Madison and Tanisha went out to lunch. The bill came to $18.94. Madison knows that her lunch cost 9.72. How much did Tanisha's l

Finger [1]

Answer:

Tanisha's lunch cost $9.22.

Step-by-step explanation:

Given that,

Total bill = $18.94

Cost for Madison cost = $9.72

Total cost = Tanisha's lunch + Madison's lunch

18.94 = Tanisha's lunch + 9.72

Tanisha's lunch = 18.94 - 9.72

Tanisha's lunch = 9.22

So, Tanisha's lunch cost $9.22.

Can someone help please ?

Average rate of change is defined by (y^-y)/(t^-t) where the ^ means the final(so final y and final t)
So you'd do (8.75-2.75)/(12-4) which is 6/8 which is 3/4 of a dollar per week

What is the point-slope form

Katen [24]

Answer:

$y-8=-\frac{2}{3}(x+3)$

Step-by-step explanation:

The point-slope from is: $y-y_{1}=m(x-x_{1})$

When:

M is the slope

x1 and y1 are the ordered pair.

The question gives us a equation of the line in slope intercept form: $y=mx+b$

When:

M is the slope

B is the y-intercept.

We can use the equation $y=-\frac{2}{3}x+6$ to determine the slope.

-2/3 replaces m, so that is the value of the slope.

We can now use the slope and the points to create the point slope equation.

m= -2/3

x1, y1 = (-3,8)

Plug in the information:

$y-8=-\frac{2}{3}(x+3)$

Express -48 by 60 as a rational number with denominator 25 pura Karen

Andre45 [30]

Answer:

-20/25

Step-by-step explanation:

To change a fraction to one with a different denominator, common factors can be removed or added to numerator and denominator as required.

-48/60 can be reduced to lowest terms by removing the common factor of 12. It can be made to have a denominator of 25 by adding a common factor of 5.

$-\dfrac{48}{60}=-\dfrac{4\cdot12}{5\cdot12}=-\dfrac{4}{5}\\\\=-\dfrac{4\cdot5}{5\cdot5}=\boxed{-\dfrac{20}{25}}$

Alternatively, the numerator of the desired fraction can be found by multiplying the given fraction by the desired denominator.

numerator = 25×(-48/60) = -1200/60 = -20

new fraction = -20/25
