Answer:

See below

Step-by-step explanation:

The LHS and RHS are exactly the same, so the equality is true.

The associate property of addition says that

\boxed{a+(b+c)=(a+b)+c}

In order to make the addition of fractions, the denominators should be same. So we can write three fractions as one.

\dfrac{1}{2} +\left(\dfrac{2}{3}+\dfrac{3}{4} \right )

\dfrac{1}{2} +\dfrac{2}{3}+\dfrac{3}{4}

\dfrac{1\cdot 6 }{2\cdot 6} +\dfrac{2 \cdot 4}{3 \cdot 4}+\dfrac{3 \cdot 3 }{4 \cdot 3}

\dfrac{ 6 }{12} +\dfrac{8}{12}+\dfrac{9 }{12}

\dfrac{ 23 }{12}

if there are 2040 seats in a section of a stadium, 20 seats in the first row, and 4 more seats in each row, how many rows are th
Lorico [155]


2040 = n/2(20+(n-1)4)

4080 = n(20+4n-4)

4080= 20n +4n^2 -4n

1020 = 4n + n^2

n^2 +4n -1020 =0

use common formula (can't write out so just look at answers. sorry)

which gives answers of n=-34 and n=30. since n can only be positive, n=30 so there are 30 rows. I liked that challenge
