Answer:
The inequality to describe the problem is 15 +c >25.
We must sell more than 5 cones to make a profit
Step-by-step explanation:
From this problem, we can see that we need to sell a number of cones (c), that when added to the 15 cones that we have already sold, the result will be greater than 25.
To set up the inequality sign, we need to, first of all, know the inequality sign that we will be using. From the preceding statement, we can see that we need to sell greater than a certain number of cones.
This should tell us that we will be needing the greater-than sign (>).
The next step is to know the format the equation should take:
We have sold 15 cones; We need to sell c more to make it greater than 25.
This will be 15 +c >25.
The inequality to describe the problem is 15 +c >25.
from this, we can see that c > 5 cones.
We must sell more than 5 cones to make a profit

Answer:
3x^3 + 17x^2 + 21x - 9
Step-by-step explanation:
Use distributive property.
First distribute the 3x
3x times x^2 + 6x + 9. Distribute = 3x^3 + 18x^ 2 + 27x
Now we distribute the -1
-1 times x^2 + 6x + 9. Distribute = -x^2 -6x - 9
We Add both answers-
3x^3 + 18x^2 + 27x
+ -x^2 -6x - 9

Last year, Andrea ran about 120 kilometers during the months of March, April, and May. Estimate how many more kilometers she ran during those three months than she ran this year. Round to the nearest 1 kilometer. A 2-column table with 3 rows titled Total Distance Andrea Ran (kilometers). Column 1 has entries March, April, May. Column 2 has entries 48.7, 31.2, 35.66.
Answer:
March=49
April=31
May=36
Andrea ran about 116 km
this is about 4 km less than last year
Step-by-step explanation:
I got it right :))
Andrea ran 4 km extra last year if, and the total distance run this year is 120 km, The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.
What is subtraction?The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
Given:
Total distance run this year = 120 km,
The distance ran in this year's March, April, and May = 48.7, 31.2, and 35.66.
Calculate the total distance = 48.7 + 31.2 + 35.66
The total distance this year = 115.56 or 116 km
Calculate the difference as shown below,
Distance = 120 - 116 = 4 km,
Thus, she ran 4 km extra last year.

Answer:
see below
Step-by-step explanation:
The covers ( there are 2) are
2* .9 mm = 1.8 mm
Depending on how they are defining pages
If they are defining pages as the number of papers
400 pages at .13 =
400 *.13 = 52 mm
total = 2 covers + 400 pages
= 1.8 + 52
53.8 mm
If they are defining pages as the page numbers
Each page number is on the front and back so 400/2 = 200 pieces of paper
200 pages at .13 =
200 *.13 = 26 mm
total = 2 covers + 400 pages
= 1.8 + 26
27.8 mm
Answer:
52.8 mm thick
Step-by-step explanation:
0.9mm X 2mm90 = 1.8 mm
0.13mm X 400mm = 52 mm
1.8mm + 52mm = 53.8 mm

-4c+25+c=3c+79
Answer:
c = -9
Step-by-step explanation:
- 4c + 25 + c = 3c + 79 Combine like terms.
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c + 3c + 25 = 3c + 3c + 79
25 = 6c + 79
25 - 79 = 6c + 79 - 79
- 54 = 6c
-54/6 = 6c/6
-54/6 = c
-9 = c
There aren't 2 answers, you could have 2 answers if one of the c's was squared. Here is another way to do the math.
- 4c + 25 + c = 3c + 79
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c - 3c + 25 = 3c - 3c + 79
- 6c + 25 = 79
- 6c + 25 - 25 = 79 - 25
- 6c = 54
- 6c/- 6 = 54/- 6
c = 54/- 6
c = - 9
Answer:
-9 = c
Step-by-step explanation:
-4c+25+c=3c+79
-3c +25 =3c+79
25 = 6c +79
-54=6c
-54/6 = c
-9 = c

Simplify 1,999,999 with an exponent of 0
The value of 1,999,999 with an exponent of 0 is 1,999,999 × 10⁰
Before we can simplify with an exponent of zero, first we must understand that any number raised to the power of zero gives 1. Hence:
1,999,999 = 1,999,999 × 1
Since 1 can be expressed as 10⁰, the value becomes:
1,999,999 = 1,999,999 × 10⁰
Hence the value of 1,999,999 with an exponent of 0 is 1,999,999 × 10⁰

(-1,1) and (-2,3)
m=y2-y1/x2-x1
m=3-(1)/-2+1
m=2/-1

Sophie went to the lake with her family. First, they spent 1 1 4 hours fishing. Then, they spent twice as much time swimming. How much time did they spend fishing and swimming in all?
Answer:
The total time spent on both fishing and swimming is 3 3/4 hours
Step-by-step explanation:
Here, we are interested in knowing the total time spent on fishing and swimming.
From the question, we are made to know that the time spent fishing is 1 1/4 hours or simply 5/4 hours.
Then they spent two times of this time swimming.
The time spent swimming is thus 5/4 * 2 = 5/2 hours
So the total time spent on both swimming and fishing will be;
5/4 hours + 5/2 hours = (5 + 10)/4 = 15/4 = 3 3/4 hours

Anusha is walking on a hiking trail at a rate of Three-fourths miles in One-fourth hour. At this rate, how far will Anusha walk in an hour?
Answer:
Step-by-step explanation:
3/4 + 3/4 + 3/4 + 3/4 = 12/4 = 3. She will walk 3 miles in an hour.
The distance that Anusha covered in one hour is 3 miles
If Anusha is walking on a hiking trail at a rate of three-fourths miles in One-fourth hour, this is expressed as:
3/4 miles = 1/4 hours
We need to get the rate of Aisha that is the distance traveled in an hour
x = 1 hour
Divide both expressions
3/4x = 1/4
Cross multiply
4x = 3 * 4
4x = 12
x = 12/4
x = 3
Hence the distance that Anusha covered in one hour is 3 miles
