We have two equations d=55t and d=20g
The left sides of this equations are the same than the right sides are equal too
a) 55t=20g
b) g=(55/20)t
c) t=6h => g=(55/20) *6 = 165/10=16.5 gallons
d= 55t= 55*6=330 miles or d=20g=20*16.5=330 miles
Good luck!!!
You put 3 muffins in the bag.
I found out by doing 12 ÷ 3 = 12, so it's 3
Answer:
x=6
Step-by-step explanation:
Combine like terms:
6 - 8x = -2x - 30
add -2x to both sides:
6 - 8x +2x = -30
Combine like terns:
6 - 6x = -30
subtract 6 from both sides:
-6x = -30 - 6
Combine like terms:
-6x = -36
Divide by -6 on both sides:
x=6
We need to build a system of equations:
a + b + c = 127......(1)
b - c = 13..............(2)
a - b - c = 41..........(3)
adding equations (1) and (3):-
2a = 168
a = 84
Substituting for in equation (1)-
84 + b + c = 127
b + c = 43...........(4)
Adding equations (2) and (4):-
2b = 56
b = 28
Finally from equation (2)
c = 28-13 = 15
Answer is Country a had 84 points , b had 28 points and c had 15 points.
