Step-by-step explanation:
2(13×5)= 130
2(13×4)= 104
2(5×4)= 40
130+104+40= 274
Answer:
The solution for the given algebraic equation is 
Step-by-step explanation:
Given algebraic equation as :
( x - 8 ) + 1 = 2 ( 18 x - 1 )
Now solving the equation while opening the brackets
So, × x - × 8 + 1 = 2 × 18 x - 2
Or, 
- 
+ 1 = 36 x - 2
or, - 4 + 1 = 36 x - 2
or, - 3 = 36 x - 2
or, - 36 x = - 2 + 3
Or, - 36 x = 1
or, 
= 1
or, 
= 1
∴ 71 x = - 2
I.e x =
Hence The solution for the given algebraic equation is Answer
Question 1:
Add all the ratio numbers.
2+6+7=15
Now, divide that from 45, which is the given perimeter
45/15=3
Now, multiply the whole ratio by 3.
6:18:21
The shortest side is 6 inches.
Question 2:
Add all the ratio components.
17+16+12=45
Divide that by 180, the total degrees in a triangle.
180/45=4
Multiply that with 17 (largest ratio component).
You get 68, which is your answer.
Question 3:
(2x+7)/(3x-4) = 11/2
This proportion is quite simple and can be solved by setting the numerator equal to the numerator and the denominator equal to the denominator.
2x+7=11
3x-4=2
If you solve both of these, the value of x is 2.
That's your answer.
(Note: this is only a special case where you can do this)
Hope this helps! :)
