$48
30 divided by 5 is 6. Multiply that by 3(3/8) to get 18
18+30=48

The answer is that she had 48.  Set it up as an equation with x as the amount of money she started with.  x - 30 = 3/8x.  That says, in words, "the amount of money she started with minus 30 for the dress left her with 3/8 of the money she started with.  Solve for x by adding 30 to both sides and subtracting 3/8 from 8/8x (8/8 = 1).  8/8 - 3/8 = 5/8, so 5/8x = 30, multiply both sides by 8 to get 5x=240 and x = 48.

A b c or d please hurry thanks!
otez555 [7]

Answer:

C)  a = 10√3, b = 5√3, c = 15 , d = 5

Step-by-step explanation:

Here we use the ratio of 30, 60, 90 degree triangle.

The ratio of sides, 1:√3:2

2x = 10

x = 5

d = 5

b = 5√3

c = 5√3√3

c = 5*3 = 15

c = 15

a = 2(5√3)

a = 10√3

Therefore, a = 10√3, b = 5√3, c = 15 and d = 5

Thank you.

Solve the equation for all values of x in simplest form (x + 3)^2 = -16
Arlecino [84]

Answer:

x = -7 or  x = 1

Step-by-step explanation:

Given expression:

    (x + 3)²  = -16

 

Problem;

   Solve for x;

Solution:

 To solve for x; we use the factorization method;

     Take -16 to the left of the equation;

      (x + 3)²  = -16

         (x + 3)² + 16 = 0

       (x+ 3)² + 4²  = 0

if    x² + y²  = (x + y)(x - y)

     So;

       (x + 3 + 4) (x + 3 - 4) = 0

       (x + 7)(x - 1) = 0

       x + 7  = 0 or x - 1 = 0

      x = -7 or  x = 1
