Answer:

31/40

Step-by-step explanation:

Given expression:

\dfrac{2}{5} + \dfrac{3}{8}

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.

\rightarrow \dfrac{2 \times 8}{5 \times 8} + \dfrac{3 \times 5}{8 \times 5}

\rightarrow \dfrac{16}{40} + \dfrac{15}{40}

Finally, simplify the expression to determine the solution.

\rightarrow \dfrac{31}{40}

Since 31 is a prime number, we can't simplify this fraction. Thus, the final answer is 31/40.

finding the distance from (–6, 2) to the origin. Use (0, 0) as (x1, y1). d = StartRoot (x 2 minus x 1) squared + (y 2 minus y 1)
Naddik [55]

Answer:

2√10

Step-by-step explanation:

Given the coordinates (-6, 2) and (0,0)

We are to find the distance between the coordinates. Using the distance formula;

d = √(x2-x1)²+(y2-y1)²

d = √(0-2)²+(0+6)²

d = √(-2)²+(6)²

d = √4+36

d = √40

d = √4*10

d = 2√10

Hence the required distance is 2√10

What is the solution to the system of equations graphed below
Morgarella [4.7K]
Equation 1 ==> y = -4x + 2
Equation 2 ==> y = x - 3

Substitude equation 2 into 1

x - 3 = -4x + 2
-5 = -5x
x = 1

Substitude x into equation 2

y = 1 - 3
y = -2

Coordinates is (1, -2)
Answer is D.
