Answer:
![6 \frac{1}{14}](https://tex.z-dn.net/?f=6%20%5Cfrac%7B1%7D%7B14%7D)
Step-by-step explanation:
Write down the problem;
![2 \frac{4}{7} + 3 \frac{2}{4}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B4%7D%7B7%7D%20%2B%203%20%5Cfrac%7B2%7D%7B4%7D)
Simplify
![2 \frac{4}{7} + 3 \frac{1}{2}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B4%7D%7B7%7D%20%2B%203%20%5Cfrac%7B1%7D%7B2%7D)
Convert so that the fractions have a common denominator; multiply the numerator and denominator of both fractions such that the denominators are equal;
![2 \frac{8}{14} + 3 \frac{7}{14}](https://tex.z-dn.net/?f=2%20%5Cfrac%7B8%7D%7B14%7D%20%2B%203%20%5Cfrac%7B7%7D%7B14%7D)
Add the fractions;
![5 \frac{15}{14}](https://tex.z-dn.net/?f=5%20%5Cfrac%7B15%7D%7B14%7D)
Convert to mixed number;
![6 \frac{1}{14}](https://tex.z-dn.net/?f=6%20%5Cfrac%7B1%7D%7B14%7D)
-4(-5-b)=1/3(b+16) Multiply both sides by 3 to get rid of the fraction
-12(-5-b)=b+16 distribute the -12 to get rid of the parenthesis
60+12b=b+16 get the b on the left side and non b values to the right side
11b=-44 solve for b
b=-44/11 simplify the fraction
b=-4
3/5(t+18)=-3(2-t) multiply both sides by 5/3 to get rid of thefraction
t+18=-5(2-t) distribute the -5 to get rid of the parenthises
t+18=-10+5t get the t to the left side and non t values to the right
-4t=-28 solve for t
t=7
Answer:
n = 5
Step-by-step explanation:
Given
n + 16 = 21 ( isolate n by subtracting 16 from both sides )
n = 5
Answer:
Option A - $ 40.00 - $9.50 - $4.25 - $5.00
Step-by-step explanation:
Given : Tu went to the movies. he bought 2 tickets for $ 9.50 each, popcorn for $ 5.00, and 2 drinks for $ 4.25 each. He give the clerk two $ 20.00 bills.
To find : Which expression can not be used to find the amount of changes Tu got?
Solution :
He give the clerk two $ 20.00 bills i.e.
or 40
He bought 2 tickets for $ 9.50 each i.e.
or -9.50-9.50
Popcorn for $ 5.00 i.e. ![-5](https://tex.z-dn.net/?f=-5)
2 drinks for $ 4.25 each i.e.
or -4.35-4.25
The expression can not be used to find the amount of changes Tu got is
' $ 40.00 - $9.50 - $4.25 - $5.00'.
Therefore, option A is correct.
