Answer:
564 pencils
Step-by-step explanation:
1 box = 12 pencils
25 boxes = 25 × 12 pencils = 300 pencils
22 boxes = 22 × 12 pencils = 264 pencils
300 + 264 = 564 pencils
Answer:
below
Step-by-step explanation:
5x - 3y > 30
-3y > -5x + 30 divide by negative switches the inequality
y < 5/3x - 10 y is less than 5/3x - 10 so shade below the line
Answer:
C. 609
Step-by-step explanation:
In the question, 4-digits number were given to be divided by a 2-digits number. Without performing the division, it is only reasonable to say that the quotient will be a 3-digits number.
In the given options, the only 3-digits number is 609
Also, you can multiply 609 by 12 to check how reasonable your guess is.
⇒ 609 x 12 = 7308
The difference between 7315 and 7308 is 7.
The remaining number (7) is not up to 12 and when 7 is divided by 12 it will not give a whole number digit.
Therefore, the only reasonable quotient in the given options is 609.
One way to find the least common multiple of two numbers is to first list the prime factors of each number.
8 = 2 x 2 x 2
Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
2: three occurrences
3: one occurrence
So, our LCM should be
2 x 2 x 2 x 3 = 24.
So, Marco can buy, at the very least, 24 beads of each color to have equal colors of beads.
