If the product of a number and -8 is subtracted from the number, the result is 7 more than the number. find the number. Use x for the number.x-(-8x)=

Answers

Answer 1
Answer: x-(-8\cdot x)=x+7\n\nx-(-8x)=x+7\n\nx+8x=x+7\n\n9x=x+7\n\n9x-x=x+7-x\n\n8x=7\n\n8x:8=7:8\n\nx=(7)/(8)
Answer 2
Answer: You have said that  [  x - (-8x) = x + 7  ] .

Note that  [ - (-8x) ] = 8x

So the equation may be written as  [  x + 8x = x + 7  ] .

Add up the 'x's on the left side:            9x = x + 7

Subtract 'x' from each side:                  8x = 7

Divide each side by 8 :                        x = 7/8

Evaluate the expresson when n=8 The product of one fourth and a number increased by 3

Answers

Answer:

5

Step-by-step explanation:

Substitute the n for 8 in

((1)/(4) times n)+3

product means multiply, so

((1)/(4) times 8)+3

First multiply (1)/(4) by 8 to get 2

(1)/(4) · 8 = 2

Then add 2 and 3

2+3=5

Final answer:

To simplify √18, we first find the prime factors of 18, then use those factors to rewrite √18 in a simplified form. For 18, which is 2 * 3^2, the square root simplifies to 3√2.

Explanation:

The goal here is to simplify √18. To begin, we find the prime factors of 18. The prime factors of 18 are 2 and 3. Hence 18 can be written as 2 * 3 * 3 or 2 * 32. We substitute this representation into our original expression, √18 becomes √(2 * 32). From our knowledge of square roots, we know that √(a2) can be simplified to 'a'. That is, the square root of the square of a number is the number itself.  Hence, √(32) can be simplified to 3. So we have √(2 * 32) = √2 * 3 = 3√2. So, the simplification of √18 is 3√2.
