The answer is 96
24 pieces of wood all cut in half so multiply by 2
24x2=48
Now cut 48 pieces in half so multiply by 2
48x2=96
Answer:
Find the LCD of the first two, then the LCD of that and the third one.
Step-by-step explanation:
You can do it by finding the LCD of two of the denominators, then the LCD of that and the third denominator.
Or, you can factor each of the denominators and find their LCM by multiplying the unique factors to their highest powers.
___
<u>Example:</u>
1/21 + 1/35 + 1/45
The LCD of 1/21 and 1/35 is (21·35)/5 = 105. The LCD of 1/105 and 1/45 is ...
(105·45)/15 = 315
__
Using factoring ...
- 21 = 3·7
- 35 = 5·7
- 45 = 3²·5
LCD = 3²·5·7 = 315
Answer:
C) Rational Numbers
Step-by-step explanation:
Integers include all whole numbers both negative and positive. This is basically just any number without a decimal, and since 3.5 has a decimal, it can't be an integer.
Natural numbers also don't include numbers without decimals. They only include whole numbers that a positive.
Irrational numbers have a repeating decimal that cannot be represented as a fraction. However, we know that 0.5 can be represented as 1/2
A rational number is a number that can be in the form p/q
, where p and q are integers and q is not equal to zero. We can change 3.5 to be in the form p/q by changing it to be an equivalent improper fraction of 7/2
Answer:
9x +135
Step-by-step explanation:
9(x + 8) +63 (by PEDMAS distribute 9 into parentheses first)
= x(9) + 8(9) +63
= 9x + 72 + 63
= 9x +135 [ =9(x+15) ]
