B, because when you add 90+80 you get 170 and 170/2 = 85
If you would like to solve the inequation 4 * x - 4 - 3 * x > 13 - 7 * x - 1 + 8, you can do this using the following steps:
4 * x - 4 - 3 * x > 13 - 7 * x - 1 + 8
4 * x - 3 * x + 7 * x > 4 + 13 - 1 + 8
8 * x > 24 /8
x > 24/8
x > 3
The correct result would be x > 3.
Answer:
16 minutes per meter
Step-by-step explanation:
Depth = 3/8 meters
Time taken = 6 minutes
What is the unit rate in minutes per meter?
Time taken per depth = minutes per meter
Unit rate in minutes per meter = 6 minutes ÷ 3/8 meters
= 6 minutes × 8/3 meters
= 48/3
= 16 minutes per meter
Answer:
45
Step-by-step explanation:
5 times 5 is 25 plus 20 is 45 hope this helps
You do 3x6 first to get 18.
You get 3-18+2.
Then you do 3-18 which is -15.
You get -15+2.
Then you do -15+2 which is -13.
It equals -13.
