Answer:
52
Step-by-step explanation:
these equations added together equal 180. so x+2x+24 = 180. add like terms (x+2x=3x) , subtract 24 from both sides, divide by 3 on both sides to get x by itself
Answer:
P = 8
Step-by-step explanation:
Given that P varies inversely with x then the equation relating them is
P =
← k is the constant of variation
To find k use the condition P = 7 when x = 8 , then
7 =
( multiply both sides by 8 )
56 = k
P =
← equation of variation
When x = 7 , then
P =
= 8
