Step-by-step explanation:
9 ≤ |4x + 7|
9 ≤ 4x + 7
9 - 7 ≤ 4x
2 ≤ 4x
2/4 ≤ x
<h2>
1/2 ≤ x</h2>
9 ≤ |4x + 7|
9 ≤ -(4x + 7)
9 ≤ -4x - 7
9 + 7 ≤ -4x
16 ≤ - 4x
16/-4 ≤ x
<h2>-
4 ≤ x </h2>
<h2>
{-4 ≤ x ≤ 1/2} </h2>
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
It is 27, hope this helps!
