Answer:
18.85 units
Step-by-step explanation:
c = 3.14 x d
Distance biked before lunch = 1
km (the number is written in mixed fraction)
⇒ Distance biked before lunch = 
Distance biked after lunch = 6
km (the number is written in mixed fraction)
⇒ Distance biked after lunch = 
We need to determine how much farther does Hallie bike after lunch than before lunch
Extra distance biked after lunch vs. before lunch =
- 
⇒ Extra distance biked after lunch vs. before lunch = 
⇒ Extra distance biked after lunch vs. before lunch = 
⇒ Extra distance biked after lunch vs. before lunch = 4
(in mixed fraction)
Hence, Hallie biked 4
km extra after lunch vs. before lunch.
That would be.... placoderm fish
Answer:
Let m be the number of muffins.
a) 4m <= 30
b) m <= 7.5, so the maximum number of muffins to buy is 7.
c) $4 × 7 = $28, so $2 will be left over.
3(v + 2) + 4 = 13
Mutiply the bracket by 3
(3)(v)= 3v
(3)(2)= 6
3v+6+4= 13
3v+10=13
Move +10 to the other side
Sign changes from +10 to -10
3v+10-10= 13-10
3v= 13-10
3v= 3
divide both sides by 3
3v/3= 3/3
v= 1
Answer : v= 1
