Answer:
d represents distance
d = -16.8
Step-by-step explanation:
From the question, we are to find the vale of d from the expression
12+d = -4.8
Subtract 12 from both sides
12+d-12 = -4.8-12
d = -4.8-12
d = -16.8
Hence the value of d that makes two equation true is 16.8
d represents distance
Answer:
The age of triplets is 42 years old
Step-by-step explanation:
The question in English is
The sum of the ages of twins and triplets is 150 years if the ages are exchanged the new sum is 120 years. What is the age of triplets?
Let
x -----> twins age
y ----> triplets age
we know that
2x+3y=150 ------> equation A
2y+3x=120 -----> equation B
Solve the system by graphing
The intersection point both graphs is the solution of the system
The solution is the point (12,42)
see the attached figure
therefore
The age of triplets is 42 years old
