Answer:
x=4
Step-by-step explanation:
3(x+2)=2(x+5)
opening brackets
3x+6=2x+10
3x-2x=10-6
1x=4

Answer:
(D)
Step-by-step explanation:
Slope : ( y2 - y1 )/( x2 - x1)
slope : ( -2 - 4 )/( - 3 + 4)
slope: ( -6 )/( 1 )
slope : -6
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
