(x+15)+(x-13)=180
2x+2=180
2x=178
x=89
∠B=x-13=89-13=76°
Hope my answer helped u :)
Wouldn’t it be -3? i’m not sure tho but if y=2x-3 and the circle is (x-3)+(y+1) they both have (-3)
Answer:
Daniel is 21 years old
Step-by-step explanation:
Let
R ---> Rick's age
M ---> Mike's age
L ---> Larry's age
E ---> Ed's age
D ---> Daniel's age
we know that
The sum of their ages is 271
so
----> equation 1
Rick is 5 times the age of Mike
so
----> equation 2
Mike is half the age of Larry
so
----> equation 3
----> equation 4
----> equation 5
substitute equation 2, equation 3, equation 4 and equation 5 in equation 1
simplify
-----> equation 6
substitute equation 2 and equation 3 in equation 6
solve for M
Find the value of R (equation 2)
Find the value of D (equation 5)
therefore
Daniel is 21 years old
