Answer:
31/40
Step-by-step explanation:
Given expression:
Note: Both fractions must have same denominators if we want to perform addition, subtraction, multiplication, or division.
The only way to simplify this expression is to have a common denominator, which can be determined by the LCM of 5 and 8.
- ⇒ Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45...
- ⇒ Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72...
Multiply the denominators with such a number that is equivalent to 40.
Note: The number you are multiplying should also be multiplied to the numerator.
Finally, simplify the expression to determine the solution.
Since 31 is a prime number, we can't simplify this fraction. Thus, the final answer is 31/40.
Answer:
x = 4
Step-by-step explanation:
Simplifying
3x + 15 = 6x + 3
Reorder the terms:
15 + 3x = 6x + 3
Reorder the terms:
15 + 3x = 3 + 6x
Solving
15 + 3x = 3 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
15 + 3x + -6x = 3 + 6x + -6x
Combine like terms: 3x + -6x = -3x
15 + -3x = 3 + 6x + -6x
Combine like terms: 6x + -6x = 0
15 + -3x = 3 + 0
15 + -3x = 3
Add '-15' to each side of the equation.
15 + -15 + -3x = 3 + -15
Combine like terms: 15 + -15 = 0
0 + -3x = 3 + -15
-3x = 3 + -15
Combine like terms: 3 + -15 = -12
-3x = -12
Divide each side by '-3'.
x = 4
Simplifying
x = 4
Answer:
First Blank: 4*2 = <em><u>8</u></em>
Second Blank: 6*2 = <em><u>12</u></em>
Step-by-step explanation:
The common ratio for the right row is the number thats given on the opposite side of it's left row times 2
Hope this helps!
69% can be written as
69/100
That cannot be reduced any further since 69 and 100 do not have any common factors other than 1
