a = 56

given 28 = \frac{1}{2} a

multiply both sides by 2 to eliminate the fraction

56 = a

As a check

\frac{1}{2} × 56 = 28 ← True

What is 37+8x=4(7-x)
nadezda [96]
Simplifying
37 + 8x = 4(7 + -1x)
37 + 8x = (7 * 4 + -1x * 4)
37 + 8x = (28 + -4x)

Solving
37 + 8x = 28 + -4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4x' to each side of the equation.
37 + 8x + 4x = 28 + -4x + 4x

Combine like terms: 8x + 4x = 12x
37 + 12x = 28 + -4x + 4x

Combine like terms: -4x + 4x = 0
37 + 12x = 28 + 0
37 + 12x = 28

Add '-37' to each side of the equation.
37 + -37 + 12x = 28 + -37

Combine like terms: 37 + -37 = 0
0 + 12x = 28 + -37
12x = 28 + -37

Combine like terms: 28 + -37 = -9
12x = -9

Divide each side by '12'.
x = -0.75

Simplifying
x = -0.75

A pyramid has a square bade with side s. The height of the pyramid is 2/3 that of its side. What is the expression for the volum
Citrus2011 [14]

Answer:

V = (2/9)s³

Step-by-step explanation:

The general formula for the volume of a pyramid is:

V = (1/3)(base area)(height).

Here,  the length of a side of the square base is s, and so the area is A = s².  For the height we use (2/3)s.  Then  the volume of the pyramid is:

V = (1/3)(s²)(2/3)s, or V = (2/9)s³

Do the opposite angles in a parallelogram have the same measure please explain why
asambeis [7]
Yes, opposite angles in a parallelogram always have equal measures. This is a defined property of parallelograms and an easy way to check if the shape is one. Since a parallelogram has 4 angles and the 2 sets of sides are parallel, any 2 adjacent angles have a sum of 180 degrees. Using this, the 2 adjacent angles to any one angle must be opposite to each other and therefore equal.
