equation x = $4 * y to represent the table above. What mistake did she make, and what should the correct equation be to represent this table?
Answers
Answer: she has to remove the $ sign from the equation
Step-by-step explanation:
We know this because $4.00x$5.00=$20.00 so that’s correct and we know that $12.50x $4.00=$50.00. So, our only error here is that there is no dollar sign in our (X) numbers. So that is Mary’s mistake. We can correct it by simply adding a dollar sign to 20 to make $20.00 and adding another dollar sign to 50 to make $50.00

The distance between City A and City B is 250 miles. A length of 1.9 feet represents this distance on a certain wall map. City C and City D are 4.94 feet apart on this map. What is the actual distance between City C and City D?
Answers
131.6 x 4.94 = 650.1
The actual distance is 650.1 miles
Hope this helps x
Answer:
"What is the actual distance between City C and D?"
650 miles
Step-by-step explanation:
From what I can understand (d) will represent our missing distance...
first, we'll cross multiply like so [tex]\frac{250mi}{1.9ft} = \frac{d}{4.94ft}[/tex] then you would end up with 250(4.94) = 1.9(d) next reposition them like this [tex]\frac{250(4.94)}{1.9} = d[/tex] and solve from here 250(4.94) = 1,235 divides this by 1.9 [tex]\frac{1,235}{1.9} = d[/tex] finally, you have your answer 650 = d

What is the sign of the product (8)(−23)(−21)(−29)?
Options:
A) Positive, because the products (8)(−23) and (−21)(−29) are negative, and the product of two negative numbers is positive
B) Positive, because the products (8)(−23) and (−21)(−29) are positive, and the product of two positive numbers is positive
C) Negative, because the product (8)(−23) is positive and the product (−21)(−29) is negative, and the product of a positive number and a negative number is negative
D) Negative, because the product (8)(−23) is negative and the product (−21)( −29) is positive, and the product of a negative number and a positive number is a negative number

Answer:
D) Negative, because the product (8)(−23) is negative and the product (−21)( −29) is positive, and the product of a negative number and a positive number is a negative number
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
If there are an even number of negative signs, the product will be even.
If there is an odd number of negative signs, the product will be odd.
In this case, there are 3 negative signs, so the product will be negative.
It's D.
*Note: it's not C because the product of (8) and (-23) is negative, not positive because there is only one negative sign, not two.
