4+5 would be 9 because you add 4 and 5
x= hot dogs
y= soda
Total sold
1 x + 1 y = 87 .............1
2 x 0.50 y = 78.50 .............2
Eliminate y
multiply (1)by -0.50
Multiply (2) by 1.00
-0.50 x -0.50 y = -43.50
2 x + 0.50 y = 78.50
Add the two equations
1 x = 35.00
/ 1
x = 35.00
plug value of x in (1)
1 x + 1 y = 87
35 + y = 87
y = 87 -35
y = 52
y = 52.00
x= 35 hot dogs
y= 52 soda
Answer: -(x + 3)^2 = 3
Explanation:
-x^2 - 6x + 6 = 0
-x^2 - 6x = -6
-x^2 - 6x + 9 = -6 + 9
-(x + 3)^2 = 3
The answer to the missing value is X = 3
Answer: -5/21
Step-by-step explanation:
-3/7 & -4/6
common detonator is 42
-3/7 = -18/42 reduced to -9/21
-4/6 = -28/42 reduced to -14/21
difference between -9/21 and -14/21 = -5/21
