Answer:
13,88,22
On the first evening Jamie received 13 calls.
Step-by-step explanation:
Total number of phone calls received by Jamie over three evenings = 123
Let the number of phone calls received on the third evening = x.
The number of phone calls received on the second evening = 4*x.
The number of phone calls received on the first evening = [tex]x-9[/tex]
Expressing in equation form:
[tex]\[x+4x+x-9=123\][/tex]
[tex]\[=>6x-9=123\][/tex]
[tex]\[=>6x=132\][/tex]
[tex]\[=>x=\frac{132}{6}\][/tex]
[tex]\[=>x=22\][/tex]
So Jamie received 22 calls on the third evening, 88 calls on the second evening and 13 calls on the third evening.
