Given:
Markers are sold in packages of 12 and pens are sold in packages of 8.
To find:
Least amount of markers and pens Rick needs to buy to have an equal number of markers and pens
Solution:
To find the least amount of markers and pens, we need to find the LCM of 12 and 8.
Prime factors of 8 and 12 are


To find the LCM, multiply all factors but the common factors are included only once.


Therefore, the least amount of markers and pens Rick needs to buy to have an equal number of markers and pens is 24.
Margot could pickle 500 cucumbers in 2 hours.
She got tired and reduced her rate by one half.
=> 250 cucumber in 2 hours
Let's solve how long would it take her to pickle 2000 cucumbers at thenew rate.
=> 2000 / 250 = 8 times 2 hours
=> it will take her 16 hours to do so.
Answer: x ≥ -1
<u>Step-by-step explanation:</u>
4(2x - 3) ≥ 4(x - 4)
8x - 12 ≥ 4x - 16 <em>distributed 4 into 2x - 3</em>
4x - 12 ≥ -16 <em>subtracted 4x from both sides</em>
4x ≥ -4 <em>added 12 to both sides</em>
x ≥ -1 <em>divided both sides by 4</em>
