The mean would be 92. Because you add them all up then divide by how many there are
Answer:
Step-by-step explanation:
he has 4.80 in dimes and quarters....dimes (d) are worth 0.10 and quarters (q) are worth 0.25
0.10d + 0.25q = 4.80
he has 6 more dimes then quarters
d = q + 6
====================
d = q + 6...so we sub q + 6 in for d, back into the other equation
0.10(q + 6) + 0.25q = 4.80
0.10q + 0.60 + 0.25q = 4.80
0.35q = 4.80 - 0.60
0.35q = 4.20
q = 4.20 / 0.35
q = 12 <====== there is 12 quarters
d = q + 6
d = 12 + 6
d = 18 <===== there is 18 dimes
Answer: 17 is A and 18 is B
Used a calculator to add them all up! Get some sleep hope this helps.
17) 2(3x8)+2(3x6)+2(6x8) = 180
18) 4(9x2)+2(9x9) = 234
Given :
Total money Beto have , P = $12 .
Cost per gallon , c = $3.75 .
To Find :
Ordered pair of lading number of gas to the total cost of gas includes the greatest amount of gas she can buy .
Solution :
Now , number of gallons she can buy for $12 is :
So , the greatest amount of gas she can buy with $10 is 3.2 gallons .
Therefore , the ordered pair is ( 3.2 , 12 ) .
Hence , this is the required solution .
Answer:
(s+t)-u
Step-by-step explanation:
You have to add s and t.
Since they are variables, the sum will be s+t
you then have to subtract u from s and t so, you have (s+t)-u
