Answer:
$5.50 + $10.50 = $16
Step-by-step explanation:
6a + 5b = $34
2a + 3b = $16
...Solving by elimination
6a + 5b = 34
-3(2a + 3b = 16)
-4b = -14
b = 14/4 0r $3.50, cost of each pound of jelly beans.
a,cost of each pound of almonds = $2.75 %2816-+3%283.50%29%29%2F2+=+2.75

Find the prime factors of 60 by dividing by prime numbers.
Let's start with the smallest prime number 2
60/2 = 30
Divide that result over 2
30/2 = 15
We can't divide this by 2 because 15/2 = 7.5 isn't a whole number
Let's move onto 3
15/3 = 5
The result is a prime number, so we stop.
The values we divided as denominators were: {2, 2, 3}
We add the result 5 to the set to completely list all of the prime factors of 60
The prime factorization would be
60 = 2*2*3*5which is the same as saying
60 = 2^2*3*5What is the difference of 67.5 and 23.678

Fandango has movie tickets on sale for 1\2 price. You buy 2 $12 tickets and you must pay 6% sales tax. What is your total cost after discount and taxes?
Answer:
$12.72 or $25.44
Step-by-step explanation:
if he buys 2 tickets that are $12 each. half of 12 is 6 so you will have to pay 12 plus tax(6%). to find tax you would multiply 12 x .06 which would be $12.72. if it say the tickets are half off from $24 being $12 each then the answer would be $25.44. the question dosent specify that.

A cone and cylinder have the same height and their bases are congruent circles. If the volume of the cylinder is 120 cubic inches, what is the volume of the cone?
Answer:
Volume of cone = 40 in³
Step-by-step explanation:
Given:
Volume of cylinder = 120 in³
Height of cylinder = Height of cone
Radius of cylinder = Radius of cone
Find:
Volume of cone
Computation:
Volume of cylinder = πr²h = 120 in³
Volume of cone = (1/3)πr²h
So,
Volume of cone = (1/3)(120)
Volume of cone = 40 in³
solve the product of : 0.017 and 10
(( TYPE the STEPS you used to set up the problem and type your steps to solve. )) THANK YOU!!
The product of any two numbers is the result of multiplying them
You can use pencil and paper to get the job done, or use a calculator.
A shortcut is to simply move the decimal over 1 spot to the right.
This is because multiplying 0.017 and 10 is the same as 0.017*10^1, where the exponent of positive 1 means "move decimal point 1 spot to the right". This only works if you multiply by powers of 10.

Answer:
[tex]x=13[/tex]
Step-by-step explanation:
The perimeter of a rectangle is given by the formula:
[tex]P=2l+2w[/tex]
Where l is the length and w is the width.
We know that the perimeter is 80. Looking at the rectangle, we can also see that the length is 2x+3 while the width is x-2. Thus, make the substitutions:
[tex]P=2l+2w\\80=2(2x+3)+2(x-2)[/tex]
Distribute:
[tex]80=4x+6+2x-4[/tex]
Combine like terms and add:
[tex]80=6x+2[/tex]
Subtract 2 from both sides:
[tex]78=6x[/tex]
Divide both side by 6:
[tex]x=13[/tex]
Thus, the value of x is 13.

When analyzing three linear functions, Michele noticed that they all intersected at the point (5, 3). What conclusion can Michele come to about the linear function with the smallest slope?
Answer:
The linear function with the smallest slope must be multiple of one of the other two linear functions if all functions are coplanar. Otherwise, they intersect at the given point in space.
Step-by-step explanation:
A system of two linear functions with two variables have an unique solution on a given plane, as there are three linear function, it means that linear function with the smallest slope must be multiple of one of the other two linear functions.
But, if those functions are not all coplanar and have 3 variables, they intersect at the given point.

Step-by-step explanation:
I just did it hope this helps! :)
The addition property of equality and then the division property of equality is the sequence which describes the inverse operations used
for steps 2 and 3 to solve the linear equation
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given Linear equation is -1/2 (6x + 10) = 13
Minus one by two times of six x plus ten equal to thirteen
Step 1: –3x – 5 = 13
By addition property we add +5 on both the sides
Step 2: –3x = 18
By division property we divide both sides by -3
Step 3: x = –6
Hence, the addition property of equality and then the division property of equality is the sequence which describes the inverse operations used
for steps 2 and 3 to solve the linear equation

If f(x) = 2x+7 and g(x) = -3x+5, what is f(g(1))?
Answer:
[tex]f(g(1))=11[/tex]
Step-by-step explanation:
So we have the two functions:
[tex]f(x)=2x+7\text{ and } g(x)=-3x+5[/tex]
And we want to find f(g(1)).
So, let's find g(1) first:
[tex]g(x)=-3x+5[/tex]
Substitute 1 for x:
[tex]g(1)=-3(1)+5[/tex]
Simplify:
[tex]g(1)=-3+5[/tex]
Add:
[tex]g(1)=2[/tex]
So:
[tex]f(g(1))=f(2)[/tex]
Now, substitute 2 for x in f(x):
[tex]f(x)=2x+7\\f(2)=2(2)+7[/tex]
Multiply:
[tex]f(2)=4+7[/tex]
Add:
[tex]f(2)=11[/tex]
So:
[tex]f(g(1))=11[/tex]

p2-16p+48=0 Please solve this math problem
Answer:
( p - 4 ) ( p - 12 ) = 0
Step-by-step explanation:
To factor this equation, let's apply the quadratic formula.
p^2 - 16p + 48 = 0
Let a = 1, b = -16, c = 48
[-b +/- sqrt(b^2 - 4(a)(c))] / 2 (a)
[- (-16) +/- sqrt( (-16)^2 - 4(1)(48)) ] / 2 (1)
= [ 16 +/- sqrt( 256 - 192) ] / 2
= [ 16 +/- sqrt(64) ] / 2
= [16 +/- 8] / 2
p = (16 + 8) / 2 ; p = (16 - 8) / 2
p = 24 / 2 ; p = 8 / 2
p = 12 ; p = 4
Hence, this equation factors into the following:
( p - 4 ) ( p - 12 ) = 0
