Answer:
y = 
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 5 when x = 6
k = 
= 
y = x ← equation of variation
When x = 5, then
y = × 5 =
Answer:
9^7
Step-by-step explanation:
7*2=9
Answer:
8 hours
Step-by-step explanation:
Let's first find how many inches the candle would have burned in 1 hour.
6 in:12 hours
x: 1 hour
We can divide 12 by 12 to get 1. This means we need to divide 6 by 12 to get x
x=1/2 inches
1/2 inches:1 hour
4 inches: x hours
We divide 4 by 1/2 to get 8. 1/2*8=4. This means...
x=1 hour*8=8 hours
X² = 16
x = ±√16
x = <span>±4
</span>The roots of this equation are -4 and 4
<span>Сorrect answer is third from above</span>
I think it whether 90 or 180 is there multiple choices?
