Answer:
D. 7 units.
Step-by-step explanation:
The length is not altered by the 2 translations.
It is √[ (-1-6)^2 + (2-2)^2]
= 7 units.
A+b=45
a>b
a=b+7
→
b+7+b=45
2b+7=45
2b=38
b=19
a=19+7=26
22 quarters= $5.50
10 dimes= $1.00
$5.50 + $1.00 = $6.50
I just did trial and error. I started with 20 quarters and made changes until it worked.
7 miles divided by 4/7 hour
copy dot flip
7 miles * 7/4 hour
49/4 miles/ hour
d = rt
1 miles = 49/4 * t
divide each side by 49/4
1 / (49/4) = t
4/49 =t
it takes 4/49 of an hour
