So you start with 23
for every row up you have -3
equation is
# of boxes= 23- 3x
x representing the number of rows above the bottom
# of boxes= 23- 3x=
23-3(5)= 8
5 for the top row
bottom row has 23
1 row above 23-3(x)=20
2 row above 23-3(x)= 17
3....23-3(x)= 14
4....23-3(x)=11
5...23-3(x)= 8
therefore just add all boxes each row has
23+20+17+14+11+8= 83
I hope this helps
About 3,000 books because 105 * 28 = 2940
and 2940 rounded to the nearest thousand is 3000. Hope this helps.
Answer:
k=4
Step-by-step explanation:
First, distribute the 2 on the left side
2 (k - 5) + 3k = k + 6
2*k +2*-5 +3k=k+6
2k-10+3k=k+6
Combine like terms on the left side
5k-10=k+6
Add 10 on both sides
5k=k+16
Subtract k on both sides
4k=16
Divide by 4 on both sides
k=4
Hope this helps! :)
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
To put this into slope-intercept form, you need to isolate/get the variable "y" by itself in the equation:
8x - 6y = 6 Subtract 8x on both sides
8x - 8x - 6y = 6 - 8x
-6y = -8x + 6 Divide -6 on both sides to get "y" by itself
Wow OK so the first number I came to was 72 so that's
bagels 6x12=72
apples 8x9=72
cookies 12x6=72
juice boxes 9x8=72
72/4=18 so she could make their lunch for 18 days
