Short Answer: D

Solution

Difference in weight = 8.68 - 6.2 = 2.48 pounds

%increase = x

6.2 * x/100 = 2.48                         Divide by 6.2 on both sides

(6.2 * x /100) ÷ 6.2 = 2.48 / 6.2    Simplify the left. Divide the right.

x / 100 = 0.4                                  Multiply both sides by 100

100 * x / 100 = 0.4 * 100                Combine

x = 40 %

Answer

The Puppy went up 40% in weight.

D because 6.2=100
6.2×1.4=8.68
so 100×1.4=140
140-100=40
so it's 40%

Find the value of x<br>​
Monica [59]

X= 130°

Step-by-step explanation:

From E, draw EF || AB || CD.

Now, EF || CD and CE is the transversal.

So; <DCE + <CEF = 180° [co. int. <s]

x° + <CEF = 180°

<CEF = (180° – x°).

Again, EF || AB and AE is the transversal.

So; <BAE + <AEF = 180° 01 [co. int. <s ]

105° + <AEC+ <CEF = 180°

105° +25° + (180° – x°) = 180°

x° = 130°

I hope I helped you^_^

Question
Vlada [557]

Answer:

(-6,4)

Step-by-step explanation:

You started at (-4,2)  The first number in the ordered pair moves the number left and right and the second number moved the point up and down.

We are first told to move the point 2 units to the left.  -4 is my left right number.  If I am at -4 and I go to unites to the left, I will be at -6.  My new point is now (-6,2).  Next we are told to go up 2.  The 2 number in my ordered pair tells me that I am 2 above the x axis.  Now I am going to go two more units up.  I am now at 4, so my new ordered pair after the translation is (-6,4)
