Answer:
9 to 44 is the ratio of the number of phone calls that we're from Plano to the total number of phone calls that day
Step-by-step explanation:
Given:
The total number of phone calls that was answered by secretary in a day = 88
The number of calls that were from Plano Texas = 18
To Find :
The of the number of phone calls that we're from Plano to the total number of phone calls that day
Solution:
The ratio of phone calls that we're from Plano to the total number of phone calls that day =
Now lets substitute the given value,
The ratio of phone calls that we're from Plano to the total number of phone calls that day =
Now reducing the fraction
=>
So the ratio is 9:44
Just subtract the top from the other equation like the 3rd one 9/3-1/6=8/3 <span />
X + y = 3,500 . . . (1)
x – y = 2,342 . . . (2)
(1) - (2) => 2y = 1158
y = 1158/2 = 579
x = 3500 - 579 = 2921
Therefore, he had 2,921 contempolary titles and 579 classic titles.
Let Alex's age is x and June's age is y y - x = 7 .........(1)
(x+5) + (y+5) =31
x + y = 21 .........(2)
by adding 1 and 2
2y = 28
y = 14
x = 7
