An electronics store had a special sale on two different models of calculators. The more high-tech model sold for $33.02 and
the older model sold for $18.55. All together, 28 calculators were sold. Total sales came out to $736.45. Which system of
equations can be used to determine how many high-tech models were sold, x, and how many older models were sold, y?

Answers

Answer 1

Answer:

$736.45/$33.02 = 22.30 high tech

x($33.02) = $736.45

$736.45/$18.55 = 39.70 older models

y($18.55) = $736.45

If the perimeter of a square is 7 feet how many inches long is the square on each side?

Answers

Answer:

7÷4=1.75

Step-by-step explanation:

..............

The length of each side of the square is 1.75 feet.

What is square?

"It is a quadrilateral with all sides are equal and all angles are 90°"

What is the perimeter of square?

"The perimeter of square is, P = 4 × a,

where 'a' is the side length of the square."

For given example,

the perimeter of a square is 7 feet.

⇒ P = 7 feet

Let 'a' be the length of each side of the square.

Using the formula of perimeter of a square,

⇒ P = 4 × a

⇒ 7 = 4 × a

⇒ a = 7 ÷ 4

a = 1.75 feet

Therefore, the length of each side of the square is 1.75 feet.

46+30=76
angles in a triangle add to 180°
180-76=104
180-104=76
x=76
To get the answer you add 46 degrees and 30 degrees to get 76 and then all the angles in the inside have to add up too 180 so you substract 76 too 180 and that would give you 104 but you gave to substract it again to get x and that would get you 76

When you using an Inner Join, rows from table that match a common value are the only ones returned.

In SQL server, of we can create a new table by combining rows that have values that match in two or more tables by using an inner join clause.

Logically, this is used to retrieve data from tables that have a common field or appears to have data in both tables.

3(x-2)=18 can somebody plzz help me

Answers

Answer:

x=8

Step-by-step explanation:

3(x-2)=18

3x-6=18

3x=18+6

3x=24

x=24/3

x=8

Given : Simplify 3(x - 2) = 18

Solution : According to the question, here we are given an equation i.e 3(x - 2) = 18 where we need to get the value of x by simplifying it.

3(x - 2) = 18

Cross multiplying 3 to the other side

x - 2 = 18/3

x - 2 = 6

Transposing -2 to the right hand side of the equation to get +2

x = 6 + 2

Adding them we get the final answer

x = 8

Henceforth, the required answer is 8
