Answer:
Step-by-step explanation:
So since triangle jkl and wyz are similar angles j and w must equal each other, angles k and y must equal each other, and angles l and z are equal. So to find x just set 4x-13 equal to 71
4x-13=71
add 13 to both sides to cancel the -13 from the left
4x=84
and divide both sides by 4 to cancel the 4 on the left
x=21
the answer is 6.9.
When you divide a negative by a negative it is a positive

equation: y= 3x
21 is y so 21= 3x. divide by 3 so it's been 7 days
