Answer:

Step-by-step explanation:

Δ DCA and Δ ABE are similar, thus the ratios of corresponding sides are equal, that is

$\frac{CA}{BE}$ = $\frac{DA}{AE}$ , substitute values

$\frac{18}{10}$ = $\frac{x+8}{8}$ ( cross- multiply )

10(x + 8) = 144 ( divide both sides by 10 )

x + 8 = 14.4 ( subtract 8 from both sides )

x = 6.4 → D

Paha777 [63]

In order to see the probaability of this we need to do an easy calculation here:
If X is the price for the policy, then we proceed like this:

0.982x = 0.0275*31,000

x = 0.0275*31,000/0.982

HELP ASAP What is the solution to the system of equations? y = x + 3 y = -x-1

ASHA 777 [7]

Answer:

(A) Is right

Step-by-step explanation:

$y = x + 3 \\ y = - x - 1 \\ substitute \: y = - x - 1 \: in \: above \: eq \\ weget \\ - x - 1 = x + 3 \\ 2x = - 4\\ x = - 2 \\ \\$

put X= -2. in y = X+3

to get y 's value

Y = -2+3

= 1

therefore, your solution is ( -2,1)
