Answer:
4343
Step-by-step explanation:
To find multiple of 7 from 1 to 100,
Take the quotient of 100/7=14
n=100 (number of terms)
n=100-14 (Without Multiple of 7=number of terms - multiple of 7)
=>n=86
Sum of 1 to 100 => Sn = n/2(a + an)
=> Sn = 86/2(1+100)
=> Sn = 43(101)
=> Sn = 4343

Step-by-step explanation:
Answer:
y = 4x
Step-by-step explanation:
Since there are going to be four quizzes a month (x), we know that we will multiply the number of months (x) by the number of quizzes (4). However, because we don't know how many months there are, we can define the months as (x), and instead put the total (y) is equal to the number of quizzes per month (4), multiplied by the number of months (x). Out final result is
(y = 4x)
Let
x---------> my favorite number
we know that
(x+9)/15=3/5------> 5*(x+9)=15*3-----> divide by 5 both sides----> (x+9)=3*3
x+9=9------> x=0
therefore
the answer is
My favorite number is 0
The answer will be 625j^4 k^4
