Donc pour trouver la réduction de 30% nous allons trouver 30% de 49 alors nous allons faire 30 × 100 × 49 = 14,7 14,7 est la réduction maintenant nous devons faire 49 € -14,7 € soit 34,3 €, le prix est maintenant de 34,3 €, désolé d'utiliser Google Translate pour vous aider, mais j'espère que c'est correct :)
Answer:
Step-by-step explanation: Divison because you would have to do the opposite since u don’t know what x is.
Answer:
y= -5/4x +4
Step-by-step explanation:
To express y in terms of x, we need the equation to be y=....
To do this, we must solve for/isolate the variable, y
5x+4y=16
Subtract 5x from both sides
4y= -5x +16
Divide both sides by 4
y= -5/4x +4
A rational number includes fractions (3/4), integers (-2,-1,0,1,2), and whole numbers (0,1,2,3,4,5).
To convert a fraction into a decimal, you divide the numerator by the denominator. In your case, 4/33 as a decimal is 0.1212121212...etc..
2|x-2|-12=0
Rearrange variables to the left side of the question
2|x-2|=12
Dividing both sides of the equation by the coefficent of variables
|x-2|=12/2
Reduce the fraction
|x-2|=6
Split into two variables
x-2=6 or x-2=-6
Rearrange variables to the left side of the equation
x=6+2
x=8 or x=-4
when x=8
LHS=2|8-2|-12=0
RHS=0
LHS=RHS
x=8 is valid
A variable in mathematics is an alphabet or phrase that stands in for an unknowable amount, unknowable value, or unknowable number. Particularly in the case of algebraic expressions or algebra, the variables are utilised. As an illustration, the linear equation x+9=4 has the variables x and 9 as constants.
A variable is a letter or symbol that stands in for any individual integer in a group of two or more. A constant is a letter or symbol that stands for a single particular number, whether it is known or unknown.
In mathematics, variables serve as stand-ins for unknowable numbers. Variables can be utilized in formulae, equations, and expressions in mathematics. When it's necessary to find the optimum solution, variables are frequently employed.
