Answer:

area: A = 8 m^2

Step-by-step explanation:

Area of a rectangle:  A = ab

Answer:

n x p = c

Step-by-step explanation:

n is the amount of pens so we time it by the cost of 1 pen which is p and the final answer is c as the cost of all the pen.

Answer:

a) y=1/3x-2

b) y=1/5x+2

c) y=[tex]\sqrt{x}[/tex]

Step-by-step explanation:

Step-by-step explanation:

18. y-(-2) = -6(x-2)

y+2 = -6x+12

y = -6x+12-2

y = -6x+10

19. y-(-4) = -½(x-4)

y+4 = -½x+2

y = -½x+2-4

y = -½x-2

Answer:

x = 0

Step-by-step explanation:

-1 +3(x + 2) = 5(1 + 8x)

-1 +3x +6 = 5 + 40x

3x + 5 = 5 + 40x

3x - 40x = 5 - 5

-37x = 0

x = 0

Answer:

JT = 29

Step-by-step explanation:

CT=CJ+JT

69= (4x+8)+ ( 3x+5)

69= 7x +13

7x= 69-13

7x= 56

x=56/7

x=8

JT=3x+5=3(8)+5= 24+5=29

I hope I helped you^_^

Step-by-step explanation:

EF = 6x - 4

and it is also the combination of EG and GF.

so,

6x - 4 = EG + GF = EG + 13

6x = EG + 17

now, we have additional information. EF bisects CD. that means it cuts CD in half.

and that means both banks must be off equal size.

5x - 1 = 7x -13

12 = 2x

x = 6

so, back to the first problem

6×6 = EG + 17

36 = EG + 17

19 = EG

uhm wait cz I think I had made a mistake and I need to fix it

Answer:

They are all right

Step-by-step explanation:

all of them are right

Everything is correct except the last one. I have attached the solutions, see them.

We can write S as

[tex]\displaystyle S = \sum_{k=0}^{n-1} (n-k)3^k[/tex]

and expand it as

[tex]\displaystyle S = n \sum_{k=0}^{n-1} 3^k - \sum_{k=0}^{n-1} k\cdot3^k[/tex]

The first sum is geometric, nothing tricky:

[tex]\displaystyle\sum_{k=0}^{n-1} 3^k = 1 + 3 + 3^2 + \cdots + 3^{n-1} \\\\ \implies 3\sum_{k=0}^{n-1} 3^k = 3 + 3^2 + 3^3 + \cdots + 3^n \\\\ \implies -2\sum_{k=0}^{n-1} 3^k = 1 - 3^n \\\\ \implies \sum_{k=0}^{n-1} 3^k = \frac{3^n-1}2[/tex]

For the second sum, you can use the same method employed in another question of yours (24494877) to find

[tex]\displaystyle \sum_{k=0}^{n-1} k\cdot 3^k = \frac{(2n-3)3^n+3}4[/tex]

So this sum comes out to

[tex]\displaystyle S = n\cdot\frac{3^n-1}2 - \frac{(2n-3)3^n+3}4 \\\\ S = \frac{2n\cdot3^n-2n - (2n-3)3^n-3}4 \\\\ \boxed{S = \frac{3^{n+1}-2n-3}4}[/tex]

I think second would be better because there is no charges for per day and then it will be cheaper than the car rental value

Step-by-step explanation:

taxi rates $ 6.50 for the first mile plus for each additional mile

because it is cheaper.

Answer:

5x + 13

Step-by-step explanation:

x times 5 is 5x.

13 more than 5x is 5x + 13, or 13 + 5x. (Same thing.)

The required expression is 5x + 13.

It is required to find the required expression.

An expression is a set of terms combined using the operations +, – , x or ÷. An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An expression is in simplest form when no terms can be combined.

Given:

The given problem is 13 more than x times 5.

According to given question we have,

x times 5 is 5x.

13 more than 5x

= 5x + 13

Therefore, the required expression is 5x + 13.

Answer:

Y=1x+0

Step-by-step explanation:

Simple y1-y2 over x1-x2 so...

2-(-2)=4

2-(-2)=4

So Slope of 1 then you pick any coordinate on the line and sub in the y. So I choose (0,0) cuz ya know easy.

SO...

Y=1x+0

Science, any system of knowledge that is concerned with the physical world and its phenomena and that entails unbiased observations and systematic experimentation. In general, a science involves a pursuit of knowledge covering general truths or the operations of fundamental laws.

Step-by-step explanation:

Qualitative data are discrete, for instance, "Yes/No" type questions. They are usually presented in bar charts or pie charts to show the portion of different populations with certain characteristics in a single experiement (e.g. Not allergic to ginger VS allergic to ginger).

Qualitative data are usually continuous, and can show a trend or distribution numerically. They are usually presented by, for instance, line charts (e.g. Distribution of resident age in block E)

Answer:

2(2y+5)/2=37.2/2

2y+5=37

2y+5-5=37-5

2y=32

2y/2=32/2

y=16

the closest to that is y=8

Step-by-step explanation:

hope that helps>3

Answer:

let that man's age be x :

[tex]300 - 3x = 6[/tex]

subtract 300 from both sides:

[tex](300 - 3x) - 300 = 6 - 300 \\ - 3x = - 294[/tex]

apply the division rule of equality:

[tex] \frac{ - 3x}{ - 3} = \frac{ - 294}{ - 3} \\ \\ x = 98[/tex]

The man is 98 years

Answer:

the man is 98 years old.... please give me brainliest

Step-by-step explanation:

[tex]300 - 3 \times x = 6 \\ 300 - 3x =6 \\ - 3x = 6 - 300 \\ - 3x = - 294 \\ divide \: both \: sides \: by \: - 3 \\ - 3x \div 3 = 294 \div 3 \\ x = 98[/tex]

Step-by-step explanation:

Answer:

$y=(7/2)x+20$

Step-by-step explanation:

SInce the gradient of the first line is $-2/7$ then the gradien of the perpendicular line is $7/2$.

Therefore by the point slope formula the line that we are looking for is

$y-6=(7/2)(x+4)$

$y=(7/2)x + 20$

Answer:

A4=-37
