Answer:
18 gallons
Step-by-step explanation:
divide 300 by 15 you 150 or 15 again then add 1 gallon per every twenty miles
thus your answer is 18 gallons of gas
300(miles)/15(gallons) = 20 miles in 1 gallon
360(miles)/20(miles) = 18 gallons
4x+9y=28
-4x-y=-28
8y=0
divide both side by 8
y=0
solve for X in equation 1
4(X)-9(0)=28
4x-0=28
4x =28
divide both side by 4
4x/4=28/4
X= 7
y=0,x=7
2628.15
1909.15+ 1437.99/2=2628.15
75.7 rounded to 76
Explaination:
13 * 2 = 26
26 / 7 = 3.71
3.71 - 10 = -6.28
-6.28 + 82 = 75.7
Rounded 75.7 = 76
