2p + 5 = 3 - p\\2p + p + 5 = 3 - p + p\\3p + 5 = 3\\3p + 5 -5 =3 - 5\\3p = -2\\\frac{3p}{3} = -\frac{2}{3} \\\\p = -\frac{2}{3}

3-2x = 8x-7\\3 - 2x + 2x = 8x + 2x -7\\3 = 10x - 7\\3 + 7 =10x - 7 + 7\\10 = 10x\\\frac{10}{10} = \frac{10x}{10} \\\\x = 1

Determine which set of side measurements could be used to form a right triangle.
musickatia [10]

The set of side measurements that could be used to form a right triangle is 3, 4 and 5 option (D) is correct.

What is a right-angle triangle?

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

It is given that:

The side length of the triangle is shown in the option:

As we know,

Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

Using Pythagoras' theorem:

From option(D):

3, 4 and 5

(3)² + (4)² = 5²

9 + 16 = 25 (True)

Thus, the set of side measurements that could be used to form a right triangle is 3, 4 and 5 option (D) is correct.

Convert 0.827 to a fraction or in simplest form
dangina [55]
<span>0.827 = 0.827 / 1


Numerator = 0.827 × 10 × 10 × 10 = 827
Denominator  = 1 × 10 × 10 × 10 = 1000

Numerator / Denominator = 827 / 1000

Simplifying our fraction

= 827/1000

= 827/1000</span>
