It is the third option 16x+9=4x
There is no way to tell because there is no value for x and y. However just looking at the picture, I’m guessing m is around 45 degrees.
4.
a+5=-5a+5
Subtract 5 from both sides
a=-5a
Subtract a from both sides
0=-6a
Divide both sidesby -6
0=a
Final answer: a=0
6.
p-1=5p+3
Add 1 to both sides
p=5p+4
Subtract 5p from both sides
-4p=4
Divide both sides by -4
p=-1
Final answer: p=-1
The answer is D. First add 2k, then divide by a, the subtract x, then divide by -1
3/10 out of 40
= 3/10 * 40
= 3 * 4
= 12
