B.) S<span>ubstances that are made up of only one type of atom</span>
The second one 3(x-9)=40
3x-27= 40 (distributive property)
3x= 40+27
X= 67/3
X= 22.3
Answer:
x = 3
Step-by-step explanation:
since they are similar use these ratios
x/9 = 1/3
do cross multiplication
9*1 = 3*x
9/3 = x
3 = x
Answer:
the correct answer is 17.5%
Step-by-step explanation:
Answer:
n ≥ -1 or n ≤ 3
Combined:
-1 ≤ n ≤ 3
Since the inequalities are ≤, it'll be a closed circle
The closed circle will start AT -1 and another closed circle will end at 3
