8*(n+6)=80
distribute
8n+48 = 80
subtract 48 from each side
8n = 32
divide by 8
n=4
Answer:
you would just 4.8 x how many years
Step-by-step explanation:
Answer: 1.2 m
Step-by-step explanation:
Given
The length of the ramp to the building is 3.7 m
Distance from the beginning of the ramp to the base of the building is 3.5 m.
Suppose h is the height of the ramp
from the figure, we can write

So, the height of the ramp is 1.2 m
4cms would be 0.04 meters.
Answer:
5 ≤ x ≤ 50; Billy needs to make at least 5 more pizzas but no more than 50
Step-by-step explanation:
Let
x -----> the number of pizzas
we have the compound inequality

Divide the compound inequality into two inequalities
----> inequality A
The solution of the inequality A is the interval -----> (-∞,50]
-----> inequality B

Rewrite

The solution of the inequality B is the interval -----> [5,∞)
therefore
The solution of the compound inequality is
(-∞,50] ∩ [5,∞)=[5,50]
so

Billy needs to make at least 5 more pizzas but no more than 50
