Write the other side of this equation so it's true for no values of x:

1/3(12x + 18) + x

Answers

To make the equation true for no values of x, we need to make sure that the left-hand side and the right-hand side are not equal for any value of x.

Let's simplify the left-hand side of the equation first:

1/3(12x + 18) + x
= 4x + 6 + x
= 5x + 6

To make this equation true for no values of x, we need to find an expression that is never equal to 5x + 6. One way to do this is to take the negative of 5x + 6:

-(5x + 6)

Now the full equation is:

1/3(12x + 18) + x = -(5x + 6)

We can simplify the left-hand side again:

1/3(12x + 18) + x
= 4x + 6 + x
= 5x + 6

And substitute it into the equation:

5x + 6 = -(5x + 6)

Simplifying this equation gives:

10x + 12 = 0

Dividing both sides by 10 gives:

x + 6/5 = 0

x = -6/5

So the original equation, 1/3(12x + 18) + x = -(5x + 6), is true for no values of x.

Does the sentence Carita uses 5 1/2 times as much wood as Thomas" Mean you going to multiply or subtract?

Answers

Multiply!

Carita has MORE wood than Thomas. For example, if Thomas has 1 piece of wood, Carita has 5.5 pieces of wood. If he had 2 pieces, Carita has 2x5 1/2 = 11 pieces of wood.

“*Times* as much…” implies multiplication. The x sign is a ‘times sign’, and “times” is synonymous with “multiplication”.

Sofia needs 8 inches of ribbon to make 1 party favor. Which of the following lengths would be enough ribbon for Sofia to make from 15 to 20 party favors? 1 inch 5 2.54 centimeters, 1 centimeter < 0.39 inch
A 61 centimeters
B 390 centimeters
C 405 centimeters
D 411 centimeters
E 490 centimeters

Answers

First, we need to determine how much ribbon Sofia needs for each party favor. Since she needs 8 inches of ribbon for one party favor, we can convert that to centimeters (since the answer choices are given in centimeters):

8 inches x 2.54 cm/inch = 20.32 cm

So Sofia needs 20.32 cm of ribbon for each party favor.

To find out how much ribbon she needs for 15 to 20 party favors, we can multiply the amount needed for one party favor (20.32 cm) by the number of party favors:

15 party favors x 20.32 cm/party favor = 304.8 cm
20 party favors x 20.32 cm/party favor = 406.4 cm

The closest answer choice to this range is C, 405 centimeters. Therefore, C is the correct answer.

Answer:

D: 411 centimeters

Step-by-step explanation:

Multiply 8 by 15 you'll get 120 inches from thisMultiply that by 2.54 to find how many centimeters it is. It would be 304.8 centimeters.Then repeat steps 1-2 but replace 15 inches with 20 inches. When you multiply it by 8 it becomes 160 and it becomes 406.4 centimeters when it's multiplied by 2.54 which is why the correct answer is D
