d = b - 3 / 10

Step-by-step explanation:

b = 10d + 3

  • Place +3 in the other side of the equal sign
  • + 3 becomes - 3
  • b - 3 = 10
  • Divide both sides by 10 to make d the subject
  • b - 3 / 10 = 10d / 10
  • d = b - 3 / 10

Answer: A

3. sqrt(25) = 5

sqrt(b^2) = b

a must be left alone.  There's only 1 of them.

Annie walks 15 feet away from her house and places a mirror on the ground. She backs 4 feet away from the mirror so that she can
artcher [175]

Answer:

The house is 18.75 feet tall

Step-by-step explanation:

The triangles are similar by the AA postulate.  

We are given the length of the bottom sides of the triangles, 4 and 15 respectively.  

Thus, the ratio is 4:15

We are also given the height of Annie's eyes, which is 5 feet. The height of the side that corresponds to the house is 5, so we can set up a proportion.

\frac{4}{15}  = \frac{5}{x} \\4x = (5*15) = 75\\x = \frac{74}{4} \\x = 18.75

Thus, the house is 18.75 feet tall.
