Hello :
<span>a reflection over the y-axis</span>
We're dividing fractions, so we will flip the one in the denominator upside down and we will multiply it with the numerator.
Let's equal this too 8/x
Cross multiply.
Divide both sides by 15.
Answer:
It was 4 years.
Step-by-step explanation:
To solve this problem we need to use the appropriate formula for simple interest, which is shown below:
M = C*r*t
Where M is the amount of interest, C is the initial amount of money, r is the rate of interest and t is the time elapsed in years. Applying the data from the problem we have:
840 =7000*0.03*t
840 = 210*t
210*t = 840
t = 840/210
t = 4
It was 4 years.
Alright, so the first step we are gonna do to solve this problem is subtract since Mason ate 5 ounces of the peanuts and so, we need to subtract 5 out of 29.8.
29.8 - 5 = 24.8
So, now there is 24.8 ounces.
Now we move onto the next step which is division. As you can see in the question it says "Then he divides the rest of the peanuts equally among 4 friends."
24. 8 ÷ 4 = 6.2
Since the answer is supposed to be a decimal..that's your answer!
So overall, each of Mason's friends get 6.2 ounces of peanuts.
Hope this helps!
