Answer:

E. 3x + 6 = 2x + 9

Step-by-step explanation:

The total number of charms that Lydia has in term of x

6 + 3x

The total number of charms that Claudia has in term of x

9 + 2x

Since they have the same number of charms, we can set these 2 equations above equals to each other

6 + 3x = 9 + 2x

x = 9-6 = 3

So E is the correct answer

60 more students voted for Kevin

Step-by-step explanation:

Given

total students = 300

Voted for Jennifer = 40%

Voted for Kevin = 60%

We will find number of students for one of them and then will subtract from total to find the others.

So,

Students who voted for Jennifer:

= 40\%\ of\ 300\\=0.40*300\\=120\ students

Students who voted for Kevin

==Total\ students-Students\ who\ voted\ for\ Jennifer\\=300-120\\=180\ students

In order to calculate that how many more students voted for Kevin :

180-120 = 60

Hence,

60 more students voted for Kevin

2x+3(2)=4<br> This is substitution. Please help I am stuck
Ber [7]

Answer:

x = -1

Step-by-step explanation:

2x + 3(2) = 4      

2x + 6 = 4           Multiply 2 and 3 to get 6.

2x = -2                Subtract 6 from both sides to isolate 2x.

x = -1                   Divide both sides by 2 to find x.

z=a+bi\\\\|z|=\sqrt{a^2+b^2}\\\\z_1=-2,\ z_2=2+2i\\\\\text{the distance between}\ z_1\ \text{and}\ z_2:\\\\|z_2-z_1|=|-2+2i-2|=|-4+2i|=\sqrt{(-4)^2+2^2}\\\\=\sqrt{16+4}=\sqrt{20}=\sqrt{4\cdot5}=\sqrt4\cdot\sqrt5=\boxed{2\sqrt5}

Y^2+5y  the greatest common factor is y so

y(y+5)

...

4x^2-49  this is a "difference of perfect squares" which always factors to:

(a^2-b^2)=(a-b)(a+b), in this case:

(2x-7)(2x+7)

...

5s^2-20  GCF is 5

5(s^2-4)  now the parenthetic term is a difference of squares so

5(s-2)(s+2)
