Answer:

<h2>D) X = 16/3 - 4y/3 </h2>

Explanation

3x + 4y = 16

3x = 16 - 4y

3x = 4 ( 4 - y)

x = 4(4 - y)/3

X= 16 /3 - 4y/3

Answer:

3x + 4y = 16  The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 4y.

3x = -4y + 16  Divide by 3.

x = -4y/3 + 16/3  Answer B.

masya89 [10]

Answer:

APR = 416%

EAR = 5370.60%

Step-by-step explanation:

Given:

Interest rate = 7.8% per week

Now,

In an year there are total 52 weeks

thus,

The APR (Annual percentage rate) = Interest rate × Total weeks in an year

or

APR = 8% × 52

or

APR = 416%

and, EAR ( Effective Annual Rate ) = ( 1 + r )ⁿ - 1

Here,

r is the interest rate per week

n is the total weeks in an year

thus,

EAR ( Effective Annual Rate ) = ( 1 + 8% )⁵² - 1

= ( 1 + 0.08 )⁵² - 1

= 53.7060

or

53.7060 × 100% = 5370.60%

Scientists are studying the temperature on a distant planet. They find that the surface temperature at one location is 40° Celsi
jok3333 [9.3K]

Answer:

T(h) = 20 - 3h

Step-by-step explanation:

We are told that for every km you go up, the temp goes down 3°.

Let's say you go up 1km, then the temp should be 17°. We can easily represent it by the equation: T(h) = 20 - 3h

If we go up 1km: T(1) = 20 - 3*(1) = 20 - 3 = 17°

If we go up 2km: T(2) = 20 - 3*(2) = 20 - 6 = 14°

If we go up 3km: T(3) = 20 - 3*(3) = 20 - 9 = 11°

The sides of a triangle are in the ratio 3 4 5. what is the length of each side if the perimeter of the traingle is 30 cm?
Margaret [11]
Since both triangles are similar triangles, you are able to find the scale factor through the perimeter.

Perimeter of the 3 4 5 triangle is 12cm.
Scale factor = 30/12
= 2.5

Multiply the scale factor with the 3 4 5 triangle.
3 x 2.5 = 7.5 cm
4 x 2.5 = 10 cm
5 x 2.5 = 12.5 cm

To summarize, all 3 new values should sum up to 30cm.
