please help me !!!!!!!!

[tex]\qquad\qquad\huge\underline{{\sf Answer}}[/tex]

let's solve ~

The given equations are :

[tex]\qquad \tt \dashrightarrow \:5x + 3y = 7 \: \: \: \: \: \: \: \: \: \: \: \: - (1)[/tex]

and

[tex]\qquad \tt \dashrightarrow \:3x - 5y = - 23 \: \: \: \: \: \: - (2)[/tex]

Now, let's multiply equation (1) by 5 and equation (2) by 3 ~

we will get the results as :

[tex]\qquad \tt \dashrightarrow \:25x + 15y = 35 \: \: \: \: - (3)[/tex]

[tex]\qquad \tt \dashrightarrow \:9x - 15y = - 69 \: \: \: - (4)[/tex]

Now, add equation (3) and (4) :

[tex]\qquad \tt \dashrightarrow \:25x + \cancel{ 15y} + 9x - \cancel{15y }= 35 + ( - 69)[/tex]

[tex]\qquad \tt \dashrightarrow \:34x = - 34[/tex]

[tex]\qquad \tt \dashrightarrow \:x = - 1[/tex]

Now, since we got the value of x, let's evaluate y~ by using equation (1) :

[tex]\qquad \tt \dashrightarrow \:5x + 3y = 7[/tex]

[tex]\qquad \tt \dashrightarrow \:5( - 1)+ 3y = 7[/tex]

[tex]\qquad \tt \dashrightarrow \:3y - 5 = 7[/tex]

[tex]\qquad \tt \dashrightarrow \:3y = 12[/tex]

[tex]\qquad \tt \dashrightarrow \:y = 4[/tex]

Hence, value of y is 4

I hope you understood the whole procedure ~

Answer:

$ 1349.746624

Step-by-step explanation:

The volume of a cylinder

The formula for calculating the volume of a cylinder is expressed as:

V=πr²h

where:

r is the radius

h is the height

Given the following parameters

r = d/2 = 1.5/2 = 0.75ft

h = 30ft

Get the volume of the cylinder

V=π(0.75)²(30)

V= 53.0144...ft³

If the wod costs $25.46 per cubic foot, hence the cost of the wood will be 53.0144*25.46 = $ 1349.746624

Answer:

i believe the answer is B, im not 100% though

Step-by-step explanation:

Answer:

n = 17

Step-by-step explanation:

The difference between the 5th and 6th terms is 13 - 11 = 2

Therefore, the next term can be found by adding 2 each time.

If we continue with this sequence, we get:

5 = 11

6 = 13

7 = 13 + 2 = 15

8 = 15 + 2 = 17

9 = 17 + 2 = 19

10 = 19 + 2 = 21

So n = 17

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

Arithmetic sequence

General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

where:

Given terms of the sequence:

[tex]a_5=11\\a_6=13\\a_8=n\\a_{10}=21[/tex]

The common difference can be found by subtracting one term from the next term:

[tex]d=13-11=2[/tex]

To find a, substitute the found value of d into the equation for one of the given terms:

[tex]\begin{aligned}a_5 =a+(5-1)2 & =11\\ a+8 & =11\\ a & = 3\end{aligned}[/tex]

Therefore, the formula to find the nth term is:

[tex]\implies a_n=3+(n-1)2[/tex]

[tex]\implies a_n=2n+1[/tex]

So, the 8th term is:

[tex]\implies a_8=2(8)+1=17[/tex]

Answer:

X=35

Step-by-step explanation:

all angles on a straight line equal 180 degrees

there fore the equation for x will be,

180= 40+(2X+30)+40

180=40+ 2X +30+40

180 =2X+110

180-110=2X

70=2X

70/2=X

35=X

The expression P(B|C) is an illustration of probability, and the value of P(B|C) is 0.38

From the question, we have the following highlights:

n(B and C) = 9

n(C) = 24

The equation to calculate the probability expression is:

P(B|C) = n(B and C)/n(C)

Substitute known values

P(B|C) = 9/24

Evaluate the expression

P(B|C) = 0.38

Hence, the value of P(B|C) is 0.38

Answer:

y = -1/2 x + 10.

Step-by-step explanation:

The line q has the same slope (-1/2) as line p as the 2 lines are parallel.

Equation of the line q:

y - 8 = -1/2(x - 4)

y - 8  = -1/2x + 2

y = -1/2 x + 2 + 8

y = -1/2 x + 10.

An expression is formed of numbers, variables, and mathematical operations. The expression that is equivalent to 35m²-63 is 7(5m²-9).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given the expression 35m²-63, which can be written as,

[tex]35m^2-63\\[/tex]

Answer:

20 seconds

Step-by-step explanation:

1ft in 10 seconds = 12 in / 10 sec

to get 24 inches, or 2 feet, we simply multiply that by 2:

(12 in /10 sec) * 2

24 in /20 sec

Answer:

20 seconds!

Step-by-step explanation:

A foot is equal to 12 inches meaning you take 12 and divide it by 24 to get 2 meaning its 2 feet. and if it took 10 seconds for one foot, then it will take 20 seconds for 2 feet

Answer:

  B.  (x, y) ⇒ (x, -y)

Step-by-step explanation:

When a point is reflected over the x-axis, it is moved along a vertical line to the same distance on the other side of the x-axis.

The x-coordinate of a point identifies its distance from the y-axis--the vertical line it is on. The y-coordinate identifies its distance from the x-axis. Changing the sign of the y-coordinate moves the point to the same distance on the other side of the x-axis--reflecting it over the x-axis.

__

The given points ABC and A'B'C' all match the pattern ...

  (x, y) ⇒ (x, -y)

  A(-1, 7) ⇒ A'(-1, -7)

  B(6, 5) ⇒ B'(6, -5)

  C(-2, 2) ⇒ C'(-2, -2)

so the image points represent a reflection over the x-axis of the original points.
