I think b not for sure
but i hope this helps
The Least Common Multiple (LCM) will calculate when they are watered on the same day.
LCM of 4 and 7 is 28.
Answer: They will be watered together every 28 days.
Answer:
(a). 300r + 425p ≤ 6,600
(b). No, it’s not considered overweight
Step-by-step explanation:
In this question, we are to write an equation that shows the number of refrigerators and pianos the truck could carry.
Let the number of refrigerators be r and the number of pianos be p
By using their individual weights, the equation is as follows;
300r + 425p ≤ 6,600
To the second question, we want to consider if 10 refrigerators and 8 pianos are overload.
To get this, we simply multiply the number of each by their individual weights;
That would be;
300(10) + 425(8) = 3000 + 3,400 = 6,400 lbs
This is not considered overweight as it is less than 6,600 lbs
x -2y = 2
3x +y = 6 multiplie both sides by 2 => 6x +2y = 12
x -2y = 2
6x +2y = 12
------------------- assum the same terms
7x 0 = 14
x = 14/7
x = 2
