Other answers or options contains things that are not in the graph, and only the last one has the words Weight and cost of the apples. So this one is really reasonable.
Simplify 6x+7-5x to x+7 - 3 (x-1)+8(x-3)=x+7 Expand -3x+3+8x-24=x+7 Simplify -3x+3+8x-24 to 5x-21 5x-21+x+7 Add 21 to both sides 5x=x+7+21 Simplify x+7+21 to x +28 5x=x+28 Subtract x from both sides 5x-x=28 Simplify 5x-x to 4x 4x=28 Divide both sides by 4 x= Then Simplify 28/4 to 7
Because if you walk up to someone and ask them hey whats your blood pressure their most likely going to say i dont know unless they have a apple watch or something...
