You may feel somewhat overwhelmed right now, because this question is giving the reader lots of information and tasks in a short paragraph. Let's break it down into pieces.

1. First, let's find the ratio of the lengths.

Since the ratio is 7 to 3, we can find the length of each licorice piece by setting its proportion over 10, since that is the sum of the ratio. Thus, one licorice piece has a length of 60 * 7/10 = 42 cm and the other has a length of 60 * 3/10 = 18 cm.

2. Now, let's create our squares.

Each piece is bent to form a square. In other words, the pieces is split into 4 equal sides. Thus, we can divide our lengths by 4. The first piece of licorice made into a square has side lengths of 42/4 = 10.5 cm. The second piece of licorice has side lengths of 18/4 = 4.5 cm.

3. Finding the area of our squares.

Now, all we need to do is find the sum of the areas of the squares. The first square has an area of 10.5^2 = 110.25 cm^2 and the second square has an area of 4.5^2 = 20.25 cm^2. Thus, our answer is 130.5 cm^2.

Answer:

A) y = 4x - 1

Step-by-step explanation:

y = mx + b

y = 4x + b

7 = 4(2) + b

7 = 8 + b

-1 = b

y = 4x - 1

Find the slope between the points. (4,-2) and (8,5)
aksik [14]
Slope = m

Equation to find slope is:

m = (y2 - y1) / (x2 - x1)

2 points:
(4,-2) 4 = x1 and -2 = y1
(8,5) 8 = x2 and 5 = y2

So...

m = (y2 - y1) / (x2 - x1)

m = (5 - (-2)) / (8 - 4)

m = 7 / 4 or 1.75

Therefore, the slope of the line is 7/4 OR 1.75.

C. Solve 1/2 x - (x+3)<1/3(x-1)​
MAVERICK [17]

Answer: x = 28

Step-by-step explanation:

Let's solve your equation step by step!

3/8x + 15/2 = 18

Step 1: Subtract 15/2 from both sides.

3/8x + 15/2 - 15/2 = 18 - 15/2

3/8x = 21/2

Step 2: Multiply both sides by 8/3

(8/3) * (3/8x) = (8/3) * (21/2)

Step 3. Calculate

x = 28
