Answer:
x = 4
Step-by-step explanation:
We assume that the given expessions represent the measures of the alternate interior angles, so are equal.
... (4x + 12)° = 7x°
... 12 = 3x . . . . . . . divide by degrees, subtract 4x
... 4 = x . . . . . . . . . divide by 3
_____
Then the angles are 7x° = 28° = (4x+12)°.
Answer:
$6.50
Step-by-step explanation:
SET UP A SYSTEM OF EQUATIONS WHERE SANDWHICHES IS REPRESENTED BY S AND DRINKS BY D:
6S+4D = 53
4S+6D=47
ADD THEM TOGETHER
10S+10D=100
SOLVE FOR D
10D = 100 - 10S
D = 10-S
SUBSTITUTE THAT VALUE INTO ONE OF THE ORIGINAL EQUATIONS
4S + 6(10-S) = 47
4S + 60 - 6S = 47
COMBINE LIKE TERMS
-2S + 60 = 47
SUBTRACT 60 FROM BOTH SIDES
-2S = -13
DIVIDE BY -2
S = 13/2
S = $6.50
