Answer:

63/16 or 3 15/16.

Step-by-step explanation:

Solve: 3/8[-8 + 16 - (-2 and 1/2)]  Using order of operations (PEMDAS):

=3/8[-8 + 16 - (-2.5)]

= 3/8( 8 + 2.5)

= 3/8(10.5)

= 31.5/8

Gelneren [198K]

Answer:

  1. y = -5x +10
  2. (0, 10)
  3. (1, 5)
  4. see attached

Step-by-step explanation:

1. Subtract 5x from both sides to put the equation in slope-intercept form:

  y = -5x +10

__

2. The y-intercept is the point corresponding to x=0. The y-value when x=0 is the constant in the equation: 10. Then the point is ...

  (x, y) = (0, 10)

You may notice this is one of the points listed in part 4, and is also used in question 3.

__

3. The x-value computed is 1; the y-value computed is 5. The point is ...

  (x, y) = (1, 5)

You may notice this is one of the points listed in part 4.

__

Circle O has a circumference of approximately 28.3 cm. What is the approximate length of the radius, r?
Scrat [10]

Answer:

4.5 cm.  

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

\text{Circumference of a circle}=2\pi r

Upon substituting the measure of circumference in above formula we will get,

28.3=2\pi r  

r=\frac{28.3}{2\pi}

r=4.504084889500638\approx 4.5

Therefore, the radius of circle O is 4.5 cm.

I don’t know if I’m correct but:

120➗100=1.2

Which could mean that the x could be 1.2

(I’m not sure because I haven’t done this in a long time)
(Sorry if it’s wrong)
