Given:
The equation is
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{4}{10}=\dfrac{2}{5}[/tex]
To find:
Whether the given equation is true or not.
Solution:
In addition of two fractions, we can not add numerator and denominator separately. First we need a common denominator, then we add numerators.
We have,
[tex]\dfrac{1}{2}+\dfrac{3}{8}[/tex]
Taking LCM, we get
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{1\times 4+3}{8}[/tex]
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{4+3}{8}[/tex]
[tex]\dfrac{1}{2}+\dfrac{3}{8}=\dfrac{7}{8}\neq \dfrac{4}{10}[/tex]
So, the given equation is not true.
Therefore, the correct option is B.

3/5x+2=5.6 what is x?
Answer:
x= 1/6
Step-by-step explanation:
Multiply all the numbers by x and cancel:
3/5 + 2x =5.6x
2x + 3/5 = 5.6x (Simplify both sides of the equation)
2x + 3/5 - 5.6x = 5.6x - 5.6x (Subtract 5.6x from both sides)
-3.6x + 3/5 = 0
-3.6x + 3/5 - 3/5 = 0 - 3/5 (Subtract 3/5 from both sides)
-3.6 = -3/5
-3.6x/-3.6 = -3/5 / -3.6 (Divide both sides by -3.6)
x = 1/6

The sale price of every item in a store is 85% of its usual price. Find the price of the following items given their usual price. The usual price of a soccer ball is $19.80, what
is its sale price?
Answer:
$16.83
Step-by-step explanation:
If the usual price is $19.80 and they are on sale for 85% of the usual price, you can set this up in the form of a proportion.
[tex]\frac{85}{100} = \frac{x}{19.80}[/tex]
With this, you first multiply 85*19.80 and then you divide that answer by 100 to solve for x, the sale price.
Another way you can approach it is by changing 85% into it's decimal form (.85) and multiplying this by the original price (19.80).
How do I solve this problem and what is the answer? I would really appreciate it if you could help me please! :)

method for solving 5(x-2) -2(x-5)=9 is shown below. Identify the property used to obtain each of the two indicated steps.
Answer:
1) (5x-10)(-2x+-10)=9
2)(3x-0)=9
Step-by-step explanation:
The property used for the expression (5x-10)(-2x+-10)=9 is distributive.
This property states that multiplying the sum of two or more addends by a number produces the same result as multiplying each addend separately by the number and then adding the products together.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the step is 5(x-2) -2(x-5)=9. The step will be solved by the distributive property. By multiplying the two parts with each other and simplifying them.
