Hello there!
<span>x + x + 2y - x + 3y
Answer: x + 5y
-----------------------------------------------------------------------------------------------------------------
Explanation/Work:
_______________
</span>x + x + 2y - x + 3y<span>
We must add like bases.
x + x - x
this would be x
Now, we have x + 2y + 3y
So, 2y + 3y
This would be 5y
So now we have x + 5y
This would be our answer
I hope I helped!

(One steel rod’s volume) = 3.14 x 4^2 x 20
= 1004.8cm^3
(Used steel) / (One steel rod’s volume) =
(Made steel rod’s number)
The answer is 28
Answer:
The first rate was 120
The second rate was 85
Step-by-step explanation:
r1 = x
r2 = y
10*x + 15*y = 2650
x + y = 205 Multiply this equation by 10
10x + 10y = 2050 Subtract this equation from the top equation.
10x + 15y = 2650
10x + 10y = 2050
5y = 600
y = 600/5
y = 120
x + y = 205
x + 120 = 205
x = 205 - 120
x = 85
Answer:
a 5-point star has rotational symmetry. A 5-point star is a two-dimensional polygon in the shape of a star with five points, or tips.
So symetry will have a total of 360 degrees, then if you divide it by 5 ( the number of point in the star) you will get 72 degrees each so it has 5 reflections
If you add 22.80 by the deposit which is 56.60 you will get 79.04
The answer is : 79.04
