Answer:
x = 7
Step-by-step explanation:
all we know is that she had 1 brownie at the end, in the end she gave half her brownie to tyler, so add one who will get 1 1/2, before that she split her brownies between her friends, so multiply 1 1/2 by 2 and you will get 3, before that she gave 1/2 a brownie to Kiran, so we would add 1/2 to 3 and get 3 1/2, before that she first split it in half for a her friends, so at last, multiply 3 1/2 by 2 and you will geet 7 as your final answer.
The answer would be 7!
You would take 1 and add 1/2 to it
= 1 1/2
Then, multiply by 2
= 3
Then add 1/2 to that
= 3 1/2
Then multiply 2 one more time
= 7
This is because Mai gave half of her brownie and then half more of her brownie to each person she gave it to
So you would add 1 + 1/2 and then multiply by 2
Since she did this to 2 people you would repeat one more time!
Hope this helped!

What has to happen for scales to be balanced?
Answer:
When the pans contain exactly the same mass the beam is in balance. ... You can place an object in one pan and standard weights in the other to find what the object weighs. Here balance scales are used to show that the box "x" has a mass of 4
Answer:
a balances measure mass, while scales measure weight. So if you bring a balance and a scale to the moon, the balance will accurately give you the mass of, say, a moon rock, whereas the scale will be affected by the gravity. A balance determines mass by balancing an unknown mass against a known mass.

I think it is 72%
Step-by-step explanation:
Answer:
A. 12%
Step-by-step explanation:
I counted the number of dots in all, and the number of dots in the columns 7 - 8.
There are 25 dots in allThere are 3 dots in columns 7 - 8.This means that 3/25 of the students in the class have 7 - 8 people in their houses.
Now let's convert the fraction into a decimal, which we'll then convert into a percent.
Let's multiply the numerator and denominator of 3/25 by 4.
We get 12/100!
12/100 as a decimal is 0.12
0.12 as a percent is 12%
Is there a letter which has 12% as an option? Yes, there is! It's A.
The answer is A. 12%

Hockey teams are often confronted with the dilemma of whether or not to pull a goalie at the end of the game when they are down a goal or two. One analyst reports that in 40% of those games in which a goalie was pulled a goal was scored with one empty net, and of those goals scored 25% were scored by the team that pulled the goaltender. Given that the goalie has been pulled by a team, what is the probability that team will score a goal?
Answer:
Step-by-step explanation:
so 30% of the total number of goals shot is 5
30% of what number is 5....turn ur percent to a decimal..." of " is multiply
let the number of shots represent x
0.30x = 5...divide borh sides by 0.30
x = 5/0.30
x = 16.66 shots
