Answer:
The number line is shown below.
Step-by-step explanation:
We need to represent number that is less than 3 on a number line.
Let x be numbers.
So,
.
Now, we have a number which represents x<3. Here 3 is not included in the solution set, so there is an open circle on 3 and left side of 3 are in the solution set.
The number line is shown below.
Answer:
Therefore the solutions are

Step-by-step explanation:
Given:
.........( 1 )
................( 2 )
To Find:
x = ?
y = ?
Solution:
Substituting ' y ' in Equation 1 we get

Using identity (A+B)²=A²+2AB+B² we get

Now Substitute x =0 in equation 2 we get

Or
Now Substitute x =-4 in equation 2 we get

Therefore the solutions are

Answer:

Step-by-step explanation:
For calculating the sales tax of a product, it is required to first multiply the original cost price of the product by the sales tax percentage.
Once the sales tax has been computed add it to the original cost price in order to determine the total cost of the product.
The formula of final amount is:

Here,
A = final amount
P = original cost price
S = sales tax percentage
Answer:
x = 47
Step-by-step explanation:
Every triangle's interior angles add up to 180°.
Let's make an equation.
x + 102 + 31 = 180
x + 133 = 180
x = 47
The answer is 6(N+12)
This is because it is telling you that the equation is six times a SUM of a number and twelve. So the number and 12 added together are multiplied by 6.
