The value of x and the value of y
egoroff_w [7]

Answer:

x= 60 y=50

Step-by-step explanation:

First to find x, all the degrees in a triangle add up to 180 degrees. So 50+70+x=180 which is also 120+x=180 which means x=60. Y is the exterior angle of x and a missing angle. Let's substitute the missing angle with the variable z. 60+50+z=180 which is 110+z=180 which means z is 70. So 180-x+z=y. 180-60+70=y which means y is equal to 50. Hope this helps!

Answer:

<u>4.63 as simplified fraction is</u>

<u>463/100</u>

Step-by-step explanation:

<em>4.63 as a fraction in simplest form</em>

<em>To convert 4.63 to fraction, follow these steps:</em>

<em />

<em>First write down the decimal number divided by 1 like this:</em>

<em />

<em>4.63/1</em>

<em />

<em>As we have 2 digits after the decimal point in the numerator, we need to multiply both the numerator and denominator by 10² = 100, so that there is no decimal point in the numerator</em>

<em />

<u><em>4.63 × 100</em></u>

<em>    1 × 100</em>

<em> = </em>

<em>463/100</em>

<em />

<em>As the numerator is greater than the denominator, we have an improper fraction, so we can also express 4.63 as a mixed number, thus 463/100 is equal:</em>

<em />

<em>4 63/100</em>
