Answer:
x = 330
Step-by-step explanation:
480 + 50 = 530
530 - 200 = 330
330 = x
Answer:
2/(x+7)
Step-by-step explanation:
x²+5x-14 factors as (x-2)(x+7)
SO - multiply the fraction on the right by x+7 (both top and bottom)
Then both have the same denominator (x-2)(x+7), and the 1 becomes x+7.
Then you combine the fractions to make ((3x+3)-(x+7))/(x-2)(x+7).
This becomes (2x-4)/(x-2)(x+7).
You can factor the 2 out of the numerator for 2(x-2).
You now have 2(x-2)/(x-2)(x+7)
The (x-2)’s cancel out and you are left with
2/(x+7)
Answer:
<u>The solution to the system of equations given is (3, 2)</u>
Step-by-step explanation:
Let's solve the system of equations given:
2y = 4
-x = -3
****************
2y = 4
y = 4/2
y = 2
____________________
-x = - 3
x = 3
<u>The solution to the system of equations given is (3, 2)</u>
It is zero *more characters to fulfill answer requirements*
In general, the statement 'a is subtracted from b' is written as
![b-a](https://tex.z-dn.net/?f=b-a)
Therefore, 'A number is subtracted from 2' is written as,
![2-x](https://tex.z-dn.net/?f=2-x)
The answer is 2-x
