Answer:

it you're asking for like an equation like "4x +3 = 15 " then you do the opposite of what the equation is doing. Basically undoing the problem to get back to the roots of it. like for the example i provided you would subtract 3 from both sides, because it was added originally. then you would divide both sides by 4 because originally you were multiplying.

Plastic cups come in packages of 24 and straws come in packages of 20, whats the smallest number of each that could be bought so
Aleks04 [339]

Answer:

120

Step-by-step explanation:

No. of plastic cups = 24

No. of straws =20

We need to find the smallest number of each that could be bought so that you had the same amount of cups and straws.

Prime factrisation of 24 = 2×3×2×2

Prime factorisation of 20 = 2×5×2

LCM = 120

Hence, the smallest number of each type will be 120.

B is located 3 lines to the left of -1, so it would be located at - 1 3/5.


Am absolute value is a positive number so - 1 3/5 would become 1 3/5.

The answer would be A. 1 3/5
