<h3>Answer: Choice C) 2</h3>

=======================================================

Explanation:

The vertical side of the blue triangle is PR = 2

The corresponding vertical side of the green triangle is P'R' = 4

The scale factor is the ratio of those two corresponding sides. So we divide the two side lengths.

scale factor = (P'R')/(PR) = (4)/(2) = 2

---------------------

We could also say:

scale factor = (R'Q')/(RQ) = (6)/(3) = 2

Or you could find the lengths of PQ and P'Q' through the distance formula, or Pythagorean theorem, and apply the same idea as shown above.

Giovanna has a score of -5 in canasta Vera score is -10
MariettaO [177]

Answer:

5

Step-by-step explanation:

I do not fully understand what the question is because you didn't ask a question, so I just found the difference between the 2 scores, which would be a positive 5.

Or if its asking which score is greater it would be Giovanna because her score was closer to zero than Vera's score.

14.12 = 1/2 (3.6x - 12.8)<br><br> show work
Sergio039 [100]

Answer:

x = 11.4

Step-by-step explanation:

14.12 = \frac{1}{2} ( 3.6x - 12.8 )

Rewrite so that the equation is entirely in decimals;

14.12 = 0.5( 3.6x - 12.8 )

Distribute;

14.12 = 1.8x - 6.4

Inverse operations;

14.12 = 1.8x - 6.4

+6.4            +6.4

20.52 = 1.8x

/1.8        /1.8

11.4 = x

The sum of two integers is 61 and their difference is 1. Find the integers.
musickatia [10]

We can find this integer using a system of equations.  The first thing we look at is the first sentence.

Let's call X The first integer,

Let's call Y the second integer.


So, X+Y=61 and X-Y= 1


Using Substituion on the second equation, we get

X=Y+1

(Now we plug in Y+1 into the second equation for X)

So,

(Y+1)+Y=61

2Y=60

Y=30

So, one of the integers is 30.

Now to find the second, we go back to

X=Y+1

X=30+1

X=31.


So, the integers are 31 and 30.


Hope this helps!
