Answer:

x=-6.8

[tex] \\ step \: by \: step \: explanation \\ \frac{11}{(x + 9)} = 5 \\ 11 = 5(x + 9) \\ 11 = 5x + 45 \\ 5x = 11 - 45 \\ 5x = - 34 \\ x = \frac{ - 34}{5} = - 6.8[/tex]

Answer:

[tex]x = \frac{39}{2}[/tex]

[tex]y = -\frac{29}{2}[/tex]

Step-by-step explanation:

Given

[tex]x + y= 5[/tex] --- (1)

[tex]7x + 9y = 6[/tex] ---- (2)

Required

Find x and y

Make x the subject in (1)

[tex]x + y= 5[/tex]

[tex]x = 5 - y[/tex]

Substitute 5- y for x in (2)

[tex]7x + 9y = 6[/tex]

[tex]7(5 - y) + 9y = 6[/tex]

Open bracket

[tex]35 -7 y + 9y = 6[/tex]

Collect like terms

[tex]-7y + 9y = 6 - 35[/tex]

[tex]2y = -29[/tex]

Divide both sides by 2

[tex]y = -\frac{29}{2}[/tex]

Substitute this for y in [tex]x = 5 - y[/tex]

[tex]x = 5 - (-\frac{29}{2})[/tex]

[tex]x = 5 +\frac{29}{2}[/tex]

L.C.M

[tex]x =\frac{10+29}{2}[/tex]

[tex]x = \frac{39}{2}[/tex]

A perfect square is a number whose product value is an integer. If you change any integer you will always get a even number.

Step-by-step explanation:

Answer:

17 horses and 19 geese

Step-by-step explanation:

Let x be the number of horses and y be the number of geese

We know that, horses have four feet and geese have 2 feet

It is given that

x+y=36 (i)

and

4x+2y=106 (ii)

Solve the two equations simultaneously by substitution,

From equation (i)

y=36-x (iii)

Substitute y with 36-x in equation (ii)

4x+2(36-x)=106

4x+72-2x=106

4x-2x=106-72

2x=34

x=17

Then

Substitute x=17 to equation (iii)

y=36-17=19

x=17, y=19

We therefore have 17 horses and 19 geese

Hey there!

The answer is n - 1.

Let's pretend the number is 15, so 1 less than "15", if you think about it, would be 14, and to get there, you do 15 - 1, now let us switch "15" back to a number "n", and now we have "n - 1"

Answer:

2.57 yards longer

Step-by-step explanation:

Step one:

given data

We are told that the Jiaozhou Bay Bridge in China, spans 26.4 miles

Also, The longest sea bridge in the United States is the Lake Pontchartrain Causeway in Louisiana, which spans 41,940 yards

Required

Unit conversion from yards to miles

Step two:

let us convert 41,940 yards to miles

We know that 1 yard is 0.000568182 miles

hence 41,940 yards is x miles

cross multiply we have

x= 41,940*0.000568182

x=23.83 yards

Hence the difference in their lengths is

=26.4-23.83

=2.57 yards

Formula

[tex]y - 3 = \frac{2}{3} (x - 2)[/tex]

Write in standard form

[tex]2x - 3y = - 5[/tex]

Answer:

40 and 35

Step-by-step explanation:

If we say the first car uses x gallons then the second car must use 75 - x gallons.

The distance travelled is the number of gallons used * the efficiency of the car.

20x + 15(75-x)=1325

20x + 1125 - 15x = 1325

5x = 200

x = 40

This means that the first car uses 40 gallons and the second car uses 75-40= 35 gallons

Step-by-step explanation:

We first section off all the areas we can, find the area of each of those, add them all up, and you get 252 inches.

[tex]3(4 - 2x) = - 2x[/tex]

[tex]12 - 6x = - 2x[/tex]

[tex]12 = - 2x + 6x \\ 12 = 4x \\ \frac{12}{4} = x \\ 3 = x[/tex]

[tex]3(4 - 2x) = - 2x \\ 3(4 - 2(3)) = - 2(3) \\ 3(4 - 6) = - 6 \\ 3( - 2) = - 6 \\ - 6 = - 6 \: \: \green{ \checkmark}[/tex]

Answer:

Equation: r-20=74

Step-by-step explanation:

So he started with 94. I got B

Given the equation: - 4 √x - 3 = 12

solve for x;

Divide both sides by -4 in [1];  we get;

√x - 3 = -3

Squaring both sides we get;

x -3 = (3)²

or

x - 3 = 9

Add 3 both sides we get;

x - 3 + 3 = 9 + 3

Simplify:

x= 12

Extraneous solution states that it is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation.

Substitute  x= 12 in [1]

- 4√12 - 3 = 12

- 4√9 = 12

-4. 3 = 12

-12 = 12 False.

Therefore, the value of x is 12 and it is an extraneous solution.

Answer:

The second pack with 18

Step-by-step explanation:

2.97/11= 0.27

4.74/18=0.26333

Answer: You should probably go for the $4.74

Step-by-step explanation:

Because you can pay that price and get 18 slices, but on the other hand,  if you get the other you would be paying 2.97 for only ONE package of sliced cheese. So you would pay for the $4.74 package of cheese to get more for your money.
