Leah is mixing peanut butter candy (p) that sells for $3.60 per pound with chocolate candy (c) that sells for $2.00 per pound. She needs 50 pounds of the mixture to sell in her store for $2.16 per pound. Which system of linear equations can Leah use to determine the number of pounds of each candy to use?
Answer:
45 pounds of the chocolate candy and 5 pounds of the peanut butter candy.
Step-by-step explanation:
let's define the variables:
p = pounds of peanut butter candy she uses
c = pounds of chocolate candy she uses.
We know that she wants to have a total of 50 pounds of the mixture, then we will have that:
p + c = 50
We also want that these 50 pounds sell for $2.16 per pound.
Then we must have that the price for the candies in the mixture must be equal to the desired price, we can write this as:
p*$3.60 + c*$2.00 = (50 )*($2.16 )
Then we have the system of equations:
p + c = 50
p*$3.60 + c*$2.00 = (50)*($2.16) = $108
To solve this, we first need to isolate one of the variables in one of the equations. I will isolate p in the first equation to get:
p = 50 - c
Now we can replace this in the other equation to get:
(50 - c)*$3.60 + c*$2.00 = $108
Now we can solve this for c.
$180 - c*$3.60 + c*$2.00 = $108
$180 - c*$1.60 = $108
$180 - $108 = c*$1.60
$72 = c*$1.60
$72/$1.60 = c = 45
This means that she should use 45 lb of the chocolate candy, and using the equation:
p + c = 50
p + 45 = 50
p = 50 - 45 = 5
p = 5
She should use 5 lb of the peanut butter candy.

Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative. Is Awad’s claim true or false? Explain your reasoning. If it is true, give an example to support his claim. If it is false, give a counterexample. Explain your reasoning..
Answer:
False
Step-by-step explanation:
False, because whenever you subtract a negative number, you always end up adding because two negatives make a positive. Lets say n is 4 and m is -3, 4-(-3) is going to turn into 4+3=7.
The Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative.
The above claim is false because subtracting a negative integer always results in an addition because two negatives equal a positive.
For example, n is 6 and m is -2; 6 -(-2) will equal 6 + 2 = 8.
Hence, the Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.

Use substitution to solve the
following system of equations.
9x + 5y = 32 AND y = -3x + 4
Answer:
x = -2
y = 10
Step-by-step explanation:
Since they already gave y as -3x +4, you will then have to substitute that amount into the formula
9x + 5y = 32
By doing that you get
9x +5(-3x+4) = 32
9x -15x +20 = 32
Then, you ill take 20 to the other side to subtract 32, which will get you
-6x = 12
Then, you will get x = -2
Then substitute that for the equation
y = -3x + 4
You will get
y = -3(-2) + 4,
You will get y as 10
SO then your final answer is x = -2, y = 10

A 25-foot ladder is leaned against a wall. If the base of the ladder is 7 feet from the wall, how high up the wall will the ladder reach?
Answer:
24ft
Step-by-step explanation:
Pythagorean Theorem!!
[tex]a^2 + b^2 = c^2[/tex]
------------------------
In this case, the ladder is c, and the base is b.
------------------------
Plug the numbers in the formula.
[tex]a^2 + 7^2 = 25^2[/tex]
------------------------
Solve.
[tex]a^2 + 49 = 625[/tex]
[tex]a^2 -49 = 625 - 49[/tex]
[tex]a^2 = 576[/tex]
[tex]\sqrt{a^2} = \sqrt{576}[/tex]

Find the volume of a cone with a height of 6cm and a base radius of 4cm. Use the value 3.14 for π, and do not do any rounding.
Answer:
100.48 cm³
Step-by-step explanation:
Volume of a cone, V = 1/3 * pi * r² * h
Radius, r = 4 cm ; h = 6cm
V = 1/3 * 3.14 * 4² * 6
V = 1/3 * 3.14 * 16 * 6
V = 3.14 * 16 * 2
V = 3.14 * 32
V = 100.48 cm³
Hence, the volume of the cone is 100.48 cm³

After 20,% discount a mobile set is bought at rupees 13920 find the marked price of the mobile set. Maths question
Step-by-step explanation:
First of all, let us lay down the clues;
●There is a 20% discount on the mobile set.
●The price after the discount is Rs 13 920
●We need to find the original price.ie.(100% stands for original price)
Now let's start;As there is a 20% Discount on the m.Set, we need to find the exact percentage decrease.
So,
100%-20%= 80%
Now let's do Direct Proportion,
80%= Rs 13 920
1%= 13 920/80
100%= 13 920/80*100=Rs 17 400

HELP IM DOIN A MATH TEST AND IM STUCK!!!!! Tim knows the volume In bass area of a wooden chest that is in the shape of a rectangular prism. If the volume is 5/24 Of a cubic unit and the base area is 1/5 of a square unit, What is the height of the chest?
Answer:
Height is 1 1/24 unit.
Step-by-step explanation:
Given:
volume = 5/24 unit³
base area = 1/5 unit²
Rectangular prism:
volume = length * width * height
base area = length * width
Volume = base area * height
height = volume / base area
h = 5/24 ÷ 1/5
h = 5/24 * 5/1 = 5*5 /24*1 = 25/24 = 1 1/24 unit
(hope this helps can i plz have brainlist :D hehe)
hi can someone help me with this?
Answer:
h = 4.5 units
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 6.75 and b = 3 , then
[tex]\frac{1}{2}[/tex] × 3h = 6.75
1.5h = 6.75 ( divide both sides by 1.5 )
h = 4.5
we have
base [b]=3 units
height [h]=x units
area of triangle =6.75 square units
we have
area of triangle =1/2 b×h
6.75 square units =1/2×3×x
x=6.75×2/3=4.5units
so height is 4.5 units.

Answer:
131°
Step-by-step explanation:
(disclaimer this isn't necessarily right, please don't come at me if this is wrong)
So the only we have is the measurement of angle H, which is 49°. So we're going to assume that they're all equal, cause I don't know what else to do, so:
180° - 49° = 131°
So, I think that angle F is 131°

Answer:
4. 12c(3a^5b - 1)
Step-by-step explanation:
Greatest common factor of 36 and 12: 12
There are variables a^5b on left term but not on right term, so there is no common factor of a or b.
Greatest common factor of c and c: c
Common factor: 12c
36a^5bc / 12c = 3a^5b
-12c / 12c = -1
Answer: 36a^5bc - 12c = 12c(3a^5b - 1)
