19.q 20.d 21.6/7 22.6/7 23.b
Answer:
the answer is A
Step-by-step explanation:
350×3% =10.5
ans×5=21
You could say invitability or a foregone conclusion. Invitability just means "the quality of being certian to happen."
Example: "My teacher said it was invitable that she was going to give us a math test tomorrow"
City hall to post office = 6 1/2 miles = represented by f
city hall to library site = 1 1/4 miles = represented by d
library site to post office = unknown. = represented by e
City hall to library site PLUS library site to post office IS EQUAL to city hall to post office
d + e = f
1 1/4 + e = 6 1/2
find e.
e = 6 1/2 - 1 1/4
e = 13/2 - 5/4
e = (13*2)/(2*2) - 5/4
e= 26/4 - 5/4
e = (26-5)/4
e = 21/4
e = 5 1/4 distance from library site to post office.
To check:
d + e = f
1 1/4 + e = 6 1/2
1 1/4 + 5 1/4 = 6 1/2
6 2/4 = 6 1/2
6 1/2 = 6 1/2
It is less than 5.2, simply because the number is negative.
