Since we know the length of one side, and it's a square, we simply multiply 10 by 10 to get 100. The final answer is 100 square feet.
Sleeping bag weights 8 pounds
sb=8
backpack+sleeping bag=31
b+sb=31
sb=8
b+8=31
subtract 8 from both sides
b+8-8=31-8
b+0=23
b=23
backpack weighs 23 pounds with out sleeping bag
equation is b+s=31
s=8
Answer:
-7/ 48
Step-by-step explanation:
Given that:
Average change in water level per 3 years = - 7/16
This means the water level decreases by - 7/16 on average every 3 years
The change in water level after a year will be ;
-7/16 = 3
x = 1
Cross multiply ;
3x = - 7/16
Divide both sides by 3
x = -7/16 ÷ 3
x = - 7/16 * 1/3
x = - 7 / 48
Hence, water level will change by - 7/48 after a year.
