Use a graph to solve
on the X side you input all the length values and on the Y side input all the width values, then you’ll see a pattern
every time the x value goes up by 2, the y value goes up by 5
the last x value was 16 correlating with a y value of 40 so to get to 24 you add 8 to the x value, which means you would add 20 to the y value (y/2 times 5)
that means the length is 24 and the width is 60

6x + 5y = 4<br> - 6x + y = 20

Masja [62]

Answer:

x = -8/3

y = 4

Step-by-step explanation:

I assume you want to solve for x and y.

The best way to do this with the two formulas given is elimination. This means add the two equations together.

6x + 5y = 4

-6x + y = 20

The 6 x and -6x will cancel each other. By adding the like terms of the two together you will come out with

6y = 24

Now solve for y by dividing both sides by the 6.

y = 24/6 = 4

Now that we have y, you can plug it into one of the equations and solve for x.

Let's use -6x + y =20.

So plug in the 4 for y to get -6x + 4 = 20

Subtract the 4 from both sides then solve for y by dividing both sides by the -6.

-6x = 16

x = -16/6

You can reduce that down so that x = -8/3.

Geometric mean <br> Pls help thank u

quester [9]

Answer:

Step-by-step explanation:

1). Geometric mean of a and b = $\sqrt{a\times b}$

Therefore, geometric mean of 2 and 50 = $\sqrt{2\times 50}$

= 10

2). By geometric mean theorem,

$\frac{JM}{KM}=\frac{KM}{ML}$

$\frac{6}{e}=\frac{e}{24}$

e² = 6 × 24

e = √144

e = 12

Similarly, $\frac{JL}{KJ}=\frac{KJ}{JM}$

$\frac{6+24}{d}=\frac{d}{6}$

d² = 6 × 30

d = √180

d = 6√5

And $\frac{JL}{KL}=\frac{KL}{ML}$

$\frac{6+24}{c}=\frac{c}{24}$

c² = 30 × 24

c = √720

c = 12√5

URGENTEE. NON SO RISOLVERE QUESTO PROBLEMA.

Marrrta [24]

the question in English

Draw a rectangle having the base congruent to the nine sevenths of the height.

Let

b-------> the base of rectangle

h-------> the height of rectangle

we know that

b=(9/7)*h-------> this is the equation to obtain the base of the rectangle for a given height

examples

1) for h=7 units

b=(9/7)*7-------->b=9 units

the dimensions are 9 units x 7 units------> see the attached figure

2) for h=5 units

b=(9/7)*5-------->b=(45/7) units

the dimensions are (45/7) units x 5 units

The answer in Italian

Facciamo

b-------> base del rettangolo

h-------> altezza del rettangolo

Noi sappiamo che

b=(9/7)*h-------> questa è l'equazione per ottenere la base del rettangolo per una determinata altezza

esempi

1) per h=7 units

b=(9/7)*7-------->b=9 units

le dimensioni sono 9 units x 7 units-----> vedere la figura allegata

2) per h=5 units

b=(9/7)*5-------->b=(45/7) units

le dimensioni sono (45/7) units x 5 units
