Solve for the indicated variable y=5x-6(x)

Answer:

x = +/-10°

Step-by-step explanation:

[2(x+10)]°=

[2x + 20] =

[2x] = [-20]

2x/2 = -20/2

x = -10

(3x - 30)°

3x/3 = 30/3

x = 10

Answer:

The value of x = 50°

Step-by-step explanation:

As,

[2(x+10)]°  &  (3x-30)° both are Vertically opposite angles.

we know,

vertically opposite angles are equal .

so,

2(x+10) = 3x-30

⇒2x+20 = 3x-30

⇒3x-2x=20+30

∴x=50

∴The value of x = 50°

Answer:

B) 120

Step-by-step explanation:

m = miles

$98=$80+$0.15m

$98-$80=$80-$80+$0.15m

$18=$0.15m

$18/$0.15=$0.15m/$0.15

120=m

Juliet drove 120 miles for $98.

(this is a good explanation, I guess)

Answer:

Option B) 120 miles

Step-by-step explanation:

Company charges per day for a car rent = $80

and per mile driven = $0.15

Juliet rented a car for one day and she was charged a total = $98

Let Juliet traveled x miles

$80 + $0.15x = $98

0.15x = 98 - 80

0.15x = 18

x = [tex]\frac{18}{0.15}[/tex]

x = 120 miles

Juliet was charged for 120 miles driving.

3x + 1 = 8

move +1 to the other side

sign changes from +1 to -1

3x+1-1= 8-1

3x= 7-1

divide by 3 for both sides to get x by itself

3x/3= 7/3

Answer:

x= 7/3 and x= 2 1/3

Answer:

[tex]\large\boxed{x=\dfrac{7}{3}=2\dfrac{1}{3}}[/tex]

Step-by-step explanation:

[tex]3x+1=8\qquad\text{subtract 1 from both sides}\\\\3x+1-1=8-1\\\\3x=7\qquad\text{divide both sides by 3}\\\\\dfrac{3x}{3}=\dfrac{7}{3}\\\\x=\dfrac{7}{3}[/tex]

Answer:

12

Step-by-step explanation:

(x-1)+(y+1)+(z-1)

= x -1 + y + 1 + z - 1

= x + y + z -1

= (x + y + z) -1

given that x+y+z = 13, substitute this value into the equation aove

(x + y + z) -1

= 13 - 1

= 12

Answer:

x=0

Step-by-step explanation:

A number is rational if it is the result of a fraction.

Take any number, if you can write it down as a fraction, then that number is rational.

Example: 2,5 is rational because it's 5/2.

A number is irrational if it's real and IS NOT rational.

Example: pi is irrational, e is irrational and also

[tex] \sqrt{72} [/tex]

A detailed explanation of whether [tex]\sqrt{72}[/tex] is rational or irrational, with examples and definitions to support the answer.

To determine whether [tex]\sqrt{72}[/tex] is rational or irrational, let's first simplify the expression:

[tex]\sqrt{72}[/tex] = [tex]\sqrt{36*2}[/tex]

[tex]\sqrt{72} = \sqrt{36}[/tex] × [tex]\sqrt{2}[/tex]

[tex]\sqrt{72[/tex] = [tex]6\sqrt{2}[/tex]

Now, 2 is an irrational number, as it cannot be expressed as a fraction of two integers where the denominator is not zero. Since [tex]\sqrt{2}[/tex] is irrational and [tex]\sqrt{6}[/tex] is rational, the product [tex]6\sqrt{2}[/tex] is also irrational.

Therefore, [tex]\sqrt{72}[/tex] is irrational.

D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin

Step-by-step explanation:

Well, the first obvious step is to reflect it across the y-axis. Now, for the next step, since we do not have a 90°-clockwise rotation option, we have to go with something similar to that, which would be a 270°-counterclockwise rotation. If you think about it, since 3 × 90 is 270, and rotating this figure 90° clockwise [one rotation] would go from Quadrant III to Quadrant II, going the other way around [270°counterclockwise (three rotations)] will also go from Quadrant III to Quadrant II [to Quadrant IIII to Quadrant I to Quadrant II].

Answer: 2/3

Step-by-step explanation: To find how much of the candy bar they each have, we will have to add the fractions. To add unlike fractions such as 1/3 and 4/12, we first need to find a common denominator. The common denominator of 3 and 12 is simply the least common multiple of 3 and 12 which is 12. To get 12 in the denominator of 1/3, we multiply the numerator and denominator by 4 to get 4/12. Notice that our second fraction already has 12 in the denominator so we can now add these fractions.

[tex]\frac{4}{12}[/tex] + [tex]\frac{4}{12}[/tex] = [tex]\frac{8}{12}[/tex].

Notice that 8/12 can be reduced by dividing both the numerator and denominator by 4.

8 ÷ 4 = 2

12 ÷ 4 = 3

Answer:

The number is 1 or -0.94 ( to the nearest hundredth).

Step-by-step explanation:

Let the number be x, then:

(4x)^2 = x + 15

16x^2 - x - 15 = 0

x = [-(-1) +/- sqrt(1 - 4 * 16 * -15)] / 32

x = 32/32 = 1 or

x = -0.94.

Answer:

 x=1           or      x = - [tex]\frac{15}{16}[/tex]

Step-by-step explanation:

To solve this problem, we will follow the steps below;

First, we need to re-write the question in a mathematical format.

Let x be the number

"The square of the product of 4 and a number is the sum of the number and 15"  can be written mathematically as;

(4x)²  = x + 15

16x² = x + 15

This equation can be re-written as;

16x² - x - 15 = 0

This is a quadratic equation, we can solve by formula method

x = -b ±√b² - 4ac   /2a

From the equation above,   a = 16      b = -1     and      c= -15

We can now proceed to insert the values into the equation

x = -b ±√b² - 4ac    /2a

x = -(-1) ±√(-1)² - 4(16)(-15)    /2(16)

x = 1 ±√1 + 960    /32

x = 1 ±√961   /32

x = 1 ± 31   /32

Either   x =  [tex]\frac{1+ 31}{32}[/tex]      or      x = [tex]\frac{1-31}{32}[/tex]

           x   = [tex]\frac{32}{32}[/tex]        or         x =[tex]\frac{-30}{32}[/tex]

we need to increase 150,000 by 4%. That means the value would be 150,000 multiplied by 1.04. So:

150,000 * 1.04 = 156,000

After 2nd year:

The new appreciated value of 156,000 will now suffer a loss of  6%. So we need to find the new value by multiplying 156,000 by 0.94 (6% loss). So:

156,000 * 0.94 = 146,640
