This is a triangle.  The interior angles of a triangle always add up to 180 degrees.  Thus, write an equation representing the sum of the given angles, with "180 degrees" on the right side.

4x-1    +    8x+2     +   71  =   180 degrees.  

Solve for x!

What is if 40% of a number is 56 what was the original number ,, can u show me how to do it?
ASHA 777 [7]
The number is assumed to be x

x of 40% = 56
x * (40/100) = 56
x = 5600 / 40
x = 140

How do you solve this
tekilochka [14]

Answer:

<h2>A</h2>

Step-by-step explanation:

gradient = (-3+2)/(0-3)

gradient = 1/3

slope intercept form : y = mx + b

m is the gradient which we have found to be 1/3

b is the y intercept that can either be -2 or - 3 (both the y coordinates)

therefore the equation would be y = 1/3 x - 3    (A)

hope this helps :)
