Answer:

-5n + 16

Step-by-step explanation:

Distribute the 7 to the equation inside the parenthesis.

7(n + 1) - 12n + 9

7n + 7 - 12n + 9

Bring the -12n towards the 7n.

7n - 12n + 7 + 9

Add or subtract like terms.

7n - 12n + 7 + 9

  -5n     +   16  

Answer:

-5n + 16

Is the following conditional true? If p<2, then p≤2.
Romashka-Z-Leto [24]
If this is the only information you are given then no. This is because the < sign means that p is less than 2. The second sign cannot be true if the first one is because the second sign says that p is less than or equal to 2.

Mexine can stack 20 boxes in 15 minutes. how long will it take her to stack 100 boxes
Charra [1.4K]
Lets use a rule of three simple with direct proportion to solve:
 20 boxes -----> 15 min
100 boxes ----> x
x = (100)(15)/20
x = 75
therefore it takes 75 mins to stack 100 boxes

If we use fractions to solve:
15/20 = x/100
and solve for x.
20/15 = 100/y
solve for y
