Answer:
k = 7
Step-by-step explanation:
given y varies jointly with x and w then the equation relating them is
y = kxw ← k is the constant of variation
to find k use the condition when y = - 42, x = 2 and w = - 3 , then
- 42 = k × 2 × - 3
- 42 = - 6k ( divide both sides by - 6 )
7 = k
constant of variation is k = 7

b
Answer:
n=−5
Step-by-step explanation:
0.6(10n+25)=10+5n
Step 1: Simplify both sides of the equation.
0.6(10n+25)=10+5n
(0.6)(10n)+(0.6)(25)=10+5n(Distribute)
6n+15=10+5n
6n+15=5n+10
Step 2: Subtract 5n from both sides.
6n+15−5n=5n+10−5n
n+15=10
Step 3: Subtract 15 from both sides.
n+15−15=10−15
n=−5
