Answer: A rational expression is a ratio of two polynomials.
Step-by-step explanation: To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same. In other words, we must find a common denominator.
Adrian are 3 ani, iar tatăl lui are 34 de ani. Peste câți ani Adrian va fi de două ori mai tânăr decât tatăl său?
Answer:
27 years
Step-by-step explanation:
Given that :
Adrian's age = 3
Father's age = 34
In how many years will Adrian be twice as young as his father?
Let the number of years = x
2(3 + x) = 34 + x
6 + 2x = 34 + x
2x - x = 34 - 6
x = 28
ANSWER THIS PLEASE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
y=-2/3×
Step-by-step explanation:
y-(-4)=-2/3(×-6)
y+4=-2/3x+4
then subtract 4
y=-2/3×
you use the point slope form
y-y1=m(x-x1)
m equals slope

5. A college student would like to purchase a ticket to the Olympics 100-meter men's race.
The average cost is $1,200 (this is real life). The student has already saved $500 from
their fast food job. They get paid $12 an hour.
a.
Write an inequality that shows how many hours the student will need to work to earn
more than $1,200.
Answer:
12h greater than or equal to 1200
Step-by-step explanation:
Let h = the number of hours worked. Since they make $12 per hour, then 12h represents how much they make. They need $1200 for the event, so they need to make AT LEAST that amount. That means 12h must be greater than or equal to $1200.

Consider the equation 2(ax+3)=4x−3(4x+8). For what value of a is there no solution to the equation?
Answer:
the value of [tex]a[/tex] such that there is no solution to the equation is [tex]a = -4[/tex].
Step-by-step explanation:
Let first simplify the expression presented on statement. The equation has no solution if and only if [tex]a[/tex] is eliminated in the process and an absurd is the result (i.e. [tex]0 = 7[/tex]).
[tex]2\cdot (a\cdot x + 3) = 4\cdot x -3\cdot (4\cdot x + 8)[/tex]
[tex]2\cdot a\cdot x +6 = 4\cdot x -12\cdot x -24[/tex]
[tex]2\cdot a \cdot x+6=-8\cdot x-24[/tex]
[tex]2\cdot a\cdot x +8\cdot x = -30[/tex]
[tex]2\cdot (a+4)\cdot x = -30[/tex]
[tex](a+4)\cdot x = -15[/tex]
To obtain an absurd, we need that [tex]a+4 = 0[/tex]. Hence, the value of [tex]a[/tex] such that there is no solution to the equation is:
[tex]a = -4[/tex]
Let prove the certainty of the result. We find that an absurd exist: ([tex]a = -4[/tex])
[tex]0 = -15[/tex]
Considering the equation
[tex]\rm 2(ax+3) = 4x - 3(4x+8) \\[/tex]
The equation given above has no solution when a = -4
On simplifying the given equation we can find that
[tex]\rm 2(ax + 3) = 4x-3(4x+8)\\2ax + 6 = 4x- 12x-24 \\2ax +6 +24 = -8x \\2ax +30 = -8x \\2ax+8x +30 = 0[/tex]
The equation has no solution when the equality of both sides does not hold true .
Hence by observation we can say that the equation has no solution when
[tex]\rm 2ax = -8x \\\\2a =-8\\\bold{a =-4} \\[/tex]
So the equation given above has no solution when a = -4.

9. Zay's age is twice his sister Taylor's age. If they add their ages together,
they get 27. How old are Zay and Taylor?*
A. Zay is 12; Taylor is 15
B. Zay is 18; Taylor is 9
C. Zay is 16; Taylor is 8
D. Zay is 9; Taylor is 18
Answer:
d
Step-by-step explanation:i use my brain ;)
Answer: B
Step-by-step explanation: it says that their combined age is 27 so that is what the equation must equal. It says that Zay is twice Taylor's age so lets say Taylor's age is X, Zay's age would be 2X. Combined it would be 3x. So the equation is
27= 3X
Now if you divide by 3 in both sides you should get 9. Now that's Taylor's age. Multiply by 2 and you get 18 AKA Zay's age.
