x + y = 36       ....(1)

And,

xy = 315         .....(2)

We know that,

⇒  

⇒  

⇒  

x - y = 6       ....(3)

Adding (1) and (3), we get

x + x = 36 + 6 ⇒ 2x = 42

⇒ x = 21

Putting the value of x in (1), we get

21 + y = 36

⇒ y = 36 -21 = 15

Hence, the numbers are 21 and 15.

Divided 80 by my number, and then added 13. The result was 93. What was my number?
igor_vitrenko [27]

The number is 6400.

We have given that,

divided 80 by my number, and then added 13.

<h3>What is the expression?</h3>

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Suppose the number is x

\frac{x}{80}+13=93

Subtract  13  from both sides

\frac{x}{80}+13-13=93-13

\frac{x}{80}=80

Multiply both sides by 80

\\\frac{80x}{80}=80\cdot \:80

x=6400

Therefore the number is 6400.

20 POINTS WILL MARK AS BRAINLIEST AND SAY THANKS In 2000, the cost of many items increased because the increase in the cost of g
antoniya [11.8K]
Let the cost of gasoline in the year 2000 be represented b the equation
y = a + b*x
where
x = months, counted from January
y = cost, dollars

The given data in the table is
Month:        Jan  Feb  Mar  Apr  May  Jun  Jul  Aug  Sep  Oct  Nov  Dec
x, months:       1       2     3       4      5       6     7      8      9     10     11      12
y, dollars:     ---      ---     ---     ---   1.76   2.13   ---     ---    ---      ---    ---     ---

When x = 5, y = 1.76.
Therefore
a + 5b = 1.76               (1)

When x = 6, y = 2.13
Therefore
a + 6b = 2.13              (2)

Subtract equation (1) from (2).
a + 6b - (a + 5b) = 2.13 - 1.76
b = 0.37

From (1), obtain
a = 1.76 - 5b
   = 1.76 - 5*0.37
   = -0.09

The required equation is
y = 0.37x - 0.09
The graph shows the line, with the given data for May and June.

Answer: D.  y = 0.37x - 0.09
