Step-by-step explanation:
Answer: Hamburger: $6.5
Drink ;$2
Step-by-step explanation:
Hi, we have to write an equation for each one
<em>Christoper</em>
Where :
h = price of a hamburger
d = price of a drink
<em>Wyatt:</em>
Now we have the system of equations:
5h+10d=52.50(1)
2h+9d=31 (2)
Isolating "h" from (1)
5h = 52.50 -10d
h = (52.50 -10d)/5
h = 10.5 -2d
Replacing "h" in (2)
2h+9d=31
2(10.5-2d) +9d=31
21 -4d +9d=31
-4d+9d=31-21
5d= 10
d= 10/5
d= $2
Finally, replacing d in (1)
5h+10d=52.50
5h+10(2) =52.50
5h+20=52.50
5h=52.50-20
5h=32.50
h= 32.50/5
h=$6.5
Answer:
19¢ or $0.19
Step-by-step explanation:
3.5 gallons per minute x 10=35 gallons for 1.90 so we could divide the 1.90 by 10 to get 0.19
M=30
To find this, you will multiply both sides by 5. 6*5=30
