What is the missing numerator?

Mathematics
1 answer:
N76 [4]2 years ago
3 0

Answer:

  3

Step-by-step explanation:

As with any other addition fact problem, you can isolate the unknown term by subtracting the unwanted constant.

  5/7 +x/6 = 51/42

  x/6 = 51/42 -5/7 . . . . . subtract 5/7 from both sides

  x/6 = 51/42 -30/42 = 21/42 = 1/2 . . . . . complete the subtraction

  x = 6(1/2) = 3 . . . . . . . . multiply by 6

The missing numerator is 3.

_____

<em>Alternate solution</em>

Multiply the equation by 42:

  30 +7x = 51

  7x = 51 -30 = 21 . . . . . subtract 30

  x = 21/7 = 3 . . . . . . . . divide by the coefficient of x

A hockey player knows that the two goal posts of a hockey net are 1.83 meters apart. The player tries to score a goal by shootin
Luden [163]

The distance the player is from the right post is = 5.1 meters

<h3>Calculation of distance using Pythagorean theorem</h3>

The Pythagorean theorem states that the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.

Formula for the Pythagorean theorem =

a²= b²+c²

From the diagram given,

The hypotenuse (a) = x²

b= 1.82²

c = 4.8²

x² = 1.82² + 4.8²

x²= 3.3124 + 23.04

x²= 26.3524

a= √26.3524

a= 5.1 meters.
