3(3w-4)=-20
9w-12=-20
9w=-8
w= -8/9
-3x-4.6=5.9 (multiple all numbers by 10 to rid of decimals)
-30x-46=59
-30x=105
x= -3.5 or x= 7/2
Answer:
1) is 34
Step-by-step explanation:
On the internet............................
You will set the equation up as part/whole = percent/100 and when you replace it with your numbers you get 60/x = 80/100 now you cross multiply and do 60*100 = 80 * x and you get 6,000 = 80x now you divide both sides by 80 then you get 75 was the original price
Answer:
m = 11
Step-by-step explanation:
Since the points are collinear then the slope between points are equal.
Calculate the slope m using the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (5, 1) and (x₂, y₂ ) = (1, - 1)
m = = =
Repeat with
(x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (m, 4)
m = = =
Cross- multiply
m - 1 = 10 ( add 1 to both sides )
m = 11
