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.

Answer:

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.

What is the value of n?

Valentin [98]

Answer:

n=6

Step-by-step explanation:

Consider the diagram below

Using the Theorem of Intersecting Chords

AE X ED= BE X EC

5 X n = 2 X 15

5n =30

n= 30/5 = 6

Which System of Inequalities could be used to solve the problem below?

SCORPION-xisa [38]

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.

Step-by-step explanation:

Given,

Price of one adult ticket = a = $25

Price of one youth ticket = y = $12.50

Maximum people that can be hold by theater = 1000

Therefore;

The maximum number of people can be 1000 or less than that.

$a+y\leq 1000$

As they want to revenue to be more than 15,000 therefore,

$25a+12.50y>15000$

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.

What integer is equivalent to 9 3/2

PilotLPTM [1.2K]

The answer to your question would be 10.5

Because 3/2 = 1/2 and 1/2 = 0.5 so nine plus 3/2 would equal 10.5 make sense?
