X-18 = 2 (X-25)
x-18 = 2x - 50
-18 = x - 50
32 = x

check
32-18 = 14 = 2(32-25) = 2*7

Answer:

$32

Step-by-step explanation:

Both Lily and Sarh began with the same amount of money, represented by the variable (x).

Lily spends (take a away from her money) $18

L = x - 18

Sara spends (take a away from her money) $25

S = x - 25

Next: Lily as 2 times the amount of money Sara has after they each spend their money.

L = 2S

x - 18 = 2 ( x - 25 )

x - 18 = 2x - 50

(x - 18) + 50 = (2x - 50) + 50

cancels out 50 by adding to each side

x + 32 = 2x

(x + 32) - x = (2x) - x

cancels out x by subtracting from each side

32 = x

CHECK:

L = X - 18

L = 32 - 18 = 14

S = X - 25

S = 32 - 25 = 7

L = 2S

14 = 2 (7)

Multiplying two complex numbers involves ______.
Alenkasestr [34]

Answer:

Multiplying a complex number by a real number

(x + yi) u = xu + yu i. In other words, you just multiply both parts of the complex number by the real number. For example, 2 times 3 + i is just 6 + 2i. Geometrically, when you double a complex number, just double the distance from the origin, 0.

binomial methods

Complex numbers use binomial methods of multiplication because unlike real numbers, imaginary numbers have two components.

So probably A. I sorry, but I need more information. Hope this helps

If the measure of angle ABF=6x+26 and the measure of angle EBF=2x9 and measure of angle ABE= 11x-31 find the measure of angle AB
Hunter-Best [27]

Its not clearly given that whether EBF = 2x + 9 or 2x - 9.

I have written the solution for both.

If EBF = 2x + 9,

then ABF = 6x + 26 and ABE = 11x - 31.

Now, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x + 9)

           = (6x + 2x) + (26 + 9)

           = 8x + 35

11x - 8x = 35 + 31

3x = 66

x = 22

Therefore, ABF = 6x + 26 = 6(22) + 26 = 132 + 26 = 158°

If EBF = 2x - 9,

then ABF = 6x + 26 and ABE = 11x - 31.

Now, ABE = ABF + EBF

11x - 31 = (6x + 26) + (2x - 9)

           = (6x + 2x) + (26 - 9)

           = 8x + 17

11x - 8x = 17 + 31

3x = 48

x = 16

Therefore, ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°

factor the trinomial completely:
2x</span>² + x - 15 = 0
2x² + 6x - 5x - 15 = 0
2x(x + 3) - 5(x + 3) = 0

<span>use the zero product property and set each factor equal to zero and solve:
2x - 5 = 0     or     x + 3 = 0
