Answer:
x = 66
y = 68
Step-by-step explanation:
y is the same as the angle that is 68 degrees. Then, because the total of 46, x, and y should = 180, you solve for 180 by plugging in the y value.
46 + x + 68 = 180
114 + x = 180
x = 66
Answer:
The mass of the chocolate will be between 2.42 ounces and 2.58 ounces, the absolute value inequality is: ![|mass - 2.5| < 0.08](https://tex.z-dn.net/?f=%7Cmass%20-%202.5%7C%20%3C%200.08)
Step-by-step explanation:
The ideal mass of the chocolate is 2.5 ounces, although it can vary by 0.08 ounces, this variation can occur for greater masses and lesser ones. Therefore the actual mass of the each chocolate will sit between the ideal mass minus 0.08 and the ideal mass plus 0.08. Therefore we can construct the following inequality:
![-0.08 < mass + 2.58](https://tex.z-dn.net/?f=-0.08%20%3C%20mass%20%2B%202.58%20%3C0.08%5C%5C%20%7Cmass%20-%202.5%7C%3C%200.08%5C%5C)
The mass of the chocolate will be between 2.42 ounces and 2.58 ounces, the absolute value inequality is: ![|mass - 2.5| < 0.08](https://tex.z-dn.net/?f=%7Cmass%20-%202.5%7C%20%3C%200.08)
12.5 is already a decimal...
If you mean 12/5, then it is 2 and 2/5, which is 2.4.
If you mean 12 x 5, then it's 60.
If you mean fractions equivalent to 12.5 then it's 25/2.
If you mean decimals then 12.50, or 12.500.
Hope this helps
