The system of inequalities that can be used to determine the amounts is given by:

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

A system of inequalities works similarly to a system of equations, just the equality symbol is replaced by an inequality symbol(less, more, different,...).

In this problem, the variables are:

He bought glass vases that cost $22 each and ceramic vases that cost $14 each. The total cost of the vases came to more than $172, hence:

22x + 14y > 172.

Also, Ben bought no more than 10 vases in all, hence:

Step-by-step explanation:

Answer:

8x - 7y = 56

Step-by-step explanation:

in order for lines to be parallel they need to have the same slope, the easiest way to determine if they have the same slope is to change the equations into y = mx + b form by solving for y and seeing where m=8/7

so 8x - 7y = 56

-7y = 56 - 8x

y = 56/-7 -8x/-7

y = -8 + 8/7 x

6.28 feet is the  circumference of a circle with a diameter of 2 feet

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The circumference of a circle is given by the formula:

Circumference=2πr

Where two times of r is equal to diameter

circumference =πd

The diameter is given as 2 feet, so we can substitute this value into the formula:

circumference = 3.14 x 2

Three point one four times of two

We get six point two eight

= 6.28 feet

Therefore, 6.28 feet is the  circumference of a circle with a diameter of 2 feet

Answer:

1) x = 4

2) a square root cannot be equal to a negative value

Step-by-step explanation:

1) add 1 to each side

2) square each side

(√2x + 1)² = 3²

2x + 1 = 9

2x = 8

x = 4

2) subtract 4 from each side

√2x + 1 ≠ -5

Answer:18

Step-by-step explanation:

Note: Mathematicians start counting at 1, so by convention, n=1 is the first term. So we must define what the first term is. Then we have to figure out and include the common difference.

Taking a look at the examples again,

Answer:

None, the sum of those angles does not equal 180 degrees

Answer:

The answer of this question is none. The sum of these three angles is 160°. So, none of the triangles can be constructed with angles measuring 60°, 60° and 40°

Step-by-step explanation:

All sides of the triangle are the same length.

Answer:

60 is the best answer right

Answer:

x=15

Step-by-step explanation:

the angles are supplementary meaning that they will add up to equal 180 so we write the equation

6x+10+4x+20=180 and solve for x

step 1 combine like terms 6x+4x =10x and 10+20=30

10x+30=180

step 2 subtract 30 from each side

10x=150

step 3 divide each side by 10

x=15

Step-by-step explanation:

if the lines are parallel it means they are equal so,

6x+10=4x+20

6x-4x=20-10

2x=10

2x=10

2 2

x=5

6(5)+10 4(5)+20

30+10 20+20
