What is the solution to the equation 4x + 2(x - 3) = 3x + x - 12? / A -3/B -1/C 1/D 3

1 answer:

3 0

Remember you can do anything to an equation as long asyou do it to both sides

4x+2(x-3)=3x+x-12
distribute and expand
4x+2x-6=4x-12
6x-6=4x-12
minus 4x both sides
2x-6=-12
add 6 both sides
2x=-6
divide by 2
x=-3

What percent of 50 is 18

Rom4ik [11]

Answer:
36%

Explanation:
To get the percentage of a fraction, we follow these steps:
1- simplify the fraction (get its simplest form)
2- multiply this simplest form by 100%

For the given, we have:
1- the fraction is $\frac{18}{50}$
We can note that both the numerator and denominator are divisible by 2. Therefore, we can reduce the fraction into $\frac{9}{25}$

2- Since no further simplification can be applied, therefore, our simplest form is $\frac{9}{25}$

3- we multiply this simplest form by 100%:
$\frac{9}{25}$ * 100 = 36%

Based on the above:
18 is 36% of 50

Hope this helps :)
