Answer:
Equation:
when n = 4
Step-by-step explanation:
Given
Direct Variation: P ∝ n
When n = 15, P = 150
Required
Determine the equation
Her earnings if she sold 4 necklaces
P ∝ n
Convert variation to equation
When P = 150, n = 15 (Substitute these values in the given equation)
Divide both sides by 15
Substitute k = 10 in
------- Equation that relates P and n
When she sold 4 necklaces, n = 4
Substitute n = 4 in the formula above
First, you would find out how much 1 gallon of gas would cost
You would calculate $19.46 divided by 14 gallons
Your quotient is $1.39
Then, you would divide how much money you actually have ( $8.70 ) by how much 1 gallon is ( $1.39 )
You get 6.25...
But since you cannot by 1/4 a gallon, you would round your quotient down to 6
Solution : 6 gallons

Answer:
-23/18
Step-by-step explanation:
-7/9 = -70/90
-5/10 = -45/90
-70-45 = -115
-115/90
-23/18
EDIT: whoops, I subtracted 45 from 70 instead of adding them. it should be correct now.
hope this helps, goodluck with your schoolwork/homework.
sorry for any errors or bad explanations.
For this problem, you have to look at the two triangles as equal, proven by the side angle angle proof. So, that means the top corner of the triangle JKM is equivalent to LKM. Meaning that m< JKM is also 38 degrees
