Answer:

-6c + 7

Step-by-step explanation:

To simplify this expression, you must add like terms. Because 3c and -9c both have the same variable (c), they are like terms.

3c + (-9c) = -6c

The 7 stays the same, so the simplified expression is -6c + 7.

Hope this helped :)

Answer:

The value of the expression for x=3 is 51

Step-by-step explanation:

Evaluating expressions

To evaluate a given expression, we simply substitute the value of the variables and complete the operations.

The expression to evaluate is:

P=3(2+5x)

We will evaluate for x=3:

P=3(2+5*3)

The product must be done first:

P=3(2+15)=3*17=51

The value of the expression for x=3 is 51

0.5s +1=7 + 4.5s S =

kvv77 [185]

Answer:

$s = -\frac{3}{2}$

Step-by-step explanation:

Solve for the value of $s$ :

$0.5s + 1 = 7 + 4.5s$

-Combine both $0.5s$ and $4.5s$ by subtracting $0.5s$ by $4.5s$ :

$0.5s + 1 - 4.5s = 7 + 4.5s - 4.5s$

$-4s + 1 = 7$

-Subtract $1$ to both sides:

$-4s + 1 - 1 = 7 - 1$

$-4s = 6$

-Divide both sides by $-4$ :

$\frac{-4s}{-4} = \frac{6}{-4}$

$s = -\frac{3}{2}$

So, the value of $s$ is $-\frac{3}{2}$ .
