It is given that the measurement of arc AC = 155 . And AB is the diameter, so measurement of arc AB=180 degree . Therefore arc BC = arc AB - arc AC = 180-155=25 . And the radius divides chord CD in two equal parts, so it divides the arc too in two equal parts. Therefore if the measurement of arc CB =25 , then the measurement of arc BD =25 too. Hence x =25 .

What is the solution to the equation |x − 4| = 17?

andrey2020 [161]

$~~~~~~|x-4| = 17\\\\\implies x -4 = 17~~~~ \text{or}~~~~~ x -4 = -17\\\\\implies x = 17+4~~~~\text{or}~~~~~ x = -17+4\\\\\implies x = 21~~~~~~~~~\text{or}~~~~~x = -13$

8x - 2 = -9 + 7x what does x equal

Nimfa-mama [501]

Answer:

x = - 7

Step-by-step explanation:

8x - 2 = -9 + 7x (add 2 to both sides)

8x - 2 + 2 = -9 + 7x + 2

8x = 7x - 7 (subtract 7x from both sides)

8x - 7x = 7x - 7 - 7x

x = - 7

A ream of paper contains 500 sheets of paper. Norm has 373 sheets of paper left from a ream. Express the portion of a ream Norm

Lunna [17]

Answer: In fraction : $\dfrac{373}{500}$

In Decimal : 0.746

Step-by-step explanation:

Given : A ream of paper contains 500 sheets of paper.

Norm has 373 sheets of paper left from a ream.

Then, the fraction of ream Norm has will be :-

$\dfrac{\text{Number of sheets left from ream }}{\text{Total sheets in a ream }}\\\\=\dfrac{373}{500}$

To convert in decimal we divide 373 by 500, we get 0.746.

Hence, The portion of a ream Norm has as = $\dfrac{373}{500}$ or 0.746
