Answer:
x < -3
Step-by-step explanation:
2x - 3 < -9
Add 3 to each side
2x - 3+3 < -9+3
2x < -6
Divide by 2
2x/2 < -6/2
x < -3
the answer is each friend gets 2/3 cookie
The product of three and a number (3n) is 12 more than (=12 +) the sum of the number and 26 (n + 26). Put all of those together.
2n = 12 + n + 26 Combine like terms. (12 + 26)
2n = 28 + n Subtract to get the variables together. (2n - n)
n = 28
Answer:
A) P = 6n + 8
Step-by-step explanation:
Given:
Perimeter of the 1 triangle = 24
Perimeter of the 2 triangle = 30
Perimeter of the 3 triangle = 36
Let's check with option A.
P = 6n + 18, where "n" is the number in the figure.
Plug in n = 1, we get
P = 6(1) + 18
= 6 +18
P = 25 True.
Plug in n =2, we get
P = 6(2) + 18
= 12 +18
P = 30 True.
Plug in n =3, we get
P = 6(3) + 18
P = 18 + 18
P = 36, true.
Therefore, the answer is A. P = 6n + 18
