The correct answer is A
EXPLANATION
We have
.
We want to solve for x so we divide through by
and reverse the sign of the inequality.
This gives us,
Firstly, you add 3 to both sides (as you've got to eliminate the -3), and this gives you;
7a=6+6a.
Then in order to get a alone, you need to subtract 6a from the right hand side (in order to counter balance) and this gives you;
1a=6
Therefore, a is equal to 6

3.2(10)+m(10)=85 this is the correct equation to find how much he walks every morning
Perpendicular = opposite sign and reciprocal slope
Make equation y= mx + b
3x + 4y = 24
4y = -3x + 24
y = -3/4x + 6
Now make slope perpendicular
Slope = 4/3
The answer would be B.
