Eight friends ate at a restaurant and agreed to share the bill equally. Because Judi forgot her money, each of her seven friends

paid an extra $2.50 to cover her portion of the total bill. What was the total bill?

Judi's share was (7 x $2.50) = $17.50 .

That was really one share out of eight.
So the total bill was

(8 x $17.50) = $140.00 .

1) let both have x ,
so putting in eqn ;

4x+0.50 = 9x-3
5x=2.50
x=0.50

therefore both have 50 p in the beginning !!

2) let the number be x

so in eqn;

(x+18)/2=5x
x+18=10x
9x=18
x=2

so the number must be 2 !!

if you have still any problem, comment !!

A, B and C are corners of a parallelogram

slamgirl [31]

Answer:

Step-by-step explanation:

in a parallelogram diagonals bisect each other.

so mid points are same.

Let coordinates of D be (x,y)

mid point of AC=midpoint Of BD

(-2+5)/2=(x+3)/2

x+3=-3

x=-3-3=-6

x=-6

(3-3)/2=(2+y)/2

y+2=0

y=-2

so D is (-6,-2)

Find the equation of the line using exact numbers

Katen [24]

Answer:

y = - $\frac{1}{3}$ x + 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = $\frac{y_{2-y_{1} } }{x_{2-x_{1} } }$

with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (3, 4) ← 2 points on the line

m = $\frac{4-5}{3-0}$ = $\frac{-1}{3}$ = - $\frac{1}{3}$

the line crosses the y- axis at (0, 5 ) ⇒ c = 5

y = - $\frac{1}{3}$ x + 5 ← equation of line
