Answer:

x = 37 / 7

Step-by-step explanation:

the angles shown here are pair of alternate interior angles .

which are equal,

so,

=》12x - 18 = 5x + 19

=》12x - 5x = 19 + 18

=》7x = 37

=》x = 37 / 7

Pls solve this for me

Georgia [21]

Answer: 253.5

Step-by-step explanation:

If your equation is 6s^2, all your doing is:

6x6.5^2,

or the long-form

(6.5*6.5) + (6.5*6.5) + (6.5*6.5) + (6.5*6.5) + (6.5*6.5) + (6.5*6.5) = 253.5

What is the equation of the circle with center (0, 0) that passes through the point (5, -4)?

Katyanochek1 [597]

The standard form of a circle is $(x-h) ^{2} +(y-k) ^{2} = r^{2}$ where h and k are the center and x and y are the coordinates you're given. We need to solve for the radius to finish this off correctly. Filling in, we have $(5-0) ^{2} +(-4-0) ^{2} = r^{2}$ and $25+16= r^{2}$ , giving us that $r^{2}=41$ . Therefore, our equation is $x^{2} + y^{2} =41$

The table shows the ratio of caramel corn to cheddar corn in a bag. What is the constant of proportionality?

Anit [1.1K]

For proportionality constant problems, set up the equation as,

$x=Ky$ ,

Where x and y are the two variables you are comparing and K is the proportionality constant. If we take Caramel Corn values as x and Cheddar Corn values as y, and then solve for K for each ratio lines, we will get the same answer. Let's check.

$15=K(10)\\K=\frac{15}{10}= \frac{3}{2}$ ,

$30=K(20)\\K=\frac{30}{20}= \frac{3}{2}$ , and

$45=K(30)\\K=\frac{45}{30}= \frac{3}{2}$ .

Hence, the proportionality constant, in this case K, is equal to $\frac{3}{2}$ or 1.5. First answer choice is correct.
