Step-by-step explanation:
When you have absolute value, you basically remove the negative symbol.
27-18=9 (difference between)
9/18=0.5 (9 as a percentage of original as a decimal)
0.5x100=50 (as a percentage)
50% increase
Answer:
The equation is 
Step-by-step explanation:
Arithmetic sequence:
In an arithmetic sequence, the difference between consecutive terms, called common difference, is always the same.
The general equation for an arithmetic sequence is:
Taking the mth term as reference, the equation can be written as:
t(4) = 8 and t(10) = 32
The common difference can be found:
So
Finding the first term:
So
So
The equation is
Answer:
Betty has 5 shoes, Helen has 15 shoes, and Natalie has 45 shoes.
Step-by-step explanation:
we can first try to solve this by assigning the sisters different number of shoes. lets give betty 0 shoes, Helen 10 shoes, and Natalie 30 shoes. this does follow the equation, however it does not equal 65.
what if we gave betty 5 shoes, Helen 15 shoes, and Natalie 45 shoes. This does follow the equation, because Helen has 10 more shoes than betty, and Natalie has 3 times more shoes than Helen. 5+15+45=65, So we have our answer!
9% of $30 is $2.70. 9% of $25 is $2.25. Therefore, Mira pays $32.70 and Gus pays $27.25. 32.70-27.25=5.45. The difference in the amount of that Mira and Gus paid is $5.45.
