Answer:
x=-6
Step-by-step explanation:
There are 30 students in the classroom; 40% are men and 60% are women. How many men and women are in the classroom?
40/100 = 2/5 60/100 = 3/5 30 ÷ 5 = 6 3 × 6 = 18 so 18 are women 2 × 6 = 12
so there are 12 men.
.0091 rounded to the nearest hundredths is .01.
1.2×10‐2
Integer is a number which is not a fraction and is whole number. Yes whole numbers are 0,1,2 and so on but integer can also be negative such as -1,-2 etc.
-3⁰= -1 which is integer
18/3(is a fraction but when solved)=6 which is integer
root under49 is 7 which is integer.
some numbers which are not integer
1.2,-3.6,1/2 etc.
X^2 + 6x +9
(x+3) (x+3)
x+3 = 0
x = -3
answer: x=-3
