Answer:
so the which page that will have the 3 sticker, we must solve the least common multiple of 30, 50, 60. A common multiple is a number that is a multiple of two or more numbers. The common multiples of 3 and 4 are 0, 12, 24, ....
The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.
so the least common multiple of 30, 50 and 60 is 300. so the page that will have 3 stickers is 300th page
Step-by-step explanation:
Answer: x<4
Step-by-step explanation:
−2(x−3) + 4 > 3x − 10
-2x + 6 + 4 > 3x - 10
-2x + 10 > 3x- 10
-5x > -10 - 10
-5x >-20 when divide a negative in an inequality, change the sign.
x< 4
you would multiply 10 x -12 by distributing the 10 into the parenthesis.
The answer would be negative because a postive times a negative is a negative.
The answer is -120
Answer:
30 each of 23% bars and 18 each of 79% bars
Step-by-step explanation:
If x is the number of 1 kg 23% copper bars, and y is the number of 1 kg 79% copper bars, then:
x + y = 48
0.23x + 0.79y = 0.44(48)
Substituting and solving:
0.23x + 0.79(48-x) = 0.44(48)
0.23x + 37.92 - 0.79x = 21.12
16.8 = 0.56x
x = 30
y = 48 - x
y = 18
You need 30 each of 23% bars and 18 each of 79% bars.
