Two people. tom and marcy have combined age of 115 years. the differences in their age is 5 years. what is the age of each person? slove using a system of equations where: x= toms age y= ? equations ? + ? =? ? +? =

Marcy is 55, Tom is 60

Step-by-step explanation:

x= toms age

y= Marcy's age

x+y = 115

x-y = 5

We will want to use elimination since we have a +y and a -y in the system of equations.  Add the equations together

x+y = 115

x-y = 5

2x = 120

Divide by 2

2x/2 = 120/2

x = 60

Tom is 60

We need to find marcy's age

x+y = 115

60+y = 115

Subtract 60 from each side

60-60 +y = 115-60

y = 55

Marcy is 55

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

yes
