\dfrac{4}{z}=\dfrac{12}{5}\\\\ 12z=20\\\\ z=\dfrac{20}{12}=\dfrac{5}{3}

Step 1: 4/z = 12/5 (original question)

Step 2(cross-multiply): 4(5) = z(12)

Step 3: 20 = z(12)

Step 4: 20 = 12z

Step 5: 12 = 20

Step 6: Divide both sides by 12.

Step 7: z = 20/12

Step 7(reduce the fraction): z = 3/5 <<<Answer

I hope this assisted you! Good luck! :)

Noah pays $25.20 for non-perishable food items to give to the local homeless shelter the price includes a 5% sales tax.
Alexandra [31]

The question is incomplete:

Noah pays $25.20 for non perishable food items to give to the local homeless shelter the price includes a 5% sales of tax. what is the price before tax of the food items?

Answer:

$24

Step-by-step explanation:

From the information you have that the price of items is $25.20 and it includes a 5% tax. From this, you can write the following:

x+0.05x=25.20

Then, you can isolate x to find the price before tax:

1.05x=25.20

x=25.20/1.05

x= 24

According to this, the price before tax of the food items is $24.

Determine which line the point (2, -1) lies on. y = 2x + 1 y = x + 5 y = 2x - 5 y = x - 2
inna [77]

To determine which line the point lies on, you can just plug in one of the numbers into the equations to see if it equals out.

(2, -1)  I will use the 2 and plug it in for x in the equation.

y = 2x + 1

y = 2(2) + 1

y = 5            The point does not lie on this line because when x = 2, y = 5  (2, 5)

y = x + 5

y = 2 + 5

y = 7          The point does not lie on this line because when x = 2, y = 7  (2, 7)

y = 2x - 5

y = 2(2) - 5

y = 4 - 5

y = -1           The point does lie on this line because when x = 2, y = -1  (2, -1)

y = x - 2

y = 2 - 2

y = 0      The point does not lie on this line because when x = 2, y = 0  (2, 0)
