Answer:

s = 14

Step-by-step explanation:

Step 1: Combine like terms.

  • (\frac{2}{3}s + \frac{5}{6}s) = 21
  • (\frac{4}{6}s + \frac{5}{6}s) = 21
  • \frac{9}{6}s = 21
  • \frac{3}{2}s=21

Step 2: Multiply both sides by 2/3.

  • \frac{3}{2}s * \frac{2}{3} = 21 * \frac{2}{3}
  • s = \frac{42}{3}
  • s = 14

Subtract. 5x^2-5x+1-(2x^2+9x-6)
Talja [164]
<h2>Hello!</h2>

The answer is:

3x^{2} -14x+7

<h2>Why?</h2>

To solve the problem we need to add/subtract like terms. We need to remember that like terms are the terms that share the same variable and the same exponent.

For example, we have:

x^{2} +2x+3x=x^{2} +(2x+3x)=x^{2}+5x

We have that we were able to add just the terms that were sharing the same variable and exponenr (x for this case).

So, we are given the expression:

5x^2-5x+1-(2x^2+9x-6)=5x^{2}-2x^{2}-5x-9x+1-(-6)\\\\(5x^{2}-2x^{2})+(-5x-9x)+(1-(-6))=3x^{2}-14x+7

Hence, the answer is:

3x^{2} -14x+7

Have a nice day!

Nataly [62]

Answer:

- 5

Step-by-step explanation:

The opposite of 7c is the negative of 7c, that is - 7c

Thus the sum of 7c - 5 and the opposite of 7c is

7c - 5 + (- 7c) = 7c - 5 - 7c = - 5
