Sandra says that 4\7-1\3=3\4because all you have to do is subtract the numerators and subtract the denominators. convince sandra that she is wrong

The answer is

Step-by-step explanation:

Given that Sandra says that

Sandra do the above calculation by subtracting the numerators and subtracting the denominators. we have to convince that Sandra is wrong.

The method of above calculation is wrong. the correction calculation is done by taking the LCM of denominators so that denomination will become same and then we will subtract the denominator.

This is the correct method.

therefore, sandra is wrong.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
