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
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
One temperature colder that -7.2 F would be -9 F.
-9 < -7.2
The -9 would be 1.8 units to the left of -7.2 on the number line.

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
