Answer:

Step-by-step explanation:

In order to find the answer. You first have to find the measure of the whole circle, which is 180.

Then you subtract 180-95 to find y.

180-95=85

So y=85

Then you subtract 180 from 80

180-80=100

So x=100

z=80

So the answer is D.

vaieri [72.5K]

Answer:

Hiroshi's error was not having changed the sign of the number 37 by removing the parentheses and placing -37 instead of +37.

Step-by-step explanation:

we have

Hiroshi's work

$42-(-37)=42-37=5$

Remember that

a negative number is just a positive number multiplied by -1

and (-1)(-1)=+1

Correct work

$42-(-37)$

$42-(-1)(37)$

$42-(1)(-1)(37)$

$42+(-1)(-1)(37)$

$=42+37=79$

therefore

Hiroshi's error was not having changed the sign of the number 37 by removing the parentheses and placing -37 instead of +37.
