Answer:
7×0.5= 3.5 cups of water
Step-by-step explanation:
7×0.5 is the expression used to find how many cups she drank in a week
Answer: Hi!
First, we will use inverse operations to remove the 7. Subtract 7 on both sides:
7 - 7 = 0
4 - 7 = -3
Our equation now looks like this:
-11b = -3
Now we will use inverse operations to isolate the b. Divide -11 on both sides:
-11b ÷ -11 = b
-3 ÷ -11 = 3/11
Our equation now looks like this:
3/11 = b
3/11 is equal to b. This is your answer!
Hope this helps!

15 + 2(2 * 4) - 4^2
= 15 + 2(8) - 4^2
= 15 + 16 - 4^2
= 31 - 4^2
= 31 - 4 * 4
= 31 - 16
= 15
Therefore, your answer is: 15
Good luck on your assignment & enjoy your day!
