Answer:

x = 11

Step-by-step explanation:

Answer:

x = 11

Step-by-step explanation:

3x -5 = 2x +6

add 5

3x -5 +5 = 2x +6 +5 =

3x = 2x +11

subtract 2x

3x - 2x = 2x - 2x +11 =

1x = 11

divide by 1

1x/1 = 11/1 =

x = 11

Answer:-2n+12

Step-by-step explanation: Distribute -2

Answer:

-2n=12 or -2n-(-12)

Answer:

440 tigers per year

Step-by-step explanation:

It says that over 5 years the population decreased by 2200, so 2200 divided by 5 would be 440.

Answer:

2200/5 = 440 per year

Answer:

4

Step-by-step explanation:

first substitute 1 on the x on the function

which is -2(1)²+ 2(1) + 4

then next simplify to -2 + 2 + 4

when you add the answer is 4

This is the same as 9pi/2 or (9/2)pi

===================================================

Explanation:

A full circle has area

A = pi*r^2

Since the radius is r = 3, we know that

A = pi*r^2

A = pi*3^2

A = pi*9

A = 9pi

is the area of the full circle with radius 3.

But we have a semicircle here, so we need to cut this area in half

9pi/2 = (9/2)pi = 4.5pi

Answer:

9pi

Step-by-step explanation:

A=pi r ^2 / 2

25x+>34 is the correct answer.

The correct answer is option A.

An equation is a mathematical declaration this is made up of two expressions linked through the same sign. As an example, 3x – five = 16 is an equation. solving this equation, we get the cost of the variable x as x = 7.

Answer:

34 minutes

Step-by-step explanation:

Given:

Ratio of time for which Pepperoni pizza and cheese pizza should be baked is given as:

[tex]P = 3C - 2[/tex]

Where [tex]P[/tex] is the time for which pepperoni pizza should be baked and

[tex]C[/tex] is the time for which Cheese pizza should be baked.

Also, it is given that a small Cheese pizza should be baked for 12 minutes.

In other words, we are given that: [tex]C=12\ min[/tex]

To find:

For how long small pepperoni pizza should be baked ?

In other words,

[tex]P=?[/tex]

Solution:

Let us put the value of [tex]C[/tex] in the equation of the model.

[tex]P = 3C - 2[/tex]

[tex]\Rightarrow P = 3\times 12 - 2\\\Rightarrow P = 36 - 2\\\Rightarrow P = \bold{34\ min}[/tex]

Therefore, a small pepperoni pizza should be baked for 34 minutes.

Answer:

48

Step-by-step explanation:

because I had times 12 and 4 to get 48

Answer:

the answer is 32

Step-by-step explanation:

12-4=8

add 8 and 4 you'll get 12. Subtract 4 from 8 you'll get 4.

multiply 8 and 4 you'll get 32

Just do what i put up there

===============================================

Explanation:

The sequence 2,8,32,128,... is geometric

To get a new term, we multiply by the common ratio 4.

2*4 = 8

8*4 = 32

32*4 = 128

To find the common ratio, you pick any term you want, and divide by its previous term

r = (term2)/(term1) = 8/2 = 4

r = (term3)/(term2) = 32/8 = 4

r = (term4)/(term3) = 128/32 = 4

The starting term is a = 2, so the nth term is

a(n) = a*(r)^(n-1)

a(n) = 2*(4)^(n-1)

Step-by-step explanation:

6x - 3y = -6

=> 3(2x - y) = -6

=> 2x - y = -2

And you see there's a problem here. The question doesn't have enough information because x and y can be every numbers.

Take an example, x can be 200 and y can be 402 or x can be 5 and y can be 12.

Answer:

20

Step-by-step explanation:

Number of juniors = 80

Number of seniors = 100

To obtain the same and highest number of student on each float ; we find the highest common factor :

____80 ___100

_2__40___50

_2__20___25

_5__ 4____5

The highest common factor = (2 * 2 * 5) = 20

Answer:

69.4 pounds

Step-by-step explanation:

Answer:

The first one.

Step-by-step explanation:

I believe the correct answer is the first one on the list because the variable, R, is 6 ticks below 0. How I got that was by going to 0 and counting down 6 lines and thats where R was located.

Answer:

Second

Step-by-step explanation:

Because, according to the question we are searching for the opposite of R. So, a distance of 6 and marks above 0 represent the positive side, so the opposite.

Answer:

It takes 9 or more months for the Apartment B to pay less than Apartment A.

Step-by-step explanation:

Apartment B:

8 x 350 = $2800

$2800 + $500 = $3300

----------------------------------------------

9 x 350 = $3150

$3150 + $500 = $3650

Apartment A:

$400 x 8 = $3200

$3200 + $100 = $3300

----------------------------------------------

9 x 400 = 3600

3600 + 100 = 3700

Answer:

slope = 4

Step-by-step explanation:

Parallel lines have equal slopes.

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 5 = 4(x + 3) ← is in point- slope form

with slope m = 4

A parallel line has a slope of 4

Answer:

m+5<40

Step-by-step explanation:

40 is greater than 5=<

[tex]D=b^2-4ac\\D=(-2)^2-4(8)(-1)\\D=4+32\\D=36[/tex]

For another information, when D > 0, there are 2 real roots.

When D = 0, there is only one real root.

And when D < 0, there are no real roots (also known as imaginary.)
