Juan has 35 pairs of shoes. Every week he gets rid of 3 pairs. After how many weeks
will he have less than 10 pairs of shoes?
I need the inequality
Answer: w < 9
Step-by-step explanation:
Answer:
9 weeks
Step-by-step explanation:
Divide the total pairs of shoes by how many you lose in a week and it will give you about how many weeks it'll take to get rid of all of the shoes:
35 / 3 = 11.67
Knowing your multiplication table is key for this! You will know that the best answer for this is 9 (and not 8 or 10) because...
3 x 8 = 24
3 x 9 = 27
3 x 10 = 30
Which will give you less than 10 pairs:
35 - 27 = 8
1 question. A big square is made up of 4 identical small squares the area of each small square is 25 cm A. Find the length of each side of the big square B. What is the perimeter of the big square 2. A rectangular swimming pool measures 15m by 8m it is surrounded by a path that is 2 m wide what is the area of the path?
Answer:
50cm
200cm
50cm^2
Step-by-step explanation:
The big square is divided into 4 with a side length of 25cm. 2 small square side lengths make up the big squares.
25 * 2 =
50cm
50 + 50 + 50 +50 =
200
15 +2
17
8 + 2
10
17 * 10 = 170
15 * 8 = 120
170-120 = 50
50cm^2
What are the leading coefficient, constant term and degree, if any, of the algebraic expression -7
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the degree of a certain polynomial will be the largest degree of any term.
For instance, in the polynomial 2x⁴ + 3 + 7x⁵ - 3x, the term 7x⁵ has the highest exponent of x i.e. 5. Thus, the polynomial has a degree of 5.
We also know that the coefficient of the term with the largest degree of the polynomial is called the leading coefficient of the polynomial.
For instance, in the polynomial 2x⁴ + 3 + 7x⁵ - 3x, the term 7x⁵ has the highest degree of 5. Thus, the leading coefficient of the polynomial
will be 7.
We also know that the constant term of a polynomial has the degree zero. i.e. the term which involves no variable.
For instance, in the polynomial 2x⁴ + 3 + 7x⁵ - 3x, the term 3 does not have any variable involved in it. Thus, the constant term of the polynomial
will be 3.
Coming back to the question:
Given the expression
-7
As the expression has only 1 constant term i.e. -7 which does not involve any variable, hence the expression -7 has the degree zero.As the expression does not involve any variable, so it does not have any leading coefficient.As the expression contains only 1 term i.e. -7, and the term does not involve any variable. Thus, the expression has the constant term -7.Answer:
leading coefficient: -7
constant term: -7
degree: 0

Which of the following is a true statement?
1. CM = CD
2. 2(AB) = AM
3. 2(MB) = AB
4. 1/2 (AM) = AB
Answer:
3. 2(MB) = AB
Step-by-step explanation:
1. This is not true because CM is less than CD.
2. This is not true because 2(AB) is greater than AM.
3. This is true because AB = 2(MB) or 2(AM).
4. This is not true because 1/2(AM) is less than AB.
Let's put some values on number 3 to check if it's, indeed, true.
Let's say AB's distance is 50 meters, then AM and MB should be half of it; that is: AM/MB = 25 meters. Let's check:
2(MB) = AB
2(25) = 50
50 = 50
Jason runs at a pace of 7 miles per hour and his friend runs at a pace represented by
the equation y = 6x where y is distance in miles and x is time in hours. Who runs
faster?
Answer:
Jason runs faster then his friend.
Step-by-step explanation:
Jason's speed is represented by the equation y = 7x because he runs 7 miles in an hour. If his friend's speed is represented by y = 6x, then his friend runs a total of 6 miles in an hour.

Based on the graph, which inequality is correct for a number that is to the right of -3?
A number line is shown from negative 8 to 8 at increments of 1. A circle is shown at negative 3. The entire portion of the number line to the right of negative 3 is shaded.
a
4 > −3
b
−3 > 4
c
−2 < −3
d
−3 < −6
Answer:
The inequality
[tex]4\:>\:-3[/tex]4 can is always greater than -3, so [tex]4\:>\:-3[/tex] is also correct.
Therefore, option 'a' is correct.
Step-by-step explanation:
Given the inequality
[tex]-3\:>\:4[/tex]-3 can not be greater than 4, so [tex]-3\:>\:4[/tex] is also incorrect.
Given the inequality
[tex]-2\:<\:-3[/tex]-2 can not be lesser than -3, so [tex]-2\:<\:-3[/tex] is also incorrect.
Given the inequality
[tex]-3\:<\:-6[/tex]-3 can not be lesser than -6, so [tex]-3\:<\:-6[/tex] is also incorrect.
Given the inequality
[tex]4\:>\:-3[/tex]4 can is always greater than -3, so [tex]4\:>\:-3[/tex] is also correct.
Therefore, option 'a' is correct.

14
16
52
Answer:
14
Step-by-step explanation:
33-19=14
Answer:
14; B
Step-by-step explanation:
You know that x + 19 = 33.
If you subtract 19 from both sides you get 14.
or you could think of it this way:
if you have 19 things and there is another person that has x amount, but all together you have 33 things/items. Then you have to subtract in order to figure out how many things the other person has.
And you can check your work by just adding 19 and 14 which will indeed give you 33.

A paint color requires the ratio of green paint to yellow paint to be 4 : 9. A container of this paint has 36 pints of yellow paint. How many pints of paint are in the container all together? *
Answer:
16:36
Step-by-step explanation:
If the ratio is 4:9 and yellow paint is 36 that means you have multiple 9 by a number and that number would be 4 to get 36 and you just multiply 4 by 4 which is 16 and your new ratio will be 16:36
Answer:
16
Step-by-step explanation:
If the ratio is 4:9 and there is 36 pints of yellow then it would be 4:9=x:36. 36 divided by 9 is 4 so you would multiply 4 to 4 and get 16.
