Answer:
Move all terms containing x to the left side of the equation.
−5x+5=25
Move all terms not containing x to the right side of the equation.
−5x=20
Divide each term by −5 and simplify.
x=−4
Step-by-step explanation:
Answer:
79/25
Work:
Firstly, you have to change the decimal portion of 3.16 (0.16) into a fraction, then you simplify it by a common factor, which is 4. You then convert your whole number, which is 3, into an improper fraction by multiplying it by 25 and making that the numerator, 25 being the denominator of the fraction. Then, you add the two fractions and voila! You have a simplified fraction!
0.16 = 16/100
16/100 = 4/25
3 x 25 = 75
75/25 + 4/25 = 79/25
Answer: The system of equation is,
2 ( x + y ) = 50
x = 2 y - 5
Step-by-step explanation:
Let x represents the length of the rectangular brownie and y represents the width of the rectangular brownie.
Thus, the perimeter of the brownie = 2 ( x + y )
But, According to the question,
Perimeter of the brownie = 50,
2 ( x + y ) = 50
The length of the brownie is 5 less than twice the width,
That is, x = 2 y - 5
Thus, the required system of equation is,
2 ( x + y ) = 50 , x = 2 y - 5
Hello!
We have the following data:
a1 (first term or first year salary) = 32000
r (ratio or annual increase) = 300
n (number of terms or each year worked)
We apply the data in the Formula of the General Term of an Arithmetic Progression, to find in sequence the salary increases until it exceeds 34700, let us see:
formula:
* second year salary




* third year salary




* fourth year salary




* fifth year salary




We note that after the first five years, Mr. Browns' salary has not yet surpassed 34700, let's see when he will exceed the value:
* sixth year salary




* seventh year salary




* eighth year salary




* ninth year salary




* tenth year salary




we note that in the tenth year of salary the value equals but has not yet exceeded the stipulated value, only in the eleventh year will such value be surpassed, let us see:
* eleventh year salary




Respuesta:
In the eleventh year of salary he will earn more than 34700, in the case, this value will be 35000
