Answer: x = 4 and value is 1.4

Step-by-step explanation:

We have 0.4*(x - 0.5) = 0.2*(x + 3)

Let's first simplify this by using the distribution property.

0.4 * x = 0.4x

-0.5*0.4 = -0.2

0.2*x = 0.2x

3*0.2 = 0.6

So, now that that's over, we have: 0.4x - 0.2 = 0.2x + 0.6

Let's get rid of that 0.2 on the left to isolate x.

We do that by adding 0.2 to both sides since 0.2 is a negative number.

0.4x = 0.2x + 0.8

Now we subtract 0.2x from both sides which leaves us with: 0.2x = 0.8

Now we divide 0.8 by 0.2 to get x by itself.

x = (0.8/0.2)

x = 4

To get the value of the equation and to check our work we substitute x for 4.

0.4(x - 0.5) = 1.4

0.2(x + 3) = 1.4

In the given problem it is already given that the total number of jerseys are 50. Out of them 35 are mid sized jerseys. We can see that all required information's are already present in the problem.
Total number of medium sized jerseys = 35
Total number of jerseys = 50
Percentage of medium sized jerseys = (35/50) * 100
                                                             = 35 * 2
                                                             = 70
So 70% of the jerseys are mid sized jerseys. This is the only way to find the percentage of mid-sized jerseys. I hope this method is clear to you and you can attempt any problem like this in the future.

Answer:

62

Step-by-step explanation:

1. Divide the shape into 3 individual shapes.

2. To get the area you must multiply the width and the length.

3. Let's gather the width and the length of each shape.

Shape 1: 7 and 8

Shape 2: 2 and 3

Shape 3: 2 and 3

4. For Shape 1: 7 times 8 is 56.

5. Shape 2 and Shape 3 are equal to each other.

6. For Shape 2 + Shape 3: 2 times 3 is 6

7. Now you must add the area of all the shapes together.

Area of Shape 1: 56

Area of Shape 2: 3

Area of Shape 3: 3

8. 56 + 3 + 3 = 62

This means the area of the shape is 62.
