Answer:
34 years
Step-by-step explanation:
f = s + 28 Eq. 1
f+8 = 3(s+8) Eq. 2
f = father age
s = son age
replacing Eq. 1 on Eq. 2
(s+28) + 8 = 3(s+8)
s + 36 = 3*s + 3*8
s + 36 = 3s + 24
36 - 24 = 3s - s
12 = 2s
12/2 = s
s = 6
from the Eq. 1
f = 6 + 28
f = 34
Check
from the Eq. 2
34+8 = 3(6+8)
42 = 3*14
If you're saying their combined weight is 854, probably about 427kg each. 854Kilograms =854 kilograms... or, anything between 853.5-853.9
Answer:
its (0, 0) because the line goes through thex and y intercept
I assume what you want ti find is the value of m?
You try to have an quation of the form "m=" where on the one side there is nothing but m.
so first, let's get rid of the bracket:
-2(4-m)=10
-8+2m=10
now, let's add 8 to both sides:
-8+8+2m=10+8
2m=18
and divide by 2:
m=9
and that's our solution
