Answer:
x=13
Step-by-step explanation:
Well, the triangle is always equal to 180 degrees in total. Lets remember that x will always be the same in every equation.
So, (5x-11) x (2x+20) x (11x-63) = 180.
Now, take away the parenthesis and add up all the like terms.
This should = 18x-54 = 180.
Now solve like you regularly would. Add 54 on both sides which equals,
18x=234. Now, divide 18 on both sides.
x = 13.
Hope this helps.
Answer:

Step-by-step explanation:
To convert from feet to yards, divide by the value 3.
So we need have to understand that if we were to solve this, our answer would be 7 less than 'p' with that information we get p-7.
Answer:
4/5 - 1/4
Step-by-step explanation:
4/5 =0.8
1/4=0.25
⇒0.8 - 0.25 = 0.55 (decimal form)
⇒4/5 - 1/4 = 11/20 (exact form-fraction)
Answer:
A
Step-by-step explanation:
The inverses of functions are basically the Xs and Ys swapped. For example, the inverse of (2,-3) is (-3,2).
Thus, the inverse of (-2,4), (3,2), and (-6,10) will be (4,-2), (2,3), and (10,-6).
the answer is A.
