X=y/20-1/4 solve for y and show properties
andriy [413]

Answer:

y = 20x + 5

Step-by-step explanation:

X =  Y/20 - 1/4

In this type of expression you will first of all find the LCM of the right hand side

x = y - 5/ 20

the next thing to do is to cross multiply

we have,

20x = y - 5

dont forget we are to solve for y in the equation, so to solve for y we have

20x + 5 = y

therefore y will be expressed in terms of x as written below

y = 20x + 5

Two of the angles in a triangle measure 57º and 25°. What must be the measure of the
ira [324]

The measure of the third angle in the triangle is 104 degrees

<h3>How to determine the measure of the third angles?</h3>

Let the three angles in the triangle be x, y and z.

Such that:

x = 51

y = 25

The sum of angles in a triangle is 180 degrees.

So, we have:

x + y  + z = 180

Substitute known values

51 + 25 + z = 180

Evaluate the sum

76 + z = 180

Subtract 76 from both sides

z = 104

Hence, the measure of the third angle is 104 degrees

Don't feel bad, this is an odd question and the parenthesis do not seem to be required. Following the order of operations would result in the same answer anyway...

Odd.
