reminder on addition / subtraction

+ (- ) = - or - ( + ) = -

- ( - ) = +

(+) + ( +) = +

7 + (- 5) = 7 - 5 = 2 ← not negative

1 + (- 1) = 1 - 1 = 0 ← not negative

- 3 + 4 = 1 ← not negative

(- 3) + 2 = - 1 ← negative

The correct answer is: D. (-3) + 2 = -1

The other ones result in a positive sum:

A: 7 + (-5) = 2
B: 1 + (-1) = 0
C: (-3) + 4 = 1

a store had a sale on art supplies. the price p of each item was marked down 60%. which expression represents the new price

If the price of the item drops by 60% then that means the new price is 40% of the original

new price = p*0.4

ex:
new price = $100*0.4= $40
new price= $75*0.4 = $30

Find the least common multiple of: 12x^3y^2 and 15x^2y^5

allochka39001 [22]

Answer: $60x^3y^5$

Step-by-step explanation:

Least Common Multiple :The least positive number that is a multiple of two or more numbers.

To find : The least common multiple of: $12x^3y^2$ and $15x^2y^5.$

Since, $12x^3y^2=2\times2\times3\times x^3y^2$

$15x^2y^5=3\times5\times x^2y^5$

The least common multiple of: $12x^3y^2$ and $15x^2y^5.$ = $2\times2\times3\times5\times x^3y^5=60x^3y^5$ [take highest power of x and y ]

Hence, the least common multiple of: $12x^3y^2$ and $15x^2y^5.$ = $60x^3y^5$
