Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or ...

Given the rectangle below, write a simplified expression that represents the perimeter and terms of x. Use your expression to so

Tatiana [17]

The expression representing the perimeter is 6x + 39

x = 3. 8

<h3>What is the perimeter?</h3>

The formula for perimeter of a rectangle is given as;

Perimeter = 2 ( length + width)

From the image shown, we have that:

length = 2x
width = x + 13

Now, let's substitute the value

Perimeter = 2 ( 2x + x + 13)

collect like terms

Perimeter = 2 ( 3x + 13)

Expand the bracket

Perimeter = 6x + 39

If perimeter = 62

62 = 6x + 39

6x = 62 - 39

6x = 23

x = 23/ 6

x = 3. 8

Thus, the expression representing the perimeter is 6x + 39

Answer:

40 children went on the cruise.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of adults on the cruise

y is the number of children on the cruise.

57 tickets were sold:

This means that $x + y = 57$ , and since we want the number of children y, $x = 57 - y$

Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.

This means that:

$22x + 10y = 774$

Since $x = 57 - y$

$22(57 - y) + 10y = 774$

$1254 - 22y + 10y = 774$

$12y = 480$

$y = \frac{480}{12}$

$y = 40$

40 children went on the cruise.
