Answer: Simplifying
2x + 4 + 2x + 8 + 2x + 8 = 180
Reorder the terms:
4 + 8 + 8 + 2x + 2x + 2x = 180
Combine like terms: 4 + 8 = 12
12 + 8 + 2x + 2x + 2x = 180
Combine like terms: 12 + 8 = 20
20 + 2x + 2x + 2x = 180
Combine like terms: 2x + 2x = 4x
20 + 4x + 2x = 180
Combine like terms: 4x + 2x = 6x
20 + 6x = 180
Solving
20 + 6x = 180
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20' to each side of the equation.
20 + -20 + 6x = 180 + -20
Combine like terms: 20 + -20 = 0
0 + 6x = 180 + -20
6x = 180 + -20
Combine like terms: 180 + -20 = 160
6x = 160
Divide each side by '6'.
x = 26.66666667
Simplifying
x = 26.66666667
Step-by-step explanation:
1.
7x - y = 5
Isolate y
Add y
7x = y + 5
Subtract
y = 7x - 5 2.
5x - 3y = 0
Isolate y
Add y
5x = 3y
Divide
y = 1.66x 3. v=iwh
Isolate w
Divide h
v/h = iw
Divide I
v/hi = w
Answer:
the minus sign
Step-by-step explanation:
In mathematics, the symbol for the additive opposite is the minus sign
The symbol for the multiplicative opposite is the inverse operation 1/x (I think)
So, yes, specific opposites have symbols, BUT...
Just saying "the opposite of" is too blurry to find one word that represents that.
First I'd assume each "pizza" refers to the number of pizza pies. Each pizza pie includes 8 slices. Since there are 12 team members, and each at three, therefore 36 slices total were eaten by each of the 12 team members (12x3). Since you know that 8 slices make up a pizza pie, how many pies do you need to have at least 36 slices? The answer is 5 pies (or 40 slices). So the team ate 36/40 slices or 9/10 pizzas.
