!5% is equivalent to 15 parts over the whole 100 part. It is written in proportions as 15/100.
Similarly, you need to find how many parts in 80 are equivalent to 15%or 15/100. So, just equate both equation with x as an unknown.
x/80 = 15/100
x = (15/100)*80
x = 12
Thus, the 15% of 80 is 12.
Answer:
1/5(14+×)
Step-by-step explanation:
The sum of 14 and x has to be (14+x)
X=6y
sum of their reciprocals
(1/x)+(1/y)=7
x=6y
1/6y+1/y=7
1/6y+6/6y=7
7/6y=7
times both sides by 6y
7=42y
divide both sides by 42
1/6=y
x=6y
x=6(1/6)
x=6/6
x=1
the numbers are 1 and 1/6
Answer:
p=4
Step-by-step explanation:
4p-3=13
4p=3+13
4p=16
p=4
Find a common denominator...
1/5 = 7/35
7/35 = 7/35
6/25 = ... can't have 35 as a denominator. Not equivalent.
