16÷4+12□4+24÷2
>
<
=
Answer:
=
Step-by-step explanation:
16 ÷ 4 + 12 ? 4 + 24 ÷ 2
Follow PEDMAS
4 + 12 ? 4 + 12 (Division first)
4 + 12 ? 4 + 12 (Addition next)
16 = 16 (They are equal)
Answer:
(=) make it a correct statement.
16÷4+12=4+24÷2
How many solutions does this linear system have?
y=-1/2x+4
one solution: (8, 0)
one solution: (0, 8)
no solution
infinite number of solutions
Answer:
The system of equations has no solution.
NO SOLUTION!
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}y=-\frac{1}{2}x+4\\ x+2y=-8\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y+\frac{1}{2}x=4\\ 2y+x=-8\end{bmatrix}[/tex]
[tex]\mathrm{Multiply\:}y+\frac{1}{2}x=4\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:2y+x=8[/tex]
[tex]\begin{bmatrix}2y+x=8\\ 2y+x=-8\end{bmatrix}[/tex]
subtracting equation 2y+x=8 from 2y+x = -8
[tex]2y+x=-8[/tex]
[tex]-[/tex]
[tex]\underline{2y+x=8}[/tex]
[tex]0=-16[/tex]
so the equations become
[tex]\begin{bmatrix}2y+x=8\\ 0=-16\end{bmatrix}[/tex]
0 = -16 is false, therefore the system of equations has no solution.
NO SOLUTION!

A letter is chosen at random from the letters of the word ASSASSINATION, then the probability that the letter chosen is a vowel is in the form of 6/2x+1, then find x.
Step-by-step explanation:
In the word "Assassination",
there are 13 letters in total and 6 vowels.
Probability of picking a vowel = 6/13.
Since 6/(2x + 1) = 6/13, 2x + 1 = 13, x = 6.

Stacy is measuring milk to make pancake batter. The recipe calls for \dfrac{3}{4} 4 3 start fraction, 3, divided by, 4, end fraction of a jug of milk. She has \dfrac{1}{4} 4 1 start fraction, 1, divided by, 4, end fraction of a jug now. How much more milk does she need?
Answer:
1/2 cup of milk
Step-by-step explanation:
Given
Total cup of milk needed = 3/4 cup of milk
Amount she has = 1/4 cup of milk
The amount of milk she needed = Total - Amount she has
Amount she needed = 3/4 - 1/4
Amount she needed = (3-1)/4
Amount she needed = 2/4
Amount she needed = 1/2
Hence she needs 1/2 cup of milk more
Help please. Question is on the picture.
Answer:
Yes; P(blue glove) = 11/20 and P(not blue glove) = 9/20
The probability of selecting a blue glove is greater than the probability of not choosing a blue glove.
See the attached diagram below
==============================================
Explanation:
There are 3 red gloves, 6 black gloves, and 11 blue gloves. So there are 3+6+11 = 20 gloves total in the drawer. The probability of picking blue is 11/20. The probability of not picking blue is 9/20 since we had 3red+6black = 9 gloves that are not blue. Or you could note that 11/20 + 9/20 = 20/20 = 1.
------------------
The probability of picking blue is greater than the probability of not picking blue. Oliver is likely to pick a second blue glove.
The way to see how 11/20 is larger than 9/20 is to compare the numerators. We see that 11 > 9, so that helps show 11/20 > 9/20.
You could also use your calculator to look at the decimal form of each fraction
11/20 = 0.55
9/20 = 0.45
This shows 11/20 is larger.
A recipe for a loaf of bread calls for of a cup of flour. If Milo used 12 cups of flour, how many loaves of bread did he prepare?
Answer:
12 loaves of bread
Step-by-step explanation:
If making one loaf of bread takes one cup of flour, using 12 cups you would make 12 loaves.
Answer:
18
Step-by-step explanation:
1 loaf bread calls for 2/3 of a cup of flour
he used 12 cups
12 ÷ 2/3 = 12 × 3/2 = 6×3 = 18

Answer:
θ = 85.93° (≈ 86°)
Step-by-step explanation:
arc length : 2πr = θ : 360°
7.5 : 2πr = θ : 360°
θ = (7.5 * 360°) / (2π*5) = 2700 / 31.42 = 85.93°
θ ≈ 86°

3k-2=10 whats the answer
Answer:
k = 4
Step-by-step explanation:
3k - 2 = 10
3k - 2 + 2 = 10 + 2 (adding 2 to both sides)
3k = 12
3k/3 = 12/3 (dividing both sides by 3)
k = 4

Pulling out like terms
4.1 Simplify ( -2xy3z-2 )3
Put the exponent aside and simplfy the base by pulling out like factors :
-2xy3z-2 = -2 • (xy3z+1)
Remember the 4th law of exponents : (a • b)m= am• bm
Retract the exponent and apply the 4th law to the simplified base: ( -2 • (xy3z+1) )3 = (-2)3 • (xy3z+1)3
Trying to factor as a Sum of Cubes:
4.2 Factoring: xy3z+1
Put the exponent aside, try to factor xy3z+1
Theory : A sum of two perfect cubes, a3 + b3 can be factored into :
(a+b) • (a2-ab+b2)
Proof : (a+b) • (a2-ab+b2) =
a3-a2b+ab2+ba2-b2a+b3 =
a3+(a2b-ba2)+(ab2-b2a)+b3=
a3+0+0+b3=
a3+b3
Check : 1 is the cube of 1
Check : x 1 is not a cube !!
Ruling : Binomial can not be factored as the difference of two perfect cubes
Dividing exponents:
4.3 23 divided by 22 = 2(3 - 2) = 21 = 2
Final result :
-2 • (xy3z + 1)3

Nancy wrote the expression 3x-12 to represent the relationship in the table of values.use operations to write two equivalent expressions.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
3x-12
1)
Writing the expression in an equivalent form
3x-12
Factor out common term 3
3x-12 = 3(x-4)
Thus, 3(x-4) is equivalent to 3x-12.
2)
Writing the expression in an equivalent form
3x-12
Multiply the expression by 2/2
[tex]3x-12\:=\frac{2}{2}\:\times \:\left[3x-12\right][/tex]
Therefore, [tex]\frac{2}{2}\:\times \:\left[3x-12\right][/tex] is equivalent to 3x-12.
If a factory can produce 250 desks in 5 days, how many desks will it produce in 15 days?
Answer:
750 would be ur answer
Step-by-step explanation:
happy new year!
Answer:750 desks
Step-by-step explanation: I would start by setting up an equation. 5d=250 (d means days). Then, to isolate the d, I would divide both sides of the equation by 5. I would get d=50. So there are 50 desks made daily. To find out the number of desks made in 15 days, I would just multiply both sides of the equation d=50 by 15 and I would get 15d=750. That means, there are 750 desks produced in 15 days. I hope this helps you out a bit!
