Answer:

2x+3

Step-by-step explanation:

2x is twice a number and +3 is three more than that number.

Answer:

x = -11

Step-by-step explanation:

To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.

-11 + 4 = -7

(-7)^2 = 49

Answer:

x = -11

Step-by-step explanation:

To get to 49 by squaring, you need to square 7. Since x can only be negative, you need to get to -7.

Answer:

-1/2

Step-by-step explanation:

3/2 x 5/3 ÷ (-2+7)

=> 3/2 x 5/3 ÷ (-5)

=> 3/2 x 5/3 x (-1/5)

=> -1/2

Answer:

463

Step-by-step explanation:

Division is repeated subtraction

So to get 0, we divide 20835 by 45

=> 20835/45

=> 463

Answer:

25.7

Step-by-step explanation:

PQ=PR-QR

PQ=38.3-12.6

PQ=25.7 cm

Answer: PQ = 25.7 cm

Concept:

Here, we need to know the idea of the segment addition postulate.

The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Solve:

Given information

PR = 38.3 cm

QR = 12.6 cm

Given expression deducted from the segment addition postulate

PQ = PR - QR

Substitute values into the expression

PQ = (38.3) - (12.6)

Simplify by subtraction

PQ = [tex]\boxed{25.7cm}[/tex]

Answer:

18 m

Step-by-step explanation:

Hi there!

We're given:

⇒ The plant is already 12 m tall

⇒ It grows 20 cm every month

First, we must convert everything into the same unit. Divide 20 cm by 100 to convert it to meters:

20 ÷ 100 = 0.2

Now, we can form this equation:

Plant Height = 12 m + (0.2 m × number of months)

Let plant height be h and number of months be m:

[tex]H=12+0.2m[/tex]

To find the plant's height after 30 months, replace m with 30:

[tex]H=12+0.2(30)\\H=12+6\\H=18[/tex]

Therefore, the plant would be 18 m tall.

I hope this helps!

Answer:

2n + 11

Step-by-step explanation:

2(1) + 11 = 13

2(2) + 11 = 15

2(3) + 11 = 17

the 2 is the constant difference between the first 2 terms.

the numbers in brackets are the term number.

you have to multiply the difference with the term number.

then you will have to take that answer and subtract it from the first term number.

Answer:

m = 1.08

Step-by-step explanation:

2 - 2.27 = -m/4

-0.27 = -m/4

-0.27 × 4 = -m

-1.08 = -m

1.08 =m

Answer:

m = 1.08

Step-by-step explanation:

Basically, we can start off by finding the difference between 2 and 2.27(which is 0.27). Then we can see that 0.27 is equal to m/4. Since 0.27*4=1.08, we can see that m=1.08.

Answer:

x  = 4

Step-by-step explanation:

Let the number = x

x^3 = x^2 + 48

x^3 - x^2 - 48 = 0

The answer is 4, but I have no method of doing this rigorously. I can just show that it is true.

x^3 = 4^3 = 64

x^2 = 4^2 = 16

64 - 48 = 16
