Answer:

When x= 7/3, y = 2.

Step-by-step explanation:

When two variables are inversely related, it means that if one variable increases, the other one decreases. This relationship can be expressed as:

y = k/x, where "x" and "y" are variables and "k" the proportionality constant.

As the problem states, if y= 7 then x = 2/3. Now we can find the value of the constant "k"

7 = k/(2/3) ⇒ 7 x (2/3) = k ⇒ 14/3 = k.

So the equation for "x" and "y" ⇒ y = 14/3x

Finally you have to replace x = 7/3

⇒ y = 14/[3 x (7/3)] ⇒ y = 2.

Summarizing, when x = 7/3, y = 2.

Y=k/x
7=k/(2/3)
7=k(3/2)
times both sides by 2/3
14/3=k

y=(14/3)/x
y=(14/3)/(7/3)
y=(14/3)(3/7)
y=2

The question states that both parts of Noshi's desk were shaped like trapezoids and both had a height of 3.

We know that the formula for area of a trapezoid is (a+b)/2 * h, where a and b are bases of the trapezoid and h is the height. Note: This is like any other form of trying to find the area, because we are doing base times height, however, we need to divide the sum of the bases by 2 to find the average base length.

Let's call the first trapezoid on the left Trapezoid A and the second slanted trapezoid Trapezoid B.

Area of Trapezoid A = (a+b)/2 * h = (5+8)/2 * 3 = 13/2 * 3 = 6.5 * 3 = 19.5 feet
Area of Trapezoid B = (a+b)/2 * h = (4+9)/2 * 3 = 13/2 * 3 = 6.5 * 3 = 19.5 feet

To find the area of Noshi's total desk, we simply need to add the areas of Trapezoid A and Trapezoid B together.

19.5 feet + 19.5 feet = 39 feet

Therefore, the area of Noshi's desk is 39 feet.

Hope this helps! :)

in a certain store, the regular price of a refrigerator is $600. how much money is saved by buying the refrigerator at 20% off t
Advocard [28]
60$. These are my equations :
600 * 0.2 = 120 ; 600 - 120 = 480
Then...
600 * 0.1 = 60 ; 600 - 60 = 540
Which then became....
540 - 480 = 60

What is -3+5+6g=11-3g solve for g
vitfil [10]

Answer: g = 1

Step-by-step explanation:

-3 + 5 + 6g = 11 - 3g

First, we need to combine like terms

-3 + 5 = 2

2 + 6g = 11 - 3g

Add 3g to each side

2 + 9g = 11

Subtract 2 from each side

9g = 9

Divide each side by 1

g = 1
