Answer:
75 and 45
Step-by-step explanation:
woman's age= w
son's age= s
--------------
- w=s+30
- w-15=(s-15)*2 ⇒ w-15=2s-30 ⇒ w=2s- 15
comparing the two above:
- s+30=2s-15 ⇒ s= 45 ⇒ w= 75
Answer:
9
Step-by-step explanation:
Hey There!
If you didnt know the given angles in the triangle added together equal the missing triangles supplement aka z+50
So all we have to do is set up an equation
z+50=30+6x-45
step 1 combine like terms
30-45=-15
now we have
z+30=6x-15
step 2 add 15 to each side
-15+15 cancels out
30=15=45
now we have
z+45=6z
step 3 subtract z from each side
z-z cancels out
6z-z=5z
now we have
45=5z
step 4 divide each side by 5
5/5 cancels out
45/5=9
z=5
so we can conclude that z=9
hope this helps :)
