Answer from: micahmereus100

Correct option is C

Step-by-step explanation:

Given the two expression

and

Anja is substituting t=5 and t=9 to determine if the two expressions are equivalent. we have to choose the correct statement.

First exp: 4(2t-5)

Substitute

t=5: 4(2(5)-5)=4(10-5)=20

t=9: 4(2(9)-5)=4(18-5)=4(13)=52

Second exp: 10t-38

t=5: 10(5)-38=50-38=12

t=9: 10(9)-38=52

Both expressions are equivalent when t=9, but the two expressions are not equivalent.

Hence, correct option is C

Answer from: bryantjorell

option (b) is correct.

Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.

Step-by-step explanation:

Given : A math class is having a discussion on how to determine if the expressions 4x - x + 5 and 8 - 3x - 3 are equivalent using substitution.

We have to choose the correct method from the given options that the class has suggested.

Since we have to show the given expressions 4x - x + 5 and 8 - 3x - 3 are equivalent using substitution.

We will choose a single value of x and then evaluate both the given expression at that single value and if the output of both expression comes out to be same then the two expressions must be equivalent.

For example lets take x = 2,

Then expression 4x - x + 5 becomes 4(2) - 2 +5 = 8 - 2 + 5 = 6 + 5 = 11

also, expression 8 - 3x - 3 becomes 8 - 3(2) - 3 = 8- 6 - 3 = 8 - 9 = -1

thus, the value is not equal hence, the two expression are not equivalent.

Thus, option (b) is correct.

Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent.

Answer from: lestessanders02

not equivalent5+5+5 ≠ 4(5)

Step-by-step explanation:

The expressions are not equivalent.

5+5+5+ X plus X plus X plus X is equivalent to 3·5 +4·X. There is no common factor of 4 that can be removed using the distributive property.

Comment on the problem

We can only go by what is posted here. If your problem is actually different, then the answer may be different.

Answer from: Spoiledgirl2905

The answer is C because when t=9, the equations are equal, but the expressions themselves are not equal to each other.
