Solve by drawing disks on a place value chart. Write an equation, and express the product in standard form. 2 copies of 4 tenths

Answers

To solve the equation by drawing disks on a place value chart, represent 2 copies of 4 tenths as disks in the tenths place. The equation is 0.4 + 0.4 = 0.8.

To represent and solve for "2 copies of 4 tenths" using a place value chart, you can follow these steps:

**Step 1:** Set up the place value chart. The place value chart includes columns for units, tenths, hundredths, and so on.

```

Units | Tenths | Hundredths | ...

```

**Step 2:** Represent the first "4 tenths." Draw four disks in the tenths place, which is the second column from the right.

```

Units | Tenths | Hundredths | ...

                 ▢ ▢ ▢ ▢

```

**Step 3:** Represent the second "4 tenths." Draw four more disks in the tenths place.

```

Units | Tenths | Hundredths | ...

                 ▢ ▢ ▢ ▢

               + ▢ ▢ ▢ ▢

```

**Step 4:** Add the two sets of "4 tenths" together. When you add them visually, you get eight disks in the tenths place.

```

Units | Tenths | Hundredths | ...

                 ▢ ▢ ▢ ▢

               + ▢ ▢ ▢ ▢

               ------------

                       ▢ ▢ ▢ ▢

```

**Step 5:** Express the sum in standard decimal form. In this case, it's 0.8.

So, 2 copies of 4 tenths is equal to 0.8 in standard decimal form.

Please answer quick!The perimeter of a rectangular herb garden is 74 feet. If the length of the garden is 5 feet longer than 3 times its width, what is the garden's width?

Answers

Answer:

Step-by-step explanation:

Using perimeter =2(l+b)

74=2(L+B)

From the question

Width(b)=x & length(l)=3x+5

So we have that

74 =2(3x+5+x)

Adding like terms we then have that

74 =2(4x+5)

Opening the bracket gives

74=8x +10

Collecting like terms

8x=74-10

8x= 64

Therefore

X=64/8

X=8feets

The width is 8feets

Answer:

8 feet.
