The sum is
Step-by-step explanation:
First term(a) = 1
Common difference(d)=2-1=1
No.of term(n)=50
Sn=n÷2(n+1)=50÷2(50+1)=1275
Answer:
Step-by-step explanation:
The first step is to make the division of the fractions and
. To do this, you can flip the fraction over and multiply the numerators and the denominators of the fractions. Then:
Reduce the fraction :
Now you can make the subtraction: in this case the Least Common Denominator (LCD) will be the multiplication of the denominators. Divide each denominator by the LCD and multiply this quotient by the corresponding numerator and then subtract the products. Therefore you get:
A.
Subtract the cost of the boots from the total cost. Divide that answer by 4.
B.
Add the cost of the sandals and the cost of the boots. Divide the sum by 4.
C.
Multiply the total cost by 4. Subtract the cost of the boots.
D.
Divide the total cost by 4. Add the cost of the boots.
