Answer:
1. 10 weeks
Step-by-step explanation:
Apparently, we want to find the number of weeks (w) that Kaitlyn must save $6 in order to have a total of $60.
... $6 × w = $60
Divide by $6 to get ...
... w = $60/$6 = 10
Kaitlyn must save for 10 weeks (if she starts with a balance of 0).

<em>Comment on the problem statement</em>
The problem reads like we came in somewhere in the middle of it. We don't know what other steps you've been asked to perform, or any of the details of the problem you're asked to solve. We don't have Kaitllyn's initial balance, for example, which is essential to determining how long she must save. (If Kaitlyn's initial balance is $33, for example, she must only save for 4.5 weeks.)

Answer:
y = -3x -1
Step-by-step explanation:
We can write the equation in slope-intercept form if we know the slope and the y-intercept.
The slope is ...
m = "rise"/"run" = (change in y)/(change in x)
We can see that the line passes through grid intersections at (x, y) = (0, -1) and at (1, -4). Between these two points, the change in y is (-4 -(-1)) = -3, and the change in x is (1 -0) = 1. Then the slope is ...
m = -3/1 = -3
One of the points we just used is the point where the line crosses the y-axis, at the y-intercept of -1. So, with slope -3 and y-intercept -1, the equation of the line is ...
y = mx +b . . . . . . slope m and y-intercept b
y = -3x -1
The answer would be: -a - 5
<span>You'd do 729÷3=243, then 243÷3=81. The number is 81. I hope this helps!</span>
