twice the sum of a number and 3, means you need to add the number to 3 first, then multiply by 2.

The correct expression would be 2(n+3)

7(y+3)=5y+8<br> Is this <br> A.Solution<br> B.No Solution<br> C. Infinite Solution

faust18 [17]

First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:

$a(b + c) = ab + ac$

Using this, we can multiply the 7 out to the $y$ and 3. This gives us:

$7y + 21 = 5y + 8$

Now, let's solve for $y$ :

$2y + 21 = 8$

$2y = -13$

$y = - \dfrac{13}{2}$

We can see that there is one solution for this equation because $y$ is equal to one definite value after solving. Thus, our answer is A, one solution.

Answer:

$p=\$1.50,\\c=\$0.75$

Step-by-step explanation:

We can write the following system of equations:

$\begin{cases}3p+2c=6.00,\\2p+3c=5.25\\\end{cases}$

Multiply the second equation by $-\frac{3}{2}$ to isolate and solve for $c$ :

$\begin{cases}3p+2c=6.00,\\-3p-4.5c=-7.875\\\end{cases},\\-2.5c=-1.875,\\c=\fbox{$\$0.75$}$ ,

Now plug in $c=0.75$ into any equation to solve for $p$ :

$3p+2(0.75)=6.00,\\3p=4.50,\\p=\fbox{$\$1.50$}$ .

Write the equation in standard form for the circle with center (0, -6) and radius 7.

LUCKY_DIMON [66]

Step-by-step explanation:

the equation of circle is given by

$(x - h) {}^{2} + (y - k) {}^{2} = {r}^{2} \\ (x - 0) {}^{2} + {(y + 6)}^{2} = {7}^{2} \\ {x }^{2} + {y}^{2} + 12y + 36 = 49 \\ {x }^{2} + {y}^{2} + 12y = 13$
