Answer:

w = 10.4

Step-by-step explanation:

step 1 - You add 16 and 4 which is 20

Step 2 - Than you subtract 20 from both sides so it will be 20 - 20 = 0 and 27.28 - 20 = 7.28

Step 3 - Now you take 7.28 ÷0.7 = 10.4

So the answer is 10.4

Write a proportion for each of the following equations and perform all changes: a 2·9=3·6

just olya [345]

$\boxed{\frac{2}{3}=\frac{6}{9}}$

Step-by-step explanation:

The equation we are given is the following:

$2\cdotp9=3\cdotp6$

A proportion is a relationship between two ratios. This tells us that two ratios are equal. That is, suppose you have two ratios:

$(1) \ \frac{a}{b} \\ \\ (2) \ \frac{c}{d}$

Then, we can write a proportion as follows:

$\frac{a}{b}=\frac{c}{d}$

For:

$2\cdotp9=3\cdotp6$

If you divide both sides by (3)(9):

$\frac{1}{3\cdotp9}(2\cdotp9)=\frac{1}{3\cdotp9}(3\cdotp6) \\ \\ \boxed{\frac{2}{3}=\frac{6}{9}}$

Step-by-step explanation:

Add all of the inches together including the parts you don't see.

one side is 9 inches. there are 8 sides. so 9x8. One side in the box is 7 inches. there are 4 sides. so 7x4. 9x8 + 7x4 is equal to 72 + 28.

72 + 28=100

Can someone help me on this question please

IgorLugansk [536]

Answer:

y = -2x + 5 [ 1st option ]

Step-by-step explanation:

Consider any two points , say

(1,3)
(2,1)

Firstly let's find the slope of the line as ,

=> m = y₁ - y₂ / x₁ - x₂

=> m = 3-1 / 1-2

=> m = 2/-1

=> m = -2

Third point is, (3 , -1) . Using slope point form .

=> y - y₁ = m ( x - x₁ )

=> y - (-1) = -2( x - 3)

=> y + 1 = -2x +6

=> y +2x +1-6=0

=> y +2x -5 = 0

=> y = -2x + 5

On looking at options first one is correct

<h3>Hence the equation of line is y = -2x + 5.</h3>
