C
Step-by-step explanation:
Answer:
3x+0.3=3.3.
\ /
We move all terms to the left:
3x+0.3-(3.3.)=0
We add all the numbers together, and all the variables
3x+0.3-0=0
We add all the numbers together, and all the variables
3x+0.3=0
We move all terms containing x to the left, all other terms to the right
3x=-0.3
x=-0.3/3
x=-0.3/3

Answer:
The sides are 5,18,16
Step-by-step explanation:
To find the perimeter of a triangle, we add up all the sides
n +4n-2 + 5n-9 = 39
Combine like terms
10n -11 = 39
Add 11 to each side
10n-11+11 = 39+11
10n = 50
Divide by 10
10n/10 =50/10
n = 5
Now we need to find each side
n = 5
4n-2 = 4(5)-2 = 20-2 =18
5n-9 = 5(5) - =25-9 = 16
The sides are 5,18,16
Answer:
C
Step-by-step explanation:
Associative property states that when three or more numbers are added, the sum is the same regardless of the grouping.
This means that (4x + 13) + 11 is the same as C. 4x + (13 + 11)
