Answer:
x = 4
Step-by-step explanation:
as it is parallelogram opposite sides are equal
so14x -7= 10x-9
14x-7+9=10x
14x -16 = 10x
14x -10x = 16
4x =16
x = 16/4
x = 4
also u can put x = 4 in both expressions and u will get answer of both 49
So k=katie's' age
m=mara's age
k is 2 times as old as m
k=2m
sum is 24
add means sum
k+m=24
so we have
k+m=24 and
k=2m
subsitute
2m+m=24
add
3m=24
divide both sides by 3
m=8
subsitute again
k=2m
k=2(8)
k=16
katie=16
mara=8
Answer:
