You have to get x on its own.
5x=49-4
5x=45
45 divided by 5
Therefore x=9

Okay -

So, the goal when we have an equation is to find the value of the variable. So, let's isolate that variable on <em>one </em>side of the equation!

<em>* original equation </em>
<em>5x + 4 = 49.

</em><em>* subtract four from both sides. if you do something on one side of the equation, you have to do it on the other.
</em><em>5x + 4 - 4 = 49 - 4.

* now we are going to divide 5 on both sides to isolate x.
5x/5 = 45/5.

* and our answer is...
x = 9. =)

Answer:

A) 0.3

Step-by-step explanation:

You need to add all of them together first,

126 + 201 + 107 + 120 + 46 = 600

Out of 600, 201 is e, so 201/600 = 0.335, which is also just 0.3

Answer:

C. 2, -2, -6

Step-by-step explanation:

18, 14, 10, 6, ?

2 - 4 = -2

-2 - 4 = -6

They are subtracting each number by 4 to get the next one that continues.

Hope this helped!

Given:

a^3+3a^2-5a

To Find:

The degree of the polynomial= ?

Solution:

The degree of the polynomial   is the value of the greatest exponent of any expression (except the constant ) in the polynomial. To find the degree all that you have to do is find the largest exponent in the polynomial

Here in the given polynomial

a^3+3a^2- 5a

The terms are

a^3

3a^2

5a

The term  a^3 has  the largest exponent of  3
