SOLVE FOR x:3+2(8x-1)=5+4(4x-6)
I'm giving you brainliest if your right

Answer:

So the slope is rise over run. You need the y intercept and the slope to write an equation. To find the y intercept, use the formula : 0=4(slope)*3+b and you get 0=12+b then you subtract twelve from both sides, getting b=-12. Thats your y intercept. So your equation will be y=4x-12

Answer:

X=2y+1

X-1/2=y

Answer:

j = 6

Step-by-step explanation:

1. What one needs to know

-Slope-intercept form

The formula of a line in slope-intercept form is;

y = mx + b

Where "m" is the slope. and "b" is the y-intercept.

2. Approach

The slope of the line is given. One has to solve for the y-intercept. Since a point on the line is given, one simply has to substitute in the point on the line and solve for b. The one substitutes in the other point with the unknown in it. One will then solve to find the unknown.

3. Finding "b"

It is given that this line has a slope of [tex]\frac{1}{5}[/tex], therefore, the equation of the line with the slope would look something like this;

y = [tex]\frac{1}{5}[/tex]x  + b

It is given that (-4, -8) is on the line, substitute this point in;

-8 = [tex]\frac{1}{5}[/tex](-4) + b

Solve;

-8 = [tex]\frac{1}{5}[/tex](-4) + b

-8 = - 0.8 + b

-7.2 = b

The complete formula of this line is;

y = 0.2(x) - 7.2

( in decimals )

4. Solve of "j"

Point (j, -6) is on this line, substitute it into the formula

y = 0.2(x) - 7.2

-6 = 0.2(j) - 7.2

Inverse operations;

-6 = 0.2(j) - 7.2

+7.2          +7.2

1.2 = 0.2(j)

/0.2   /0.2

6 = j

Answer:

length = 14.14 m and width=width 11.32 m

Step-by-step explanation:

length be L and width be w

L:w = 5:4

L/w = 5/4

Let L =5k and w=4k

since A= lengthxwidth

A=5k x 4k

so, 160 = 20 k2

k 2 = 8

k = 2.828

since L = 5k in above, L= 5x2.828= 14.14

and since w=4k in above, w=4x2.828 = 11.32

This is my Guess. ..

Answer:

I hope it will help u

Step-by-step explanation:

As given that

L:W=5:4

L/W=5/4

hence we also know that

As given A=160m2

putt the value of A and L=(5/4)W in above equation ,

hence      160 = (5/4)W * W

W^2 = 160*4/5

W^2 = 32*4

W^2=128

taking square root

W= +_ 11.3

but length can't be negative so we take positive value of W

Answer:

slope = - [tex]\frac{3}{11}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 5, 7) and (x₂, y₂ ) = (6, 4)

m = [tex]\frac{4-7}{6+5}[/tex] = [tex]\frac{-3}{11}[/tex] = - [tex]\frac{3}{11}[/tex]

Answer:

if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR

We conclude that  'Symmetric Property of Angle Congruence' illustrates this statement.

Step-by-step explanation:

We know that the Symmetric Property of Angle Congruence can be defined as

For example, Let suppose

As ∠X≅∠Y i.e. 20 ≅ 20

then

∠Y≅∠X i.e. 20 ≅ 20

Given

if ∠PQR ≅ ∠STU, then ∠STU ≅ ∠PQR

Thus, we conclude from the above discussion that 'Symmetric Property of Angle Congruence' illustrates this statement.

Step-by-step explanation:

The total amount of money saved will be 50 - 16c

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given are 4 friends who are buying tickets for a concert. The cost to buy one ticket is c dollars. If you buy all the tickets together, there is a discount and the cost is (5c - 12.5) dollars.

When buyed separately, the total cost = $4c

When bought together, the total cost = $4(5c - 12.5)

Money saved = 4c - 4(5c - 12.5) = 4c - 20c + 50 = 50 - 16c

Therefore, the total amount of money saved will be 50 - 16c

Answer 2  2/19

there is you answer

Answer:   -19+27

Step-by-step explanation:

Answer:

cost of crab meals = $20

cost of vegetarian meals = $38

Step-by-step explanation:

Let

x = cost of crab meals

y = cost of vegetarian meals

Troop A

12 crab meals and 23 vegetarian meals, with total receipts of $916.

12x + 23y = 916

Troop B

12 crab meals and 12 vegetarian meals, bringing in a total of $696

12x + 12y = 696

12x + 23y = 916 (1)

12x + 12y = 696 (2)

Subtract (2) from (1)

23y - 12y = 916 - 696

11y = 220

y = 220/11

= 20

y = 20

Substitute y = 20 into (1)

12x + 23y = 916

12x + 23(20) = 916

12x + 460 = 916

12x = 916 - 460

12x = 456

x = 456/12

= 38

x = 38

cost of crab meals = $20

cost of vegetarian meals = $38

Answer:102 children and 337 adults swam at the publice pool that da

Step-by-step explanation:

let the number of children be x

and

the number of adults be y

such that the total number of people who came to use the public swimming pool be expressed as

x + y = 439----- Equation 1

and price  for swimming be expressed as

1.75x + 2.50y =1021----- Equation 2

Step 2

x + y = 439----- Equation 1

1.75x + 2.50y =1021----- Equation 2

First make x the subject formulae and put in equation 2

x= 439-y

1.75 (430-y) + 2.50y = 1021

Solving gives

768.25-1.75y+2.50y=1021

2.50y-1.75y=1021-768.25

0.75y=252.75

y =252.75/0.75  

y=337

To find x, put the value of y = 337 in equation 1

x+y= 439

x= 439-337

x=102

Therefore 102 children and 337 adults swam at the public pool that day

Answer:

9:1, 18:2, 27:3, 36:4, 45:5 or 1,2,3,4,5

Step-by-step explanation:

This is the answer because:

1) We can see that eah ratio is being multiplied with the next number. We can say this because 9 x 2 = 18 and 1 x 2 = 2 which is 18:2 just like that 9 x 3 = 27 and 1 x 3 = 3 which makes the ratio 27:3.

2) If we keep on doing this, 9 x 4 = 36 and 1 x 4 = 4 which makes the ratio 36:4.

Therefore, the answer is 4.

Answer: The percent of the people surveyed were satisfied with the car = 40% .

Step-by-step explanation:

Given: Total number of people surveyed = 3300

Number of people said that they would buy that type of car again = 1320

i.e. Number of people were satisfied with the car = 1320

The percent of the people surveyed were satisfied with the car =

[tex]=\dfrac{1320}{3300}\times100\\\\=\dfrac{12}{30}\times100\\\\=\dfrac{4}{10}\times100\\\\=0.4\times100=40\%[/tex]

Hence, the percent of the people surveyed were satisfied with the car = 40% .

Answer:

8.4 kg

Step-by-step explanation:

First, find how much waste is created in a week:

Multiply 2 by 7, since they create 2 kg of waste each day:

2(7)

= 14 kg

Then, find 60% of this:

Multiply 14 by 0.6:

14(0.6)

= 8.4

So, the amount of compostable waste created by 1 person in a week is approximately 8.4 kg

The amount of compostable waste that could be generated by one individual in a week would be closest to 8.4kg.

Using this formula
Compostable waste amount=Kg of waste× Number of days in a week× Municipal solid waste percentage

Where:
Kg of waste=2kg

Number of days in a week=7 days

Municipal solid waste percentage=60% or 0.60

Let plug in the formula

Compostable waste amount=2kg×7 days×0.60

Compostable waste amount=8.4 kg

Inconclusion the amount of compostable waste that could be generated by one individual in a week would be closest to 8.4kg.

Answer:

Step-by-step explanation:

Alright, after reading this problem, let’s highlight some key points. Each sweater costs $25, we can write that down as 25x because will represent the amount of sweaters we buy. But we have a shipping fee of $7, so we will +7 to our highlights. And the total money spent was $132.

So far, we have: 25x + 7 = 132

Let’s subtract the 7 from the 132. Now we have: 25x = 125

Then we can divide by 25 on each side, and get x by itself.

X = 5 sweaters.

BONUS: Let’s replace 5 for our x to prove our answer

25(5) + 7 = 132 >>> 125 + 7 = 132 >>> 132 = 132 :D

Answer:

141 coins

Step-by-step explanation:

Given that Mark has a total of 380 coins(assumed to be shared amongst Albert,Casey, Lily and Logan)

Albert= x

Casey= 2x

Lily= 2x+5

Logan=3x

There's a total of 380 coins

x+2x+2x+5+3x= 380

8x+5=380

8x=380-5

x=375/8

x= 46.9

Therefore Logan's coins = 3x= 3×46.9= 140.61 coins

Approximately Logan's coins =141 coins
