8 ( 20divided by 15=1.333 then times that by6)
And
60 (triple 15)
Answer:
Step-by-step explanation:
Given:
Cost of L = $5
Cost of S = $3
No. of drinks sold = 60 drinks
Total sale = $220
Solution:
L + S = 60 - (1) (multiplying by 3)
5L + 3S = 220 - (2)
(-)3L +(-) 3S = (-)180 - (1)
2L = 40
L = 40 / 2
L = 20 Large drinks
20 + S = 60
S = 60 - 20
S = 40 small drinks
Therefore, 20 large drinks and 40 small drinks

5 if 1 zero follow the decimal point
790 :- 2 significant figures
0.0391 :- 3 significant figures ( follow 3 rule)
81.05 :- 4 significant figures ( rule 4)
0.000001 :- 1 significant figure
8546 :- 4 significant figures
79.0 :- 3 significant ( rule 5)
X=4 or X=-4 because 4(4)^2 does =64
