Answer:

-24/35

Step-by-step explanation:

Division of fractions is equivalent to multiplication by the reciprocal of the second fraction.

Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:

12/15 ÷ 7/6 = 12/15 x 6/7

The Greatest Common Factor (GCF) of 72 and 105 is 3. The result can be simplified by dividing both the numerator and denominator by 3.

8. Nate bought two large pizzas and one small pizza and paid $36. If the difference in cost between a large and small pizza is $

s344n2d4d5 [400]

Answer:

$8.5

Step-by-step explanation:

We need to propose a system of equations with the information provided to us.

two large pizzas and one small pizza cost $36:

$2L+S=36$

where

$L$ : Large pizza

$S:$ Small pizza

and the difference in cost between a large and small pizza is $5.25:

$L-S=5.25$

our system of equations is:

$2L+S=36$

$L-S=5.25$

We are asked for the price of small pizza, so we must manipulate the equations in such a way that adding or subtracting them removes the variable L and we are left with an equation for S.

Multiply the second equation of the system by -2

$(-2)(L-S=5.25)\\\\-2L+2S=-10.5$

and now we sum this with the first equation of the system:

$-2L+2S=-10.5\\+(2L+S=36)\\-------------\\-2L+2L+2S+S=-10.5+36$

simplifying the result:

$3S=25.5$

and solving for S (the price of a small pizza)

$S=25.5/3\\S=8.5$

What is through :(0,5) and (-5,2)

Murljashka [212]

Answer:

y = 3/5x + 5

Step-by-step explanation:

Gradient of the line

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\\\\frac{2 - 5}{-5 - 0}\\\\\frac{-3}{-5}$

$\frac{3}{5}$

y = 3/5x + c

Substitute either point in to find c

y = 3/5x + c at (0,5)

5 = 3/5(0) + c

5 = 0 + c

5 = c

y = 3/5x + c at (-5,2)

2 = 3/5(-5) + c

2 = -3 + c

2 + 3 = c

5 = c

y = 3/5x + c

Replace c with 5

y = 3/5x + 5
