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.

Answers

Answer:

27

Step-by-step explanation:

the sum of both of these angles would be 180

45+5x=180

5x=180-45

5x=135

x=27

So first you cut the shape into two triangles. One triangle is 180 so you would do 45+45+5x+5x=360. SP then you add up the numbers 45+45=90 then you would do the same for 5x+5x =10x. Now that you have both numbers you’re able to subtract 90 from 360 and that equals 270 now you do 270 divided by 10x and that equals 27

from 22 kilograms of fresh mushrooms, 2.5 kilograms of dry mushrooms are obtained, containing 12% water. What is the percentage of water in fresh mushrooms?

(I didn’t really understand the problem’s wording, so you don’t have to give me an answer if you aren’t able to. Just an approach at it.)

Answers

Answer:114

Step-by-step explanation:

i am smart

The percentage of water in fresh mushrooms is 10 percent.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, from 22 kilograms of fresh mushrooms, 2.5 kilograms of dry mushrooms are obtained, containing 12% water.

Let x% of water in fresh mushrooms.

Here, x% of 22 = (100-12)% of 2.5

x/100 ×22 = 88% of 2.5

22x/100= 88/100 ×2.5

22x=88×2.5

x=4×2.5

x=10%

Therefore, the percentage of water in fresh mushrooms is 10 percent.

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
