Answer:
25 Should be the answer tell me if im wrong!
Step-by-step explanation:
Answer:
x=
2/7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7/3x 3/7=2/3(3/7)
so 2/7
I got 39 tables.
134+167=301
301/7=43
Total amount of people =344
344/9=38.222 which you would round to 39 tables
6x^2 - 8 = 4x^2 + 7x
6x^2 - 4x^2 - 7x - 8 = 0
2x^2 - 7x - 8 = 0
discriminant = b^2 - 4ac; where a = 2, b = -7 and c = -8
d = (-7)^2 - 4(2)(-8)
d = 49 + 64
d = 113
the discriminant is greater than zero, so there are two real roots
