Answer:
3x-9 is the answer on edgenuity:)
Step-by-step explanation:
First, use distributive property:
5(2r+6)-12r <em>The original expression; multiply 5 by 2r, and 5 by 6.</em>
10r+30-12r <em>Keep the -12r, just add it on to the end of the number(s) you found</em>
Next, use communitive property:
10r+30-12r <em>What we found in the previous step</em>
-2r+30 <em>Combine the like terms; 10r-12r=-2r, then place the 30 at the end</em>
Done! Your answer is -2r+30.
Hope that helps!
Hi there!
Here is the step by step explanation to solving this problem :
20% of $1,049
20% is the same thing as 0.2 & the word "of" is the same thing as a multiplication sign :
0.2 × 1,049 = $209.80
1,049 - 209.80 = $839.20 = price after discount
4.25% is the same thing as 0.0425 :
0.0425 × 839.20 ≅ $35.67
839.20 + 35.67 = $874.87
The total cost is : $874.87
There you go! I really hope this helped, if there's anything just let me know! :)
<span>If an image of a triangle is congruent to the pre-image, then the scale factor of the dilation must be n = 1.
Hope it helps!
