Standard form for linear equations is Ax+By=C
10y-3x=5
-3x+10y=5....But "A" can't be negative ( or a fraction) so multiply each by -1
-1(-3x+10y=5)
Answer= 3x-10y=-5
If you would like to solve the equation v = 3k/t for k, you can do this using the following steps:
v = 3k/t /*t
v * t = 3k /3
k = v * t / 3
k = vt/3
The correct result would be k = vt/3.
Answer: 9 gallons
Step-by-step explanation:
Given: Ratio of colors in painting:
4 parts blue, 3 parts red, and 3 parts green.
Total parts = 4+3+3 =10
Fraction of blue =
Since, Quantity of blue color used = 12 gallons
Let total quantity of color be x,
Total color used = 30 gallons
Color used for green part only =
Hence, 9 gallons of paint were needed for the green part of the painting.
Answer:
only -7
Step-by-step explanation:
Just plug them in.
so for x=-7 So this one is extraneous
Then if you plug -3 in you get 1 = 1 so this one is not extraneous. if you need me to work this one out let me know.
