Answer:

Step-by-step explanation: The area of a circle can be found with the equation A=(pi)*r^2. Use the equation to find the answer:

A=(pi)*5.5^2 (or A=3.14*5.5^2)

A=94.99 or 95.03 in exact pi

Sandy has several pictures of to hold lemonade for the school bake sale two pictures can hold 64 ounces each and four pictures c

disa [49]

We know that there are 2 pitcher of 64 ounces and 4 pitcher of 48 ounces.
To find the numerical expression, we must do:
(64×2)+(48×4)=Total amount of lemonade
128+192=320 ounces
So, Sandy has 320 ounces of lemonade.

Doss [256]

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given inequality

$-18x+3$

STEP 2: Solve for x

$\begin{gathered} -18x+3\frac{-45}{18} \\ x>-\frac{5}{2} \\ x>-2.5 \end{gathered}$

STEP 3: Plot the number line for that represents the final solution

Hence, the number line that best represents the final solution can be seen in the number line below:

3x + 6y= 180<br>What is x and y

Diano4ka-milaya [45]

Answer and explanation:

3x + 6y = 180 <em>Use the original expression to find x</em>

3x = 180 - 6y <em>Subtract 6y by both sides</em>

$\frac{3x}{3} = \frac{180}{3} - \frac{6y}{3}$ <em>Divide by 3 to get x</em>

x = 60 - 3y

x = 60 - 3y <em>Use the new expression to find y</em>

x - 60 = - 3y <em>Subtract 60 by both sides</em>

$\frac{x - 60}{-3} = \frac{-3y}{-3}$ <em>Divide by -3 to get y</em>

$-\frac{x}{3} + 20 = y$
