Jennifer is four less than three times Toby's age. If Jennifer is 23, then how old is Toby? equation: solution:​

you have to find the angles inside the triangle first so

- 180-109 = 71° (angles on a straight line add up to 180°)

- 55° (vertically opposite angles)

71+55= 126

180-126= 54

x=54°

Answer:

36/5 or 7 1/5 or 7.2

(These are all different forms of the same answer)

Method:

2 1/4 = 9/4

3 1/5 = 16/5

9/4 × 16/5 = 144/20

144/20 = 36/5

Answer:

50m

Step-by-step explanation:

550=length*11

length=550/11=50

Answer:

82°

Step-by-step explanation:

[tex] \triangle ABC\sim \triangle PQR... (given) [/tex]

[tex] \therefore m \angle Q = m \angle B... (cast) [/tex]

Therefore,

8x + 50 = 3x + 70

8x - 3x = 70 - 50

5x = 20

x = 20/5

x = 4

[tex] m \angle Q [/tex] = 8x + 50 = 8*4 + 50 = 32 + 50 = 82°

Step-by-step explanation:

Car 2 is traveling faster than Car 1. Option B is correct.

Given that,
The table and equation below show the proportional relationship between time, in seconds, x, and distance traveled, in feet, y, for two remote-control cars.

Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.

here,
Speed of the car 1,
= 85 - 75 / 17 - 15
= 10 / 2
= 5 feet/second

Speed of the car 2,
y = 10x
Where 10 is the speed of the car 2 feet per second.
So,
Speed of the car 2  is faster than car 1.

Thus,  Car 2 is traveling faster than Car 1. Option B is correct.

Answer:

x = 16, x = -7

Step-by-step explanation:

The question is;

35 * 4 = ( x - 7 ) ( x - 3 )

Combine like terms on one side;

140 = ( x - 7 ) ( x - 3 )

Distribute, remember to multiply every term with one another;

140 = [tex]x^{2}[/tex] - 3x - 7x + 21

Combine like terms;

140 = [tex]x^{2}[/tex] - 10x + 21

Inverse operations;

140 = [tex]x^{2}[/tex] - 10x + 21

-21                  -21

119 = [tex]x^{2}[/tex] - 10x

Factor;

119 = x ( x - 10 )

At this point it is fairly obvious that;

x = 16, x = -7

Note; One could have used a multitude of methods to solve this problem, one could have factored, completed the square, or used the quadratic formula, this method was simply chosen because it is easy to explain

Answer:g(x) = (x+3)/(x2-4)

The domain refers to all of the x values that the function can take on.  In a rational expression like the one above, we have to be careful that the denominator is never 0, since division by 0 is undefined.  We can factor the denominator of g(x) as follows:

g(x) = (x+3)/((x+2)(x-2)

The denominator will be zero when x = 2 or -2.  Otherwise, g(x) is defined on all other values of x.  So the domain of g(x) is "x = all x not equal to -2 or 2".  In interval notation, the domain is:

(-∞,-2)U(-2,2)U(2,+∞)

On a number line, draw it as follows:

-∞ <======o=====o=======> +∞

                   -2            2

Step-by-step explanation:

Answer:

640 tree frogs

Step-by-step explanation:

If 1 month = 4 weeks

3 months = 12 weeks (3x4)

After 2 weeks the frogs double to 20

After 4 weeks the frogs double to 40

6 weeks, it doubles to 80

8 weeks, it's 160

10 weeks it's 320

12 weeks, it's 640

Answer:

[tex]x =\± \frac{2\sqrt{6}}{7}[/tex]

Step-by-step explanation:

The question has missing details as the unit circle is not shown, However, I'll solve on a general terms.

Given

[tex]P = (x,-\frac{5}{7})[/tex]

Required

Determine the possible value of x

Since point p lies on the unit circle, we'll solve this question using the following unit circle formula:

[tex]x^2 + y^2 = 1[/tex]

Substitute -5/7 for y

[tex]x^2 + (-\frac{5}{7})^2 = 1[/tex]

[tex]x^2 + \frac{25}{49} = 1[/tex]

Collect Like Terms

[tex]x^2 =1- \frac{25}{49}[/tex]

Take LCM

[tex]x^2 =\frac{49 -25}{49}[/tex]

[tex]x^2 =\frac{24}{49}[/tex]

Take the square root of both sides

[tex]x =\± \sqrt{\frac{24}{49}}[/tex]

[tex]x = \±\frac{\sqrt{24}}{7}[/tex]

[tex]x = \±\frac{\sqrt{4*6}}{7}[/tex]

Split

[tex]x = \±\frac{\sqrt{4}*\sqrt{6}}{7}[/tex]

[tex]x =\± \frac{2*\sqrt{6}}{7}[/tex]

[tex]x =\± \frac{2\sqrt{6}}{7}[/tex]
