Step-by-step explanation:
3x + 2y = 7
y = -3x + 11
Solve the system of equation using substitution.
Substitute the y in the first equation by its value presented in the 2nd equation.
3x + 2y = 7
3x + 2(-3x + 11) = 7
3x - 6x + 22 = 7
-3x + 22 = 7
-3x = 7 - 22
-3x = -15
-3x/-3 = -15/-3
x = 5
Substitute x in the 2nd equation by its computed value. x = 5
y = -3x + 11
y = -3(5) + 11
y = -15 + 11
y = -4
x = 5 ; y = -4
Substitute x and y in the 1st equation with its corresponding values
3x + 2y = 7
3(5) + 2(-4) = 7
15 - 8 = 7
7 = 7
I believe 3648 gallons of gasoline
13 you had to round 12/5 to a whole :) :) :) :)
We have that
poster---------------- > 28 in X 32 in
1 in-------------------------------- >0.0833333 ft
28 in------------ > 28*.0833333=2.33 ft
32 in------------ > 32*.0833333=2.67 ft
Let
D---------------- >distance from the ceiling to the top of the poster
D=(9- <span>5 1/2 -2.67/2)=(9-5.5-1.335)=2.165 ft
the answer is 2.165 ft
