this is my second problem​

Answer:

68

Step-by-step explanation:

x + x = 136

2x = 136

x = 136 / 2

x = 68

Answer:

• This triangle is isosceles hence two angles are equal.

• But, the sum of two interior angles are equal to the exterior angle.

[tex]{ \rm{x + x = 136 \degree}} \\ \\ { \rm{2x = 136 \degree}} \\ \\ { \boxed{ \rm{ \: \: x = 68 \degree \: \: }}}[/tex]

Answer:

Slope = 0

Step-by-step explanation:

Equation: y = 5

Since the graph would show a horizontal line (passing through 5) the slope would be zero

Answer:

∠p, ∠q, and ∠r are all 40°

Step-by-step explanation:

ARQ is a triangle so the sum of the interior angles must equal 180°

48 + 52 = 100

180 - 100 = 80°

This means that the last angle, 2p = 80°

If 2p = 80, then ∠p = 40° (divide by 2)

PQR is also a triangle which means PR is a straight line

The angle next to 2p is going to be 100, because 2p was 80 and angles on a straight line add to 180° (180 - 80 = 100)

∠r = ∠p because they are alternate angles (in the sideways Z shape), 40°

∠q can be found by doing:

180 - (∠PAQ + ∠r)

= 180 - (100 + 40)

= 180 - 140

= 40

Answer:

Step-by-step explanation:

From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.

The area of the circular sector is the space occupied by it. The area of the circular sector is the half of the product of the angle of the sector and the radius of the circle. It can be given as,

[tex]A_s=\dfrac{r^2\theta}{2}[/tex]

Here, (r) is the radius of the circle and θ is the angle of the sector. Multiply with π/180 to convert it into the degrees.

[tex]A_s=\dfrac{r^2\theta}{2}\left(\dfrac{\pi}{180}\right)\\A_s={\pi r^2}\left(\dfrac{\theta}{360}\right)[/tex]

Thus, the option D is correct. Now, πr² is the area of circle . Thus,

[tex]\rm \text{Area of sector}=\dfrac{(Area\; of \;Circle)(Arc\; Measure)}{360^o}\\\rm \dfrac{(Area\; of \;Sector)}{(Arc\; Measure)}=\dfrac{\text{Area of sector}}{360^o}[/tex]

From the following, which is NOT an equivalent expression to Area of sector is 2πrθ/360. Option A is correct.

May be wrong though

Answer:

y = -5/7(x) - 3/7

Step-by-step explanation:

1. We're already given the value of m in y = mx + b: -5/7. So, our equation looks like this so far: y = -5/7(x) + b.

2. To solve for b, the y-intercept, we use this formula: [tex]b = y_1 - m * x_1[/tex]

3. Now that we know the values of m and b, the equation looks like this: [tex]y = -\frac{5}{7}x -\frac{3}{7}[/tex].

Therefore, the answer is [tex]y = -\frac{5}{7}x -\frac{3}{7}[/tex].

Answer:

A = S square (s^2)

we know that A = 1296 square inches, then,

[tex]\sqrt{1296} = \sqrt{s^{2}} \\[/tex]      we square both sides and cancel out the square on the right                side. We get:

36 = s

The length of the sign is 36 inches.

Answer:

f(x) = 7/6

Step-by-step explanation:

First off, hello! This is my explanation to the provided answer,

You can use the slope formula, (or simply graph the points), y2 - y2 / x2 - x1.

This would give you: 1 - 8 / -2 - 4, meaning that you would get the answer: 7/6 as the slope.

Hope this helps, if you have any more questions please ask.

The equation of a line passing through the points (2, 3) and (4, 6) is 3x - 2y = 0.

Step-by-step explanation:

Answer

If Christina's age is = x

Aaron's age is = x + 6

Jeo's age = 3(x + 6 )

So, the sum of their ages can be write as,

[tex]x + x + 6 + 3(x + 6) \\ x + x + 6 + 3x + 18 \\ 5x + 24[/tex]

Also, they have given that the sum of their ages is 149

Therefore we can write a equation as,

[tex]5x + 24 = 149[/tex]

Now let's solve this and find the age of Christina

[tex]5x + 24 = 149 \\ 5x = 149 - 24 \\ 5x =12 5 \\ \frac{5x}{5} = \frac{125}{5} \\ x = 25[/tex]

Aaron's age is

[tex] x+ 6 \\ 25 + 6 \\ = 31[/tex]

Joe's age is

[tex]3(x + 6) \\ 3(25 + 6) \\ 3 \times 31 \\ = 93[/tex]

Hope this helps you.

Answer:

68.50 in

Step-by-step explanation:

first we are given the width and the length for the rectangle and so we know that 4 × 5x + 7 = 128

so we would now solve for x:

4 × 5x + 7 = 128

= 4 × 5x = 121

= 20x = 121

= x = 6.05

now we can plug in 6.05 for x and find the perimeter:

5(6.05) + 4 = 34.25

5(6.05) + 4 = 34.25

34.25 + 34.25 = 68.50

Answer:

y = 5x + 8

m = 5

Step-by-step explanation:

ok so perpendicular means negative reciprocal of the slope so the original slope of the line is -1/5x so the negative reciprocal is 5 (5/1 and the negative undos the negative so it's positive) so now we will use the point (-2, -2) and plug that into the slope intercept form (y = mx+b)

so -2 = 5(-2) + b

5 • -2 = -10 and u add that to the other side so b = 8 so the answer is y = 5x + 8! hope this helps!

Answer: (x+1)(3x+2) , i only got the answer for the first question, sorry!

Step-by-step explanation:

- factorise using AC method

AC= 3 x 2 = 6

find 2 numbers that add to give 5 and multiply to give 6 (3 and 2)

- put them as x in the equation to replace 5x

3x^2 + 2x + 3x + 2

- split the equation in half and expand each side

3x^2+2x | 3x+2

x(3x+2)+1(3x+2)

- put the numbers outside the brackets into a separate bracket

= (x+1)(3x+2)

Answer:

[tex]a^{2} -1[/tex]

Step-by-step explanation:

The LCD, or the lowest common denominator would be [tex]a^2-1[/tex]

If we multiply the second term [tex]\frac{1}{a+1}[/tex] by [tex]\frac{a-1}{a-1}[/tex] ([tex]\frac{a-1}{a-1}[/tex] is equivalent to 1, so we can do this,) we can see that the denominator would become the same as the first term [tex]\frac{1}{a^2-1}[/tex] by difference of squares. So that creates an LCD of [tex]a^2-1[/tex]
