Answer 1

Answer:

Answer:

I believe it is 27

Step-by-step explanation:

Answer 2

Answer:

Answer: x = 27

Step-by-step explanation:

To solve this, first insert 4 for y:

3x - 4 * 4 = 65

Next, multiply the numbers:

3x - 4 * 4 = 65

3x - 16 = 65

Next, move the constant to the right and change its sign:

3x - 16 = 65

3x = 65 + 15

Next, add the numbers:

3x = 65 + 16

3x = 81

Finally, divide both sides of the equation by 3:

3x = 81

3x ÷ 3 = 81 ÷ 3

(Any expression divided by itself equals 1)

3x ÷ 3 = 81 ÷ 3

x = 81 ÷ 3

x = 81 ÷ 3

x = 27

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Chuanxi planned a rectangular sidewalk with a length of 21 ft. He made a scale drawing using a scale factor of 1 in. = 7 ft. He decided to change the length of the actual sidewalk to 27 ft.

The value of 1 inch will be calculated as,

Original Ratio of 1 in = 7 ft so 3 in = 21 ft

Now, New ratio 1 in = x ft so 3 in = 27ft
