ANSWER

a =  \frac{5}{16}

EXPLANATION

We want to find the value of a for which the binomial, 2a-1 is smaller than the value of the binomial 7-1.2a by 7.

This means that, when we subtract 2a-1 from 7-1.2a, we should get 7.

7 - 1.2a - (2a - 1) = 7

Expand:

7 - 1.2a - 2a  + 1= 7

Group similar terms:

- 1.2a - 2a = 7 - 7 - 1

- 3.2a =   - 1

Divide both sides by -3.2,

a =  \frac{ - 1}{ - 3.2}

a =  \frac{5}{16}

Your drawer has 5 pairs of black socks, 4 pairs of gray socks, 2 pairs of white socks, 1 pair of brown socks, and 1 pair of blue
Sergeeva-Olga [200]
5 pairs of black socks*2 because it’s a pair= 10 socks
4 pairs of grey socks*2=8
2 pairs of white socks*2=4
1 pair of brown socks*2=2
1 pair of blue socks*2=2
10 socks+8 socks+4 socks+2 socks+ 2 socks=26 socks in total
26/2=13+1 because you need to be sure you get one pair of socks. The smallest amount of socks you would have to grab to get at least one matching pair is 14 socks.
