If (x+28y)/x=50 then what does (y+28x)/y=
tankabanditka [31]

Answer:

17

Step-by-step explanation:

(x+28y)/x =50

Multiply each side by x

(x+28y)/x *x =50*x

x+28y = 50x

Subtract x

x-x+28y = 50x-x

28y = 49x

Divide by y

28y/y = 49x/y

28 = 49 x/y

Divide by 49

28/49 = x/y

We want to find

(y+28x)/y

Rewriting as

y/y +28 (x/y)

1 + 28(x/y)

Replacing x/y with (28/49)

1 + 28(28/49)

1 +28*28/49

1+784/49

1+16

#19 please I’m literally failing math
ankoles [38]

Answer:

$51.12

Step-by-step explanation:

Hello there!

In number 19, we want to find the total price of a sweatshirt that costs $48 dollars but has 6.5% sales tax

Sales tax is a small percentage of the cost of an item that is added to items when they are being sold.

In this problem, 6.5% of the cost of the sweatshirt will be added to the cost of the sweatshirt in the form of sales tax. The price of the sweatshirt plus the amount in sales tax will be the total cost of the sweatshirt.

Translating that as an equation,

48 + 48*6.5%=total cost

You can calculate 48*6.5% as \frac{48*6.5}{100}, which is equal to 3.12

So that means that $3.12 will be added to the cost of the sweatshirt.

Therefore,

48 + 3.12=<u>$51.12</u>, which will be the total cost of the sweatshirt, including sales tax

Hope this helps!

son4ous [18]

Answer:

13\frac{1}{3}\ in

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produces similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

step 1

Find the scale factor

Let

z ----> the scale factor

z=\frac{10}{6} ----> ratio of corresponding sides

simplify

z=\frac{5}{3}

step 2

Find the length of the enlarged design (L)

Multiply the length of the original design by the scale factor

so  

L=\frac{5}{3}(8)=\frac{40}{3}\ in

Convert to mixed number

\frac{40}{3}\ in=\frac{39}{3}+\frac{1}{3}=13\frac{1}{3}\ in
