A square is a square a trapezoid is a lot weirder <span />
Answer:
x = 4
Step-by-step explanation:
If the lonely negative sign infront of the brackets is confusing, it can be rewritten as -1.
To solve, simplify by expanding then isolate x.
-8 = -( x +4)
-8 = -1 ( x +4) Distribute over brackets by changing the each term's sign
-8 = -x - 4 Start isolating x by moving everything to the other side
-8 +4 = -x -4 + 4 Add 4 to both sides so it cancels out on the right
-4 = -x
-4 = -1x <= -x is the same at -1x
-4/-1 = -x/-1 <=divide both sides by negative 1
4 = x
x = 4 <= usually we write the variable on the left side
Answer:
7
Step-by-step explanation:
The text of this expression is:
"If 3 is added to twice a number, the result is 17. Find the number"
Let's call 
the number we want to find.
Twice the number is equal to
So, if we add 3 to 2x, we get
And we know that this is equal to 17:
Now we can solve the equation to find x: first, we subtract 3 from both sides
Now we divide both sides by 2:
Answer:
this aint a question right?
Step-by-step explanation:
The first step is to figure out what to right in which order (because of the Order of Operations). The operations in this problem are addition and division. We know that because 'more' means addition and 'quotient' means division. The division should go first (before addition, because of PEMDAS). No we start making the equation. The quotient of n and 8 is n ÷ 8, and 13 more than the quotient of n and 8 is (n ÷ 8) + 13.
