5 = 1*5

12 = 1*2*2*3

15 = 1*3*5

Least common multiple of 5, 12, 15 is

1*5*2*2*3= 60

I believe it’s 60 as 5, 12 and 15 all go into it and it’s the lowest number they all times to make!

8. A number is of another number. The difference of the numbers is 18. (Assume that you are subtracting the
bezimeni [28]

Answer:

Step-by-step explanation:

"A number is<u> [WHAT?] </u>of another number."  It appears the <u>WHAT??</u> is missing.  If it is a word such as "twice," it can be solved in this fashion.

Let the numbers be X and Y, with Y the larger number.

A number is <u>twice</u> another number:  Y = 2X

The difference of the numbers is 18:  Y - X = 18

Use the first equation (Y = 2X) in the second by replacing "Y" with (2X):

Y - X = 18

2X - X = 18

X = 18

Y = 2X, so Y = 36

22. Which equation has solutions of -2 and 3?
tatyana61 [14]

Answer:

  B. y=x²-x-6

Step-by-step explanation:

Consider the product ...

  0 = (x -a)(x -b) = x² -(a+b)x +ab

This equation has solutions x=a and x=b. You will note that ...

  • the constant is the product of the solutions (ab)
  • the coefficient of x is the opposite of their sum (-(a+b))

For solutions of -2 and 3, the constant will be (-2)(3) = -6. This eliminates choices C and D.

The sum of the solutions is -2+3 = 1, so the coefficient of x is -1, matching choice B.

Sara borrowed $5,000 from her father at a simple interest rate of 12.5% per year. Over a two - year period, she made equal month
Olin [163]

The formula for simple interest is:

A = P(1+rt)

Where P = amount borrowed

r = interest rate

t = time of loan


A = 5000(1 + 0.125*2)

A =6,250

The total amount she paid back was $6,250


For her monthly payment divide total paid back by 24 months ( 2 years = 24 months)


6250 / 24 = 260.42


Her monthly payment was $260.42
