The following examples illustrate the inverse property of multiplication. Study the examples, then choose the statement that bes
Scilla [17]

Answer:

For all real numbers a except 0, we have

a(1/a) = 1

Step-by-step explanation:

Multiplication of real numbers are having the following properties:

i) commutative = ab = ba

ii) associative a(b+c) =ab+ac

iii) Multiplicative identity element exists such that for any number

a*1 =1*a = a

i.e. 1 is identity.

Inverse property is for any a not equal to 0, we have a real number such that

a*that real number = multiplicative identity

i,.e. a(a real number) = 1, a not equal to 0

In other words, there exists an 1/a for all a not equal to 0 satisfying a*1/a = 1

Help I need to get this done I have 15 questions
ivanzaharov [21]

Answer:

8 cm

Step-by-step explanation:

(See the image attached for details)

  • The blue segment measures 15 cm
  • The green segment measures 7 cm
  • The green and yellow segment when added form the blue segment
  • So: ? + 7 = 15

Solve:

? + 7 = 15

Subtract 7 on both sides:

? + 7 = 15

   -7     -7

? = 8 cm

Therefore, the yellow segment, or the missing side length, measures 8 cm.
