Brainliest please!
The question asks us to find the value of

such that

. First, we subtract

from both sides, which gives us

. Now, we need to express the equation as

and

. When we do this, we get

. After simplifying, we get

. All that's left now is factoring and simplifying, giving us

as an answer. Hope this helped and have a phenomenal day!
There are 7 dimes out of 24 total coins in the collection put 7/24 in a calculator and you should get .2916 repeating
<span>Let Ah be Annie's hour of travel in 1 day and Bh be
Brian's hour
to get Brian's hour of travel:
Ah + Bh = 20
5 (Bh +2 ) + Bh= 20
5 Bh + 10 + Bh=20
6 Bh = 20 - 10
<u>6Bh</u> = <u>10</u>
6 6</span>
Bh =1.66
To get Ah of travel 1 day
Ah = 5 (Bh + 2)
<span> = 5 (1.66 +
2) </span>
<span>
= 5 ( 3.66 )</span>
Ah = 18.30
Checking:
Ah + Bh =20
<span>
18.30 + 1.66 = 20
</span><span>19.96 = 20</span>
<span>
20 = 20</span>
(19.96 is rounded off)
