Answer:
13/30
Step-by-step explanation:
Add: -1/
3
+ 2/
5
= -1 · 5/
3 · 5
+ 2 · 3/
5 · 3
= -5/
15
+ 6/
15
= -5 + 6/
15
= 1/
15
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(3, 5) = 15. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 5 = 15. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - minus one third plus two fifths = one fifteenth.
Subtract: 1/
2
- the result of step No. 1 = 1/
2
- 1/
15
= 1 · 15/
2 · 15
- 1 · 2/
15 · 2
= 15/
30
- 2/
30
= 15 - 2/
30
= 13/
30
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 15) = 30. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 15 = 30. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - one half minus one fifteenth = thirteen thirtieths.
Answer:
so what you do is you divide 30 by 4.5 then when you get the density you divide that by the 10 pennies so you get the density of 1 penny
Step-by-step explanation:
(3³ x 5³)² - 2
( 27 x 125)² - 2
125 x 27 = 3375
3375² = 11,390,625
11,390,625 - 2 = 11,390,623
The 45th term of the arithmetic sequence is 178. Option C
<h3>How to determine the term</h3>
Given the arithmetic sequence formula as;
an = 2 + 4(n − 1)
we have n = 45
Let's substitute the value of 'n' into the formula;
a = 2 + 4( 45 - 1)
expand the bracket
a = 2 + 4(44)
a = 2 + 176
a = 178
The 45th term is 178
Thus, the 45th term of the arithmetic sequence is 178. Option C

y= mx/z
You isolate the variable by dividing each side by factors that don't contain the variable, which gives you the answer as "mx" as the numerator and "Z" as the denominator.
