The next step to solve the equation si 2x = 12.
Option B is correct.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
5x − 3x + 4 = −4 + 20
Now, simplifying the equation
5x - 3x +4 = 16
2x + 4= 16
Now, the next step is
2x = 12

6 1/6- 5 3/4=x
1) convert the fractions to a common multiple like 12, but what the denominator is multiplied by so is the numerator
6 2/12- 5 9/12
2) subtract the 6 and 5 than subtract numerators
5/12 is the answer
The values of the two numbers are 14 and 22 respectively.
Let the numbers be represented by x and y
Based on the information given, the equation to represent the information will be:
x + y = 36 ..... i
2x - y = 6....... ii
Add equation i and ii together
3x = 42
x = 42/3
x = 14
Since x + y = 36
Then, we'll put the value of x into the equation and this will be:
x + y = 36
14 + y = 36
y = 36 - 14
y = 22
Therefore, the values of x and y are 14 and 22 respectively.

Answer:
C
Step-by-step explanation:
the answer would be C, or y = 0.125x + 625 because in the problem, it says that the store would require an upfront payment of $25 PLUS $50 a month, then 12.5% interest at the end of the year, then it asks what the equation would be after 12 months. SO we know that is a year (since there are 12 months in a year) so we would multiply that by number by the $50 we would have to pay a month which would look like this: 12 months x $50 a month = $600. then, we would add the initial $25 dollars, which would give us a total of $625 which we'd add to the equation. next, if we look at 12.5% and then at our answer choices, we can see that they converted the percent to a decimal. 12.5% is equivalent to 0.125, therefore our final answer is C!

140% of what number is 56
The value of the unknown number is 40.
Given the parameter:
"140% of what number is 56"
Let's represent the unknown number as "x."
To find the number that represents 140% of a certain value, simply set up an equation.
140% of the number = 56
140% of x = 56
140% × x = 56
First, convert the percent to decimal:
140% = 140/100 = 1.4
Now, we have:
1.4 × x = 56
Solve for x.
Divide both sides of the equation by 1.4:
x = 56/1.4
x = 40
Therefore, the value of x is 40.
