The value of x according to the secant-secant theorem is 4

<h3>Secant-secant theorem</h3>

Secant-secant theorem states if two secants are drawn from an external point to a circle, then the product of the measures of one secant's external part and that entire secant is equal to the product of the measures of the other secant's external part and that entire secant.

Using the equation below;

6(x+6) = 5(5+x+3))

Expand the expression
6x+36 = 5(x+8)

6x + 36 = 5x + 40

Subtract 5x from both sides

6x-5x +36 = 40

Subtract 36 from both sides

6x - 5x = 40 - 36

x = 4

Hence the value of x according to the secant-secant theorem is 4

A bride and groom both invited guests to their wedding. The bride invited twice as many women as the groom did, and the groom in

n200080 [17]

Answer:

option 1) 50

Step-by-step explanation:

Let m and w denote the men and women respectively.

From the question, if the groom invited w number of women, then bride invited 2w number of women.

Also, if the bride invited m number of men,then the groom invited 2m.

Hence we can write the following maths equation:

w+2m=105.........1

2w+m=135.........2

We multiply eqn(1) by 2 to get eqn(3)

This implies that,

2w+4m=210.......3

We then subtract eqn (2) from eqn(3) to obtain;

3m=75

we divide through by 3

$\implies \frac{3m}{3} = 75$

$\implies m= 25$

Substituting the value of m into eqn (1)

to find the value for w

$\implies w + 50 = 105$

subtracting 50 from both sides.

$\implies w + 50 - 50= 105 - 50$

$\implies w+2(25)=105$

$\implies w= 55$

So we can say the :

bride invited 25 men and 110 women,

groom invited 50 men and 55 women.

1 ) V = 1/3 * 18² * 3.14 * 6 = 2,034.72 mm³
2 ) V = 1/3 * 6² * 3.14 * 9 = 339.12 in³
3 ) V = 1/3 * 150² * 3.14 * 240 = 5,652,000 in³

Elvira’s cafeteria has cartons of milk that are typical of school lunch. The milk supplier charges $0.35 per carton of milk, in

FromTheMoon [43]

Write the equation out: (total cost: 0.35C[per carton] + 75[delivery charge]) ≤ 500. Subtract 75 on both sides and it would be: 0.35C ≤ 425. Divide 0.35 on both sides and you'll get C ≤ 1214. Therefore, the maximum # of cartons that Elvira can buy is 1214 cartons of milk.
