Answer:
1. 6.4 meters of streamers left to make pompoms
2. He will be able to make 8 pompoms
Step-by-step explanation:
1.
4 x 1.6 = 5.6 meters were used to make decorations.
Then we do 12 - 5.6 = 6.4
2.
per one pompom it takes 0.8 meters of streamers.
6.4 is the left over so we do
6.4 divided by 0.8 = 8 pompoms you can make
Answer:
-5 ≤ n ≤ 3
Step-by-step explanation:
Firstly we solve the equation two at a time;
5n + 17 ≥ n - 3
5n - n ≥ -3 - 17
4n ≥ -20
n ≥ -5
-5 ≤ n
n - 3 ≥ -15 + 5n
n - 5n ≥ -15 + 3
-4n ≥ -12
-n ≥ -3
n ≤ 3
Therefore,
5n+17 ≥ n–3 ≥ –15+5n, becomes
-5 ≤ n ≤ 3
Answer: 2
Step-by-step explanation:
This should be right because 5 * 2 = 10
5x mean that 5 * x = 10
Hope this makes sense
