Answer:
21
Step-by-step explanation:
The least common multiple is the smallest multiple of the given numbers that is a common multiple for all the numbers being compared.
We have to divide the numbers by numbers that are divisible
15,12
Divide both by 3 -15/3 =5. 12/3 =4
5 and 4 aren’t divisible by any common numbers, we take them as it is
L.C.M = 3*4*5 = 60
Answer is 60
Answer:
3
Step-by-step explanation:
2 1/2 / 5/6
= 5/2 / 5/6
= 5/2 * 6/5
= 6/2
= 3
Hope this helps!
Answer:
Step-by-step explanation:
Part A
2x-3y =21 in slope-intercept form is y=2/3x-7 one you graph the equation it would be a parallel to the equation shown above so there are no intersections
PART B
y=1/3x^2 and y= 2/3x - 5
1/3x^2 = 2/3x-5
1/3x^2=2/3x-5
then u multiply everything by 3
1/3x^2*3 =2/3x *3-5*3
the three for 1/3*3 cancels out so you are left with
1x^2= 2x -15
1x^2-2x+15=0
You can not factor it and well i guess there is no intersection
im sorry if i got this wrong bc i had a similar question just different numbers and i tried to solve this one the way i sloved mine so im not sure of my answer for part b
