<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)
15 miles per hour is the answer because 2/1/2 divided by 1/6 is 15
Answer:
7/21
Step-by-step explanation:
Hey there! :)
-(3x)² + 3 = -6
Simplify.
-(9x²) + 3 = -6
Simplify.
-9x² + 3 = -6
Subtract 3 from both sides.
-9x² = -6 - 3
Simplify.
-9x² = -9
Divide -9 from both sides.
-9x² ÷ -9 = -9 ÷ -9
Simplify.
x² = 1
So, x = 1 OR x = -1
~Hope I helped!~
