The inequality that you can you use to find the original prices p of jackets that you can buy is p - 3 ≤ 30.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
You can use the following inequality to find the original prices p of jackets that you can buy:
p - 3 ≤ 30
Let p be the original price of the jacket you want to buy.
The coupon gives you a discount of $3 off any item, so the amount you can spend on the jacket is p - 3.
Since you can spend at most $30, we can write:
p - 3 ≤ 30
This inequality says that the original price of the jacket (p) minus the discount ($3) must be less than or equal to $30, which is the maximum amount you can spend.
Thus,
The inequality that you can you use to find the original prices p of jackets that you can buy is p - 3 ≤ 30.

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adults.The receipts for admission totaled to $1249.50. How many children and how many adults swam at the public pool that day?
Answer:
120 children and 388 adults bought tickets for the swimming pool
Explanation:
Create two simultanous equations:
Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being
c
+
a
=
508
then, you now create a second equation for the prices of the tickets.
(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected
so:
1.75
c
+
2.25
a
=
1083.00
now we still know, that
a
=
508
−
c
so we can substitute it into the second formula
1.75
c
+
2.25
(
508
−
c
)
=
1083
now its just simple algebra
1.75
c
+
1143
−
2.25
c
=
1083
60
=
0.5
c
so:
c
=
120
now we know, that 120 children went to the swimming pool.
and we still have the formula from before:
a
=
508
−
c
so
a
=
388

Answer:
Yes, it is possible
Step-by-step explanation:
It is possible because X does on the second day could be negative. It's a simple question, and you don't need to figure out the answer.
Basically, X on the second day could be a negative OR positive answer.

Scientific notation of 141700000
Answer:
1.47 * 10^8Step-by-step explanation:
Given the value 141700000, we are to express in scientific notation
The standard form is expressed as A * 10^n
A is any integer between 1 and 10
n is also any integer
141700000.= 1.47 * 10^8
Note that the decimal point was shifted back 8 times, main reason the power is 8
Solve for x and find the value of the angles please. this is geometry
Answer: x = 35
Step-by-step explanation:
The measure of ZB is (3x – 4) and the measure of
ZD is (2x - 6)". What are the measures of angles B
and D?
mZB=
mZD =
The measure of <B and <D are 110 degrees and 70 degrees
What is Circle geometry?The sum of the opposite angle of the quadrilateral within the circle is 360 degrees.
Given the following parameters
<B = 3x - 4
<D = 2x - 6
Equate both equations
<B + <D = 180
3x - 4 + 2x - 6 = 180
5x - 10 = 180
5x = 190
x = 190/5
x = 38
Determine the measure of <B and <D
<B = 3x - 4 = 3(38) - 4
<B = 110 degrees
<D = 2x - 6
<D = 2(38) - 6
<D = 76 - 6
<D = 70 degrees
Hence the measure of <B and <D are 110 degrees and 70 degrees

Answer:
[tex]x=10[/tex]
Step-by-step explanation:
Notice that all three sides of the given triangle has one tick mark.
This means that all three sides are congruent, meaning that we have an equilateral triangle.
And for equilateral triangles, all three angles are also congruent.
So:
[tex]\angle CBA=\angle BAC=\angle ACB[/tex]
Also, recall that the interior angles of a triangle is always 180. Thus:
[tex]\angle CBA+\angle BAC+\angle ACB=180[/tex]
Substitute:
[tex]\angle CBA+\angle CBA+\angle CBA=180[/tex]
Combine like terms:
[tex]3\angle CBA=180[/tex]
Substitute:
[tex]3(6x)=180[/tex]
Multiply:
[tex]18x=180[/tex]
Thus:
[tex]x=10[/tex]

A The zeros are - and -1, because f(x) = (x + 1)(2x + 5).
2
5
B The zeros are - and 1, because f(x) = (x - 1)(2x + 5).
2
C The zeros are -1 and, because f(x) = (x + 1)(2x-5).
The zeros are 1 and, because f(x) = (x - 1)(2x - 5).
9514 1404 393
Answer:
C. The zeros are -1 and 5/2, because f(x) = (x + 1)(2x-5).
Step-by-step explanation:
The zeros of the function are the values that make the factors zero. The factors need to multiply out to give the original standard-form equation.
The sign of the constant (-5) tells you the product of the constants in the factors must be -5. That is only true for choices B and C.
Additionally, the x-term needs to match the result of multiplying out the factors.
B. (x -1)(2x +5) = 2x^2 +3x -5 . . . . . . . . . wrong x-term (not -3x)
C. (x +1)(2x -5) = 2x^2 -3x -5 . . . . . . . . . matches the given f(x)
The factors of C are zero when x=-1, x=5/2.
