The lcm of 120 and n is 2520. Find the smallest value of n.
Please explain the answer. Thank you.
Answer: The smallest value of n is:
n = 21
Step-by-step explanation:
We know that the LCM (least common multiple) between 120 and n is 2520.
We want to find the smallest value of n.
The smallest value of n will be such that n does not share any prime number with 120, then the greatest common factor between 120 and n is 1.
Remember that the LCM between A and B is:
LCM(A, B) = A*B/(GCM(A, B))
Then if the greatest common factor between A and B is 1, we will have:
LCM(A, B) = A*B
Then if the greatest common factor between 120 and n is 1, we have that:
LCM(120, n) = 120*n = 2520
then:
n = 2520/120 = 21
The smallest value of n is n = 21.
If the time is 2:12 pm then how many minutes ago did the time turn to noon
Answer:
132min (mark brainliest?)
Step-by-step explanation:
noon = 12pm
2:12pm - 12pm = 2 hours and 12 min
2 hours *( 60 min) = 120 min
120 min + 12 min = 132 min
Which of the following illustrates the Distributive Property?
A. 3(2x + 4) = 5x + 4
B. 3(2x + 4) = 5x + 7
C. 3(2x + 4) = 6x + 4
D. 3(2x + 4) = 6x + 12
Answer:
I think that the correct answer is D 3(2x + 4) = 6x + 12
3(2x + 4) = 6x + 12 illustrates the Distributive Property. Correct option is D.
The Distributive Property states that when you multiply a number by a sum or difference inside parentheses, you distribute the multiplication across each term inside the parentheses.
The correct illustration of the Distributive Property among the given options is:
D. 3(2x + 4) = 6x + 12
This is because when you distribute 3 across 2x and 4, you get 6x for the first term (3 * 2x) and 12 for the second term (3 * 4), resulting in 6x + 12.

What is the value of x?
Answer:
Step-by-step explanation:
Step One
Find the supplement of both exterior angles. They both have angles that add with them to make 180 degrees.
x + 105 = 180 Subtract 105 from both sides
x = 180 - 105
x = 75
y + 148 = 180 Subtract 148 from both sides
y = 180 - 148
y = 32
Step Two
There are two ways to conclude the problem. You could find the value of the 3rd angle of the triangle, or you could notice that x is going to be the sum of the 2 angles you just found. These two angles are called the remote interior angle.
Method One
x = 32 + 75
x = 107
Method Two
32 + 75 + y = 180
107 + y = 180
y = 180 - 107
y = 73
The sum of x + 73 = 180
x = 180 - 73
x = 107
Jenny and Laura share £30 in the ratio of 3:2 work out how much money jenny gets
Answer:
Jenny gets €18.
Step-by-step explanation:
Jenny gets 3 of every Laura's 2. First you add together both numbers in the ratio. 3+2=5. Then you divide the constant, 30, by the sum, 5. 30/5=6. Then you multiply each number of the ratio by the quotient. 3 x 6=18.
determine if the point (4,7) is a solution to the system of equations shown below. Justify your yes/no answer.
y=2x-1 and y=1/2x+5
Answer:
The point (4,7) is a solution to the system of equations.
Please also check the attached graph.
Step-by-step explanation:
Given the system of equations
[tex]y=2x-1[/tex]
[tex]y=\frac{1}{2}x+5[/tex]
Let us solve the system of equations using the elimination method
[tex]\begin{bmatrix}y=2x-1\\ y=\frac{1}{2}x+5\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y-2x=-1\\ y-\frac{1}{2}x=5\end{bmatrix}[/tex]
subtracting the equations
[tex]y-\frac{1}{2}x=5[/tex]
[tex]-[/tex]
[tex]\underline{y-2x=-1}[/tex]
[tex]\frac{3}{2}x=6[/tex]
now solving [tex]\frac{3}{2}x=6[/tex] for x
[tex]\frac{3}{2}x=6[/tex]
Multiply both sides by 2
[tex]2\cdot \frac{3}{2}x=6\cdot \:2[/tex]
Simplify
[tex]3x=12[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{12}{3}[/tex]
Simplify
[tex]x=4[/tex]
For [tex]y-2x=-1[/tex] plug in x = 4
[tex]y-2\cdot \:4=-1[/tex]
[tex]y-8=-1[/tex]
Add 8 to both sides
[tex]y-8+8=-1+8[/tex]
Simplify
[tex]y=7[/tex]
Therefore, the solution to the system of equations is:
(x, y) = (4, 7)
Hence, the point (4,7) is a solution to the system of equations.

Answer:
"?" = 3
Step-by-step explanation:
The answer can be gotten by subtracting 4 from 7. The 4 is the exponent in (4a^4b), and the 7 is the exponent in 16a^7b. So:
7 - 4 = 3
Therefore, the "?" = 3
Hope this helps :)
Answer:
?=3
Step-by-step explanation:
Okay so with exponents, when multiplying exponents with the same base, you add them.
In your case, we have a^? * a^4=a^7 (this is the only part you need to solve)
so ?+4=7
?=7-4=3
