Step-by-step explanation:
As corresponding sides of similar triangles are proportional,
Answer:
Equations:
a + b = 19
a = b + 2
a = Money that spent Laura
b = Money that spent Laureen
then:
(b+2) + b = 19
2b + 2 = 19
2b = 19-2
2b = 17
b = 17/2
b = 8.5
a = b + 2
a = 8.5 + 2
a = 10.5
Check:
10.5 + 8.5 = 19
24.12 because you have to divide 34 into 820 and then you get 24.12
The statement is a conditional statement.
