1. x/6>3 multiply both sides by 6
x>18
So a. and c. are both greater than 18
2.
-4x<32 divide both sides by -4 (and remember to reverse direction of inequality sign because of multiplication/division by a negative value!)
x>-8
So three value of this infinite set are -7, -6, -5 :P
3.
x/6≥3 multiply both sides by 6
x≥18
So three value of this infinite set of solutions are 18,19,20
No solutions in real numbers. So <u>D.</u>
Answer:
The circumference of the CD is approximately 38 cm
Step-by-step explanation:
The circumference of the CD can be seen as the distance around the CD.
The word "circumference" is used to describe the perimeter of circular objects.
To find an approximate value of the circumference of the CD, we will use this formula.
Circumference = π × diameter
let us take π to be = 3.142
∴ circumference = 3.142 × 12 = 37.6991 cm
we can round this up to teh nearest tenth as 38cm
Answer:
#3: 81
Step-by-step explanation:
I haven't done this type of math in a while so I'm unsure about #1 and #2, but #3 is 81.
3^4 = 3 × 3 × 3 × 3
3^4 = 9 × 3 × 3
3^4 = 27 × 3
3^4 = 81
