Answer:

k = 77

Step-by-step explanation:

k ÷ 11 = 7

Sally lends half her collection of formal attire to her sister Annie, sally then buys four more attires. If she had 12 attires n
BartSMP [9]

Answer:

16 attires

Step-by-step explanation:

Let us represent the number of attires:

Sally has initially = x

Sally lends half her collection of formal attire to her sister Annie

This means, Sally has currently = 1/2x attires

Sally then buys four more attires. If she had 12 attires now.

Hence, this is expressed Mathematically as:

1/2x + 4 = 12

1/2x = 12 - 4

1/2x = 8

x/2 = 8

Cross Multiply

x = 8 × 2

x = 16

Therefore, the amount of attires Sally had initially = 16 attires

What is the solution of √-4x=100?<br> A) x = –2500<br> B) x = –50<br> C) x = –2.5<br> D) no solution
yawa3891 [41]
First we raise both members of the equality to the square:
 (√-4x) ^ 2 = (100) ^ 2
 Then, we solve:
 -4x = 10000
 We cleared x in the last instance
 x = 10000 / (- 4)
 x = -2500
 answer:
 the solution of √-4x=100 is 
 A) x = –2500

Answer:106.38 feet

Step-by-step explanation:

This can be solved by using pythagoras theorem

 

c=110 feet

b=28 feet

a=?

a=sqrt(110^2-28^2)

=sqrt(12100-784)

=sqrt(11316)

=106.3766 feet

=106.38
