what's the value of x?​

Answer:

$11.02

Step-by-step explanation:

Im pretty sure this is right, srry if its not.

Answer:

Step-by-step explanation:

Remark 1

If you are using a mirror on the y axis, then only the x value is changed. The y value remains the same.

For (-6,2), -6 changes into plus 6

The new point is (6,2)

For (4,5), 4 changes to minus 4

The new point is (-4,5)

For (2,-1) the new point is (-2,-1)

Remark 2

But none of those are the answer you want. What you want is what happens to the y value? The answer is it remains the same. The y value is the range. So the answer goes from (-1 to 5) just as it did before.

(2x-1)=17

2x=17+1

x=18/2

x=9

Answer:

32

Step-by-step explanation:

since the question has an even number of age groups, we have to find the two middle numbers which are 30 and 34, add them together and then divide that answer by 2

30 + 34 = 64

64 ÷ 2 = 32

Answer:

i dont know if may answer is correct this is may answer 3

Answer:

The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age

Step-by-step explanation:

Let us solve the question

Assume that Erik is x years old

∵ Erik is x years old

∵ Erik is [tex]\frac{1}{3}[/tex] as old as Dawn

→ That means x = [tex]\frac{1}{3}[/tex] Dawn

∴ x = [tex]\frac{1}{3}[/tex] Dawn

→ Multiply both sides by 3

∴ 3x = Dawn

∴ Dawn is 3x years old

∵ Jiro is 4 years younger than Erik

→ That means Jiro = x - 4

∴ Jiro is (x - 4) years old

∵ Alita is 2 times as old as Jiro

→ That means Alita = 2 × (x - 4)

∴ Alita = 2 × (x - 4)

∴ Alita is 2(x - 4) years old

∵ The sum of all their ages is 72

→ That means add their ages and equate the sum by 72

∴ Erike's age + Dawn's age + Jiro's age + Alita's age = 72

∴ x + 3x + (x - 4) + 2(x - 4) = 72

The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age

Answer:

she will use about 28 cups of sugar

Step-by-step explanation:

14*2=28

part one of this would be x=6;

2x6 is 30

30+5 is 35

part two of this would be x=20;

20x4 is 80

80-7 is 73

Answer:

x = 15 and x = 20

Step-by-step explanation:

(2)

35 = 2x + 5 ( subtract 5 from both sides )

30 = 2x ( divide both sides by 2 )

15 = x

(3)

4x - 7 = 73 ( add 7 to both sides )

4x = 80 ( divide both sides by 4 )

x = 20

Answer:Number of minutes of second  Song = 5 1/4 minutes

Number of minutes of third   Song =3 1/2  minutes

Step-by-step explanation:

Number of minutes of First Song = 3 1/2 minutes

Number of minutes of second  Song = one 1/2 times as long as her first

= 1 1/2 X 3 1/2 minutes

3/2 X 7/2

21/4 = 5 1/4 minutes

Number of minutes of third   Song = 2/3 times as long as her second song

2/ 3 x 5 1/4

= 2/3 x 21/4 =42/12

Dividing the numerator and denominator by 3 to reduce the fraction

42/ 12 / 3/3 = 14/4

14/4 = 3 2/4 = 3 1/2  minutes

c because you multiply by pie which is 3.14 and that times 10 is 31.4

Answer:

C

Step-by-step explanation:

i think

Answer:

c. -3

Step-by-step explanation:

- 7x + 6= 27 [subtract 6 from both sides]

-7x = 21 [divide by -7 to isolate x]

x = -3

Answer:

The answer is C

Pay attention, here's why.

Step-by-step explanation:

Let's solve your equation.

−7x+6=27

Step 1: Subtract 6 from both sides.

−7x+6−6=27−6

−7x=21

Step 2: Divide both sides by -7.

−7x /−7 = 21/ −7

x=-3

Answer:

RIGHT

Step-by-step explanation:

Answer:

Step-by-step explanation:

The standard form of equation of a line in point slope form is expresses as

y - y0 = m(x-x0)

m is the slope

(x0, y0) is a point  on the line

Given

m = 1/3

(x0, y0) = (3, 5)

Substitute into the equation

y - 5 = 1/3 (x-3)

3(y-5) - x-3

3y - 15 = x-3

3y = x-3+15

3y = x+12

y = 1/2 x + 12/2

y = 1/3 x + 4

Hence the require equation of the line is y = 1/3 x + 4

  log₃(7) -2·log₃(5)

Step-by-step explanation:

The applicable rules of logarithms are ...

  log(a/b) = log(a) -log(b)

  log(a^b) = b·log(a)

You have ...

  [tex]\log_3\dfrac{7}{25}=\log_3{7}-\log_3{25}=\log_3{7}-\log_3{5^2}\\\\=\boxed{\log_3{7}-2\log_3{5}}[/tex]

Answer:

rectangle because the diagnals are congruent

Step-by-step explanation:

Answer:

71.764  feet

Step-by-step explanation:

See attached the rough sketch for your reference

Step one;

Given data

The angle of elevation= 25°

From the triangular diagram, we can see that the height of the church is the opposite, while the distance of the person from the church is the adjacent

Step two:

Applying SOH CAH TOA

tan∅= opp/adj

tan 25= opp/154

0.466= opp/154

cross multiply

0.466*154= opp

opp= height of church = 71.764  feet
