Which of the following is a solution to the equation x - 5/7 = -3/7

podryga [215]

Solve the equation:

      5       3
x – —— = – ——
      7       7

   5
Add —— to both sides, so you get x isolated at the left-hand side:
   7

      5       5       3 5
x – —— + —— = – —— + ——
      7        7           7       7

          3 5
x = – —— + ——
      7    7

Now, add those fractions at the right-hand side of the equation:

          – 3 + 5
x = —————
         7

        2
x = ——    <——— this is the answer (first option: 2/7).
        7

I hope this helps. =)

Pick the description of a geometric object that best matches the real-world object:<br><br> tent

Elodia [21]

Answer:

Triangular Prism

Step-by-step explanation:

We are given the object 'Tent' and are required to find a 3D object resembling it.

Since, the object represents a tent. So, it must have two similar and parallel bases with parallelograms as sides.

Therefore, we get that the 3D object that resembles a tent is a 'Triangular Prism'.

A triangular prism has two similar triangular bases and three rectangular sides as shown in the figure below.

Hence, 'Triangular Prism' is the answer.

How much greater is the area of a square with a side length of 9 inches than the area of a circle with a radius of 3 inches?

fredd [130]

The area of the square is 81 sq in, and the area of the circule is (3.14)(3 in)^2, or approx 3.14(9) sq in, or approx 28.27 sq in.

Subtract: 81 sq in - 28.27 sq in = approx. 52.73 sq in.

The difference is 52.73 sq in; the square is larger, the circle smaller.
