To find the line, you need to use the point-slope formula because you're given both the slope and a point.
y - y₁ = m(x - x₁)
m = -2/5
x₁ = 10
y₁ = 3
y - 3 = -2/5(x - 10)
y - 3 = -2/5x + 4
y = -2/5x + 1
y = -2/5x + 1 is the line.
So to get this the easiest way would be to:
-put 90,000,000 over 186,000 and cancel out zeroes so you have 90,000 divided by 186 ( so it makes more sense in long division later)
-Then divide 90,000 by 186
-get 483.87 seconds
Hope this helped!
All parts of arithmetic equations have names. In an addition equation, addends are the numbers that are added together to give a sum. In a subtraction equation, the subtrahend is taken away from the minuend to give a difference. In a multiplication equation, factors are multiplied to give a product.
So from the looks of it i would say c ( really sorry if i am wrong)
HI THERE!
i can help you :)
------------------------------------------------------------------------------------------------------------------
let the number of raisins (in pounds) be R and the number of peanuts (in pounds be p.
since the bag is 30 pounds, so R+P =30
the total cost of the bag is 30 pounds* 4.05 per pound = $121.50 .
now we can use the per-pound costs to write an equation . . .
5R+3.8P=121.5
Now just solve that first equation. . (R+P=30) for R. R= 30- P
now use that to substitute in the other equation
5R+3.8P=121.5
5(30-p) + 3.8P=121.5
solve for p
150- 5P+ 3.8p = 121.5
150-1.2p=121.5
150-1.2p=121.5
-1.2p=-28.5
P=23.75
now use that to find r
R+p =30
r+23.75=30
R=6.25
(hope this helps sorry it took so long to type )
have a good day !
