7 3/10 + 6 1/3 + 2 7/10
First change them to improper fractions
73/10 + 19/3 + 27/10
now find the common denominator which would be 30
73/10 = 219 /30
19/3 = 190/30
27/10 = 81 /30
now add (219 + 190 + 81) = 490/30
now divide 490 ÷ 30 = 16 1/3
Your answer is 16 1/3
Hope this helps. :)
Answer:
60
Step-by-step explanation:
We have to find least common denominator for these fractions or we just have to find the least common multiple for 15, 6 and 4
In order to find the least common multiple, we have to represent these numbers as factors of prime numbers:
15 = 3 * 5
6 = 2 * 3
4 = 2 * 2
Least common multiples will be common factors (considering that there are no more than of them in other numbers) and the uncommon factors. Then, we can write that:
2 * 2 * 3 * 5 = 60 (there are two 2's, one common 3 and an uncommon 5)
The denominator will be 60 for the least common multiples.
Answer:
The coefficient is -5, and the base is 12.
Step-by-step explanation:
The coefficient is the number that the variable is being multiplied by in an expression, so -5 would be the coefficient in the expression 
. The base would be the little subscript number that is next to the variable, so the base in the expression is 12.
Answer:
The value of sin X = 12 / 13
Step-by-step explanation:
Given
- The side opposite to angle ∠X = 12
To determine
sin X = ?
We know that the trigonometric ratio involving sin Ф such as
sin Ф = opposite / hypotenuse
Here:
- The side opposite of Angle X = 12
so substituting Ф = X, opposite = 12 and hypotenuse = 13 in the equation
sin Ф = opposite / hypotenuse
sin X = 12 / 13
Therefore, the value of sin X = 12 / 13
Answer:
x = 12
