8. complementary angles = 90°
3x+3+10x-4 = 90
13x-1 = 90
13x = 91
so x = 91/13= 7
then K = 3(7)+3 = 24°
so L = 10(7)-4 = 70-4 = 66°

9. P is three less than twice of Q
so P = 2Q-3
supplementary angles = 180°

P+Q = 180
(2Q-3)+Q = 180
3Q-3 = 180
3Q = 183
so Q = 183/3 = 61°
then P= 2(61)-3 = 122-3 = 119°

10. B is two more than three times of C so B= 3C+2
complementary angles = 90°

B+C= 90
(3C+2)+C=90
4C+2=90
4C= 88
so C= 22°
then B = 3(22)+2= 66+2 = 68°

The sum of 4 times the number x and 26 is 130.
Lesechka [4]

Answer:

A. Correct choice is C

B. Correct choice is B

Step-by-step explanation:

4 times the number x is 4x.

The sum of 4 times the number x and 26 is 4x+26.

The sum of 4 times the number x and 26 is 130, then

4x+26=130.

Correct option is option C.

Solve this equation:

4x=130-26,

4x=104,

x=26.

Identify the equation of the circle that has its center at (16, 30) and passes through the origin
Veronika [31]

To solve this question, we have to find the equation of the circle with given center and where it passes. Doing this, we get that the equation of the circle is:

(x - 16)^2 + (y - 30)^2 = 1156

Equation of a circle:

The equation of a circle with center (x_0, y_0) and radius r is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

Center at (16, 30)

This means that x_0 = 16, y_0 = 30

Thus

(x - 16)^2 + (y - 30)^2 = r^2

Passes through the origin:

We use this to find the radius squared, as this means that x = 0, y = 0 is part of the circle. Thus

(x - 16)^2 + (y - 30)^2 = r^2

(0 - 16)^2 + (0 - 30)^2 = r^2

r^2 = 16^2 + 30^2 = 1156

Thus, the equation of the circle is:

(x - 16)^2 + (y - 30)^2 = 1156

Which of the following rational numbers is equal to 2 point 8 with bar over 8 ? twenty two over nine, twenty four over nine, twe
alina1380 [7]
Just to remove ambiguities, the bar over the expression means it's repeating itself to infinity.

\bf 2.888\overline{8}\impliedby \textit{now say, let's make }x=2.888\overline{8}&#10;\\\\\\&#10;\textit{and multiply it by 10, to move over the 8 to the left}&#10;\\\\\\&#10;\begin{array}{llll}&#10;10x&=&10\cdot 2.888\overline{8}\\&#10;&&28.88\overline{8}\\&#10;&&26+2.888\overline{8}\\&#10;&&26+x&#10;\end{array}\implies 10x=26+x&#10;\\\\\\&#10;9x=26\implies x=\cfrac{26}{9}

notice, the idea being, you multiply it by 10 at some power, so that you move the "recurring decimal" to the other side of the point, and then split it with a digit and "x".

now, you can plug that in your calculator, to check what you get.
