What is the lowest common multiple of 12 and 15?
Answer:
60
Step-by-step explanation:
LCM of 12 and 15
First Method: Listing the multiples
First, write the common multiples of all three numbers.
Common Multiples of 12: 12,24,36,48,60,72,….
Common Multiples of 15: 15, 30, 45, 60, 75,…
Hence, the Least common multiple of 12 and 15 is 60.
Second method: By prime factorisation
Let us write the prime factors of the two numbers individually.
12 = 2 x 2 x 3
15= 3 x 5
Multiply each factor the maximum number of times it occurs in either number
= 2 X 2 X 3 X 5
= 60
LCM of 12 and 15= 60
Answer
LCM of 12 and 15= 60
Hope this helps :)
Answer:
60
Step-by-step explanation:
we have to use prime factorisation method to obtain the answer.
12 and 15 have LCM 60.

Step-by-step explanation:
A sailboat with a sick passenger abroad is following a parabolic path given by the equation = − 2 +2 + 8.
The boat’s captain sent out a distress signal. A speedboat is trying to catch the sailboat to provide medical aid and is on a path given by the linear equation y=- x+8. Besides the y-intercept (starting location) where do the paths of the two boats cross (for each graph you must plot at least 3 points each and give answer in coordinate pair notation)?

Kailey is thinking of two numbers. The larger number is equal to twice the smaller increased by 12. Two times the smaller number plus three times the larger is equal to 100. Let x = smaller number and y = larger number. What is the first equation in the system? Do not put spaces in your answer.
Answer:
y=2x+12
Step-by-step explanation:
We first double the smaller number (2x) and then increased it by 12 (+12), this makes the larger number y.

A. g(x) = f(x)+5
B. g(x) = f(x+5)
C. g(x) = f(x)-5
D. g(x) = f(x-5)
Answer:
-3 and 2Step-by-step explanation:
Te solutions of f(x) = g(x) are x-coordinates of points of intercept of the graphs.
Points of intercept are (-3, -8) and (2, -3)
So the solutions are: -3 and 2

In order to solve the system of equations below, Harvey multiplies each equation by a constant to eliminate the x
terms.
7x+ 3y = 5
2x+5v=-11
What are the resulting equations?
Answer:
14x + 6y = 10
14x + 35y = -77
Step-by-step explanation:
Multiply the top one by 2
14x + 6y = 10
Multiply the bottom one by 7
14x + 35y = -77
His next step is to subtract. You could have done this by multiplying the top one by -2
-14x - 6y = - 10
14x + 35y = -77 Now all you need do is add. The question now becomes what do you do? What answer do you give? I think the expected answer is the top two equations, but if I was actually doing the problem, I'd use the bottom 2.
Answer:
A) 14x + 6y = 10
-14x - 35y = 77
Step-by-step explanation:
multiple the first equation by 2 and the second equation by -7
2( 7x + 3y = 5)
-7( 2x + 5y = -11)
14x + 6y = 10
-14x - 35y = 77

A whale can stay underwater 7 times as long as x minutes more than a platypus can. Write an equation that states the relationship of the minutes these two mammals can stay underwater
Answer:
Step-by-step explanation:
Using the information provided we can create the following two equations each of which calculates the total number of minutes that the whale (w) or the platypus (p) can stay underwater. In order to solve each, you would need the value of at least 1 of the mammals.
w = 7 * (p+x)
p = (w / 7) - x
The w in these equations represents the number of minutes the whale can stay underwater while the p represents the number of minutes that the platypus can stay underwater.

Choose SSS, SAS, or AA to prove the triangles are similar.
A. SSS
B. SAS
C. AA
Answer :As, all sides are given so we can use SSS to prove the triangles are similar.
So, correct option is A.
Explanation :Given : Sides of 1st triangle = 24, 32 and 40Sides of 2nd triangle = 27, 36 and 45To Prove :Triangles are similarProof :As, all three sides are given so let's check ratio of all three sides.

Find the slope of the line y= -8/5x + 2
Step-by-step explanation:
Given
y = - 8 /5 x + 2
Comparing the given equation with y = mx + c
slope (m) = - 8/5
Hope it will help :)
Answer:
-8/5
Explanation:
The equation is written in slope-intercept form, aka y = mx + b, where m is the slope and b is the y-intercept.
In slope intercept, the slope is always the number that comes before x.
In the equation y = -8/5x + 2, that number is -8/5.
Hence, the answer is -8/5.
