Gosh, I've done this problem before. Let's start with 13. In this problem, we're basically just skip counting. For example, in the roses row, in the second bouquet, we know we have to add 4 more flowers, so we can document 8. Continue to skip count for both. For 15, we would have about 96 more movie posters remaining, making our ratio 96:x. So, 96:x = 120:100. Therefore, x would equal 80- as 96:80 equals 120:100. If she needs 80 and already had 100, she should sell 20 posters. Hope this helped.
the lengths of nails with the following penny sizes: 3, 6, and 10
- A 3-penny nail is_5/4_inches.
- A 6-penny nail is_2_inches.
- A 10-penny nail is_3_inches.
This is further explained below.
<h3>What is the lengths of nails with the following penny sizes: 3, 6, and 10?</h3>
That is the equation solved for n.
The penny size is d, and n is the length of the nail, then:
if d = 3, we have:
n = (3 + 2)/4 = 5/4
if d = 6, then
n = (6 + 2)/4 = 2
if d = 10, then:
n = (10 + 2)/4 = 3
Thus:
A 3-penny nail is_5/4_inches.
A 6-penny nail is_2_inches.
A 10-penny nail is_3_inches.

correct choice is B
Step-by-step explanation:
If d represents the number of desks in each row and the administrators want there to be 13 less rows than the number d of desks in each row, then the number of rows is d-13.
The total number of desks in all rows is
Due to space limitations, there should be fewer than 264 students in the cafeteria. Therefore,
Answer:
C. y = 7x + 29 .
Step-by-step explanation:
First find the slope of the given line:
x - 7y = 12
7y = x - 12
y = 1/7 x - 12/7
The slope = 1/7 so the slope of the line perpendicular to this line is
- 1 / -1/7 = 7.
Finding the equation of the required line:
y - y1 = m(x - x1)
y1 = 8 , m = 7 and x1 = -3:
y - 8 = 7(x + 3)
y = 7x + 21 + 8
y = 7x + 29 answer.
