Pam is 3 years older than her sister, jan. the sum of their ages is 99. find their ages.

Pam is 51.

Jan is 48.

Step-by-step explanation:

Pam is 3 years older than Jan so her age is x + 3 where x is Jan's age. When we add Pam's age and Jan's age, the sum equals 99.

So x + x+3 = 99. Solve for x.

2x+3 = 99

2x=96

x= 48

So Jan is 48 years old. This means Pam is 51.

pam is 51 and jan is 48

Step-by-step explanation:

pam is x and jan is y

(x + 3) + y = 99

- 3 on both sides

x + y = 96

divide 96 by two

96/2 is 48

add 3 to 48 (pam’s age)

pam is 51 and jan is 48

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

answer: it's a
