What is the greatest common factor of 16 and 40?
myrzilka [38]

Answer:

<h3> 8 </h3>

Step-by-step explanation:

16 divided by 8 is 2. 40 divided by 8 is 5. Neither of these can be reduced by any more common numbers, so therefore, 8 is your greatest common factor. The GCF of 16 and 40 is 8.

Part A picture above
-BARSIC- [3]

Answer:

<em>Part A </em>C = (10,5)<em>  Part B </em>C. D'(0,10)

Step-by-step explanation:

<em>Part A</em>

Since c is at the point (2,1) in relation to the origin, we can multiply those distances by our scale factor of 5

(2,1) * 5 = (10,5)

The new point C is going to be (10,5)

<em>Part B</em>

If you dilate with a factor of 5 -- relative to the origin -- you have to multiply the distance from <em>the origin</em> by 5.

In this case, point D is already on the y axis, so it's x value wouldn't be affected. Point D is currently 2 units away from (0,0), so we can multiply 2*5 to get 10 -- our ending point is (0,10)

Can somebody please help me figure this out?
Vera_Pavlovna [14]

Answer: You would put the 35° and the 4x+7° equal to each other.

Step-by-step explanation:

    1. 4x+7=35  

    2. 4x+7=35   -> Subtract 7 from the positive 7 and the 35

           -7     -7

    3. 4x=28       -> Divide 4x and 28

    4. x=7
