2/5+3/8 5th grade Math. Please help.

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.

Natali [406]

right 3 units down 5 units

$f(x)=x^2$

right 3 units = (3,0)

down 5 units = (0,-5)

vertex = (h,k) therefore.

$g(x)=(x-3)^2-5$

Then convert the vertex form into standard form for the equation in the choice.

$g(x)=(x-3)^2-5\\g(x)=(x^2-6x+9)-5+9\\g(x)=(x^2-6x)+4\\g(x)=x^2-6x+4$

Thus, the answer is B.
