The answers are A, C, D I hope this helps mark me brainliest ❤
The ages of each relative are 30, 10 and 80 years respectively.
Translating the word problem into an algebraic expression, we have;
......equation 1
.......equation 2
......equation 3
Substituting eqn 2 and 3 into eqn 1, we have;
Dan, D = 10 years
For James;
James, J = 30 years.
For Paul;
Paul, P = 80 years.
Therefore, the ages of each relative are 30, 10 and 80 years respectively.

Answer: Your answer is 60
Step-by-step explanation:
Answer:
The solution for the inequality is x>17
Step-by-step explanation:
Consider the provided inequality.
Subtract 4x to both the sides.
Add 8 to the both sides.
Divide both the sides by 2.
Hence, the solution for the inequality is x>17
Hi.
Answer:
The answer should have positive sign but not negative.
Step-by-step explanation:
First, you add by 8 from both sides.
Then, simplify.
Next, you do is subtract by 4x from both sides.
Simplify.
Therefore, you divide by 2 from both sides.
Finally, you solve and simplify.
X=17 is the correct answer.
Hope this helps you!
Have a nice day! :)
Answer:
(1) equilateral triangle
Step-by-step explanation:
Firstly, we will find all angles of triangle BCD
we are given
m<C=60
m<A=35
m<ABD=25
we know that sum of all angles in any triangle is 180
so, we get
m<A +m<ABD+m<DBC+m<C=180
we can plug values
35+25+m<DBC+60=180
m<DBC=180-120
m<DBC=60
now, we can find other angle
m<DBC+m<C+m<CDB=180
now, we can plug values
60+60+m<CDB=180
m<CDB=180-120
m<CDB=60
So, we can see that
m<C=m<DBC=m<CDB=60
so, all angles are equal
so, triangle BCD is an equilateral triangle
