Answer:

x = -14

Step-by-step explanation:

The expression to write in this problem is:

"the sum of x and 12 equals the sum of half of x and 5"

We have:

- The sum of x and 12 is: x+12

- The sum of half of x and 5 is: \frac{1}{2}x+5

So, the equation to write in this problem is

x+12=\frac{1}{2}x+5

We solve it as follows:

1) First, we subtract \frac{1}{2}x from both sides, and we get

x-\frac{1}{2}x+12=\frac{1}{2}x-\frac{1}{2}x+5\\\frac{1}{2}x+12=5

2) Then, we subtract 12 from both sides:

\frac{1}{2}x+12-12=5-12\\\frac{1}{2}x=-7

3) Now we multiply both sides by 2:

\frac{1}{2}x\cdot 2=-7\cdot 2\\x=-14

So, this is the solution.

Lets say travi's rope is T feet long
and Stacy's rope is 23 feet long
3T-4=23
3T=23+4
3T=27
T=9 feet long
so Travis rope is 9 feet long

5. Write two expressions for the area of the big rectangle. ​
4vir4ik [10]

Answer:

Two expressions for the area are;

i) x/3 + 2·y + 6

ii) (1/3) × (x + 6·y + 18)

Step-by-step explanation:

The given dimension of the rectangle are;

The height of the rectangle, h = 1/3

The width of the smallest rectangle, w₁ = x

The width of the med sized rectangle, w₂ = 6·y

The width the large rectangle, w₃ = 18

The area, 'A', of the entire rectangular figure, the big rectangle, can be expressed as follows;

A = A₁ + A₂ + A₃

Where;

A₁ = The area of the smallest rectangle

A₂ = The area of the mid sized rectangle

A₃ = The area of the large rectangle

∴ A = (1/3) × x + (1/3) × 6·y + (1/3) × 18 = x/3 + 2·y + 6

The area of the big rectangle. 'A', can also be found as follows;

A = (1/3) × (x + 6·y + 18)

Therefore, two expressions for the area of the big rectangle are;

x/3 + 2·y + 6 and (1/3) × (x + 6·y + 18).

If you graph the points it comes out as a square, so the correct answers would be square, rectangle, parallelogram, and rhombus (a square can be these three but these shapes cannot be squares)
