Answer:
10x + 60 ; 20x
Step-by-step explanation:
Given that:
Purchase price per bracelet = $10
Cost of booth = $60
Selling price per bracelet = $20
Hence,
Let number of bracelets = x
Expense equation :
(Price per bracelet * number of bracelet) + booth fee
(10 * x) + 60
10x + 60
Income equation :
Selling price * number of bracelets
20x
The surface area for a rectangular prism is given by the formula SA = 2ab + 2bc + 2ac, where a, b, and c are the lengths of the prism. If the surface area of a rectangular prism with side c measuring 12 meters is 434 square meters and length of side a measuring the same length as side b, then what is the length of side a of the rectangular prism?
Answer:
We are given
We are also given and , which allows us to rewrite the equation as
(I substituted every "b" with "a" and every "c" with "9").
The solutions to this quadratic equation are -25 and 7. We discard -25 because a side with negative length would make no sense.
The required measure of side a of the rectangular prism is a = 9.3 meters.
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
SA = 2ab + 2bc + 2ac
434 = 2a² + 14a + 14a
434 = 2a² + 28a
2a² + 28a - 434 = 0
a² + 14a - 217 = 0
a² + 14a + 49 - 49 - 217 = 0
(a + 7)² = 266
a = 9.3 or a = -23.3
Since the negative measure of length can be neglected.
a = 9.3 = b
Thus, the required measure of side a of the rectangular prism is a = 9.3 meters.

Answer:
$88
Step-by-step explanation:
first, you find 20% of 57 which = 11.4
then subract it with 57 which looks like 57-11.4 = 45.6
= 45.6
first, you find 20% of 53 which = 10.6
then subract it with 53 which looks like 53-10.6 = 42.7
= 42.4
then you add them both which = 45.6+ 42.4= 88

I got some money for my birthday. I save and spend in the ratio 2:3. I save £32. How much money did I receive for my birthday?
Answer:
80 i think
Step-by-step explanation:
32.3=80
Step-by-step explanation:
Amount of money saved : spent = 2 : 3.
Since amount of money saved = £32,
Amount of money spent = £32 * (3/2) = £48.
Total amount of money = £32 + £48 = £80.
Therefore I received £80 for my birthday.

f f(x)=4x^(2)-9, find f(-1)
f(-1)= ?
Answer:
[tex]f(-1)=-5[/tex]
Step-by-step explanation:
Numeric Value of a Function
Given:
[tex]f(x)=4x^2-9[/tex]
It's required to find f(-1).
It can be calculated by substituting the value x=-1 in the function:
[tex]f(-1)=4(-1)^2-9[/tex]
Calculating:
[tex]f(-1)=4*1-9[/tex]

Which of the following sunds does not result in an answer of -5?
1. (-7) + (+2)
2. (-11) + (+6)
3. (-9) - (-4)
4. (-8) - (+3)
Answer:
4. (-8) - (+3)
Step-by-step explanation:
This answer does not result in an answer of -5
This subtracts -3 from -8, which gives you the answer of -11.
So, this answer is correct because it is the one that doesn't result in -5.
Answer:
Problem #4
Step-by-step explanation:
Some things to remember when doing problems like are
Double negative = positive
Double positive = positive
Negative & positive = negative
1. (-7) + (+2) 2. (-11) + (+6) 3. (-9) - (-4) 4. (-8) - (+3)
-7 + 2 -11 + 6 -9 + 4 -8 - 3

Simplify this expression. Show your work. (7x - 5) - (3x - 2)
Answer:
4x-3
Step-by-step explanation:
(7x-5) - (3x-2)
aka
(7x-5) -1 (3x-2)
first distribute the -1 into (3x-2)
-3x+2
so
(7x-5)+ -3x+2
next combine like terms
7x-3x=4x
so
4x-5+2
then
-5+2=-3
so
4x-3 would be your simplified equation

A shoe salesperson sold 20 pairs of shoes for $640. A brown pair of shoes sells for $30 and a black pair for $35. How many brown pairs were sold? A. 12 B. 14 C. 15 D. 8
Answer:
12 pairs
Step-by-step explanation:
Represent Brown with B and Black with A
So:
[tex]A + B = 20[/tex] --- Pairs sold
[tex]30B + 35A = 640[/tex] --- Amount
Required
Solve for B (the brown pairs)
Make A the subject in the first equation
[tex]A = 20 - B[/tex]
Substitute 20 - B for A in the second
[tex]30B + 35(20-B) = 640[/tex]
Open bracket
[tex]30B + 700 - 35B = 640[/tex]
Collect Like Terms
[tex]30B - 35B = 640 -700[/tex]
[tex]-5B = -60[/tex]
Divide both sides by -5
[tex]B = \frac{-60}{-5}[/tex]
[tex]B =12[/tex]
