Answer:
The answer is $9.67.
Step-by-step explanation:
Notebooks: 5 * 1.29 = 6.45
Pens: 2 * 1.19 = 2.38
Pencils: 12 * 0.05 = 0.60
Erasers: 6 * 0.15 = 0.90
Total: 6.45 + 2.38 + 0.60 + 0.90 = 10.33
Change: 20 - 10.33 = 9.67

If i roll 2 dice what is the probability that neither of them are prime nor even?
Answer:
There are 3 prime numbers shown on the die: 2, 3 and 5. The probability of showing a prime number on a single die is 1/2, hence the probability of not showing a prime number is also 1/2. Total possible outcomes when two dice are rolled = 6*6 = 36. Total possible outcomes when two dice are rolled = 6*6 = 36.

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of EqualityStep-by-step explanation:
Step 1: Define
3x - y = 18
y = 27
Step 2: Solve for x
Substitute in y: 3x - 27 = 18Isolate x term: 3x = 45Isolate x: x = 15Answer:
15
Step-by-step explanation:
3x - y = 18
Insert the value of y in the equation.
3x - 27 = 18
Shift -27 to the other side of the equation.
3x = 18 + 27
3x = 45
x = 45 ÷ 3
x = 15
So please check if your options and the equation are correct.
What is the answer to 5 divided by 2/7
Answer:
17 1/2
Step-by-step explanation:
To divide a whole number and a fraction, write the whole number as a fraction (in this case, 5 becomes 5/1). Then, change the division symbol to a multiplication symbol. After that, you flip the second number and multiply. As you can see, you get 35/2 as the answer. To simplify that, divide 35 by 2. The answer becomes the whole number, the divisor becomes the denominator, and the remainder becomes the numerator. That means our simplified answer is 17 1/2.

x min = 420 cartons
do 420 times 1 it gives u 420 then divide by 6.

The sum of 3 consecutive even
numbers is 78.
Write the variable representation for each of
the three numbers in this sequence.
Answer:
The variable representation is x, x+2 and x+4 for this sequence.
Step-by-step explanation:
Given that:
The sum of 3 consecutive even numbers is 78.
Let,
The first even number is represented by x.
As the numbers are consecutive, thus,
First even number = x
Second even number = x+2
Third even number = x+4
Hence,
The variable representation is x, x+2 and x+4 for this sequence.
(10, 7); 5х - бу = 18
Answer: See explanation
Step-by-step explanation:
x = 10
y = 7
5x - 6y = 18
5 (10) - 6 (7) = 18
50 - 42 = 18
8 ≠ 18

round 5,816 to the nearest hundred
Answer:
5800
Step-by-step explanation:
that is to the nearest hundred
Answer:
5,800
Step-by-step explanation:
In 5,816. the number in the hundred place is the 8. The rule in rounding is 5 and above goes up, under 5 stay the same. The number after the 8 is the 1 and 1 is less than 5, so stays the same. So the 5,816 rounded to the hundred place is 5,800.

q⁸/16p¹²Step-by-step explanation:
Use of formulas:
(a/b)⁻ⁿ = (b/a)ⁿ(aᵇ)ⁿ = aᵇⁿSimplifying
(2p³/q²)⁻⁴ =(q²/2p³)⁴ =(q²)⁴/(2p³)⁴ =q⁸/2⁴p¹² =q⁸/16p¹²Answer:
[tex] { (\frac{2 {p}^{3} }{ {q}^{2} }) }^{( - 4)} = \frac{{2}^{(-4)} {p}^{(3 \times ( - 4))} }{ {q}^{(2 \times ( - 4))} } = \frac{ {p}^{ (- 12)} }{16 {q}^{( - 8)} }=\boxed{\frac{ {q}^{8} }{ 16{p}^{12} }} \\ [/tex]

Answer:
tanP = [tex]\frac{20}{21}[/tex] , tanQ = [tex]\frac{21}{20}[/tex]
Step-by-step explanation:
tanP = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{QR}{PR}[/tex] = [tex]\frac{20}{21}[/tex]
tanQ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{PR}{QR}[/tex] = [tex]\frac{21}{20}[/tex]

for the equation 2(4x+10)=8x+k what value of k will create infineltly many solutions please help
Answer:
The value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
Step-by-step explanation:
Given the expression
[tex]2(4x+10)=8x+k[/tex]
solving
[tex]2(4x+10)=8x+k[/tex]
[tex]8x+20 = 8x+k[/tex]
We know that the equations with infinitely many solutions have the same expressions on both sides
It means the value of k can be determined by further simplifying such as
[tex]8x+20 = 8x+k[/tex]
8x+20-8x = k
20 = k
Therefore, the value of k = 20 for equation 2(4x+10)=8x+k to have infinitely many solutions.
VERIFICATION:
Given
[tex]2(4x+10)=8x+k[/tex]
[tex]8x+20 = 8x+k[/tex]
Put k = 20 in the equation
[tex]8x+20 = 8x+20[/tex]
[tex]8x+20 - 8x+20 = 0[/tex]
[tex]0 = 0[/tex]
equations with infinitely many solutions have the same expressions on both sides.
This means the statement is always true.

Which equation represents a direct linear variation?
A) 7=x+2
B) y=1/2x
C) y=1/x
D) 7=x^2
Answer:
B
Step-by-step explanation:
The equation representing direct linear variation is
y = kx ← k is the constant of variation
The only equation in this form is
y = [tex]\frac{1}{2}[/tex] x ( with k = [tex]\frac{1}{2}[/tex] )
Can you also explain it? Use the distributive property to simplify the expression.
4 (1a + b – 6)
Answer:
4a + 4b - 24
Step-by-step explanation:
You first start off by giving (multiplying) 4 to everything that's in the parenthesis.
Second you multiply:
4 x 1a = 4a
4 x b = 4b (also remember that a variable by its self is just 1)
4 x -6 = -24
Lastly you put it together:
4a + 4b - 24
For the -24 you can either do it the way I did or this way -> (-24) but teachers will look mostly for -24 way. But use whichever one is easier for you :)
Hope this helps!

Answer:
Here are the steps required for Dividing by a Polynomial Containing More Than One Term (Long Division):
Step 1: Make sure the polynomial is written in descending order. If any terms are missing, use a zero to fill in the missing term (this will help with the spacing).
Step 2: Divide the term with the highest power inside the division symbol by the term with the highest power outside the division symbol.
Step 3: Multiply (or distribute) the answer obtained in the previous step by the polynomial in front of the division symbol.
Step 4: Subtract and bring down the next term.
Step 5: Repeat Steps 2, 3, and 4 until there are no more terms to bring down.
Step 6: Write the final answer. The term remaining after the last subtract step is the remainder and must be written as a fraction in the final answer.
