12 people!
Step-by-step explanation:
each pizza is cut into 4 pieces, and there are 3 whole pizzas. 4 times 3= 12!
In expression x-2 coefficient of x is equal to one.
Let a be "a" x's coefficient.
If we put "a" to Your equation, it should be looks like:
ax-2
We know that there is only one x, so expression ax have to be equal x
Now we get
From this equation we know that coefficient x "a" is equal to 1.
Answer:
C
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(7x - 40) is an exterior angle of the triangle, then
7x - 40 = 3x + 3x - 20
7x - 40 = 6x - 20 ( subtract 6x from both sides )
x - 40 = - 20 ( add 40 to both sides )
x = 20 → C
