Find AC,AB=9x+1 BC=6x+25

Answer:

63 %

Step-by-step explanation:

Percentage change in value value for any number is given by

percentage change = (new value - old value) /old value * 100

we can also write it as

percentage change = (change in value ) /old value * 100

cost of commercial in 1968 = $54000

cost of commercial in 1973 = $88000

change in cost of commercial = cost of commercial in 1973 - cost of commercial in 1973  = $(88000-54000) = $34000

thus,

percentage change in cost of commercial

         = change in cost of commercial/cost of commercial in 1968 * 100

         = 34000/54000*100 = 62.96 %

Thus, percentage change in cost of commercial is 62.96 %

we have to round it to nearest whole number

rounded value of 62.96 is 63

in that case

percentage change in cost of commercial is 63 %

Answer:

Step-by-step explanation:

Answer:

4F-1

Theres infinite amount of solutions

Step-by-step explanation:

12f/3=4f

-3/3=-1

4f-1=4f-1

Answer:

f = 0

Step-by-step explanation:

[tex] \frac{1}{3} (12f - 3) = 4f - 1[/tex]

Use ⅓ to open the bracket

[tex] \frac{1}{3} \times \: 12f = 4f \\ \frac{1}{3} \times 3= 1[/tex]

[tex]4f - 1= 4f - 1[/tex]

Collect like terms

[tex]4f - 4f = - 1+1 \\ - 1f = 0 \\ \\ f = 0[/tex]

Answer:

B) n=-2

Step-by-step explanation:

First, distribute.

7(1+4n)-5=-38+8n

7+28n-5=-38+8n

Combine like terms.

2+28n=-38+8n

To make solving the equation easier, subtract 8n first, so there isn't a negative variable.

2+28n=-38+8n

  -8n           -8n

2+20n=-38

Subtract 2 on both sides.

2+20n=-38

-2          -2

20n=-40

Divide by 20 on both sides.

20n=-40

/20   /20

n=-2

Hope this helps!! Have a wonderful day :3

Answer:

m = 10

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

150+25x= 55x

      -25x  -25x

150= 30x

150/30 = 30x/30

x = 5

Hope this helps!

Answer: x =5

Steps: 150 + 25x = 55x

Subtract 150 from both sides: 150 + 25x - 150 = 55x - 150

Simplify: 25x = 55x - 150

Subtract 55x from both sides: 25x - 55x = 55x - 150 - 55x

Simplify: -30x = -150

Divide both sides by -30:  -30x ÷ -30 = -150 ÷ -30

Simplify: x = 5

Plz mark brainliest:)

Answer:

X=17

Step-by-step explanation:

Im sorry if this sounds a bit confusing. Im better at doing the math then explaining it. All the angles in that are 90-degree angles and because of that, you can assume that the angle that you trying to find is also 90 degrees. So to find that equation you can do this.

4x+22=90 -22 from both sides.

-22=-22  

you are left with

4x=68 then divide 4 from both sides.

/4=/4

you then get x=17 which is your answer.

Check your answer by plugging 17 into x.

4*17+22=90

The answer is 90 so you are correct.

Answer:

From what i can see i believe it is similar

Step-by-step explanation:

(Let me know if you need me to be more descriptive)

Answer:

they are similar. the measures of the corresponding sides of two triangles are proportional. DE is proportional to NM, and EF is proportional to NP, both as a 2:1 ratio.

this is because when she moves front, she takes 1 step back, so 16/2=8

Answer:

-2=2

Step-by-step explanation:

Answer:

w = 3

Step-by-step explanation:

-5w + 3 = 4w - 6

were going to get the variable and the numbers on different sides

-5w + 3 - 3 = -5w

4w - 6 - 4w = -6

-5w + 4w = -1w or -w

-6 + 3 = -3

-w = -3

and since there're both negatives you can just take that away and you get

w = 3

Answer:

GCF(330, 75, 450, 225) = 15

Steps:

Prime factorization of the numbers:

330 = 2 × 3 × 5 × 11

75 = 3 × 5 × 5

450 = 2 × 3 × 3 × 5 × 5

225 = 3 × 3 × 5 × 5

GCF(330, 75, 450, 225)

= 3 × 5

= 15

The equation for that graph is f(x) = 3 sin 8x.  Nothing else is correct. THere is no horizontal shift (phase shift), nor is there vertical shift.  Just a period adjustment.

3 sin 8x

Answer:

  y ≤ [tex]\frac{1}{2} x + 2[/tex]

Step-by-step explanation:

≤ because the area below the line is shaded.

Answer:

x=8

Step-by-step explanation:

I think you mean find x, not m.

since angle DEG and angle GEF are a linear pair, they equal 180º.

18x-9 + 4x+13 = 180

22x + 4 = 180

subtract 4 from each side

22x = 176

divide each side by 22

x=8

Answer:

x > -25

d = liczba monet 10-centowych

p = liczba monet 5-centowych

Razem, Luca ma 40 monet:

d + p = 40

Jedna 10-centowa moneta ma wartość 10 centów, i jedna 5-centowa ma wartość 5 centów, więc

10d + 5p = 315

bo 3,15 euro = 315 centów.

Znajdź d i p :

(10d + 5p) - 5(d + p) = 315 - 5•40

5d = 115

d = 23

d + p = 40

23 + p = 40

p = 17

Answer:  17 would be the approximate value of x.

Step-by-step explanation: 4 is the √16, so the value plotted on the number line, 4.1 represents the square root of a slightly larger number than 16.

Answer:

y= 3x - 2

Step-by-step explanation:

The line passes through (0, -2). '-2' is the y-intercept.

The line passes through the points (2,4) and (1,1).

[tex]m=\frac{rise}{run}=\frac{1-4}{1-2}=\frac{-3}{-1}=3[/tex]

The equation should be y= 3x - 2.

Hope this helps.
