so we're trying to figure what portion of silas' slime is detergent. we know that his slime is a combo of 5 oz glue and 2 oz detergent for a total of 7 oz of slime.
what we want to find is how much of those 7 oz of slime is detergent.
quite simply 2 oz of the 7 is detergent.
to make that into a percent just divide 2 by 7.
2/7 = 0.2857
then move the decimal over two spots to get
28.57 or
D. 28.6%
just remember that percents are just how much makes up the whole.
38.97 would be standard form
Answer:/?idk
Step-by-step explanation:
Answer: a) y=-29x-20 b) y=3/5x-18
Step-by-step explanation:
a) m = (-49-38)/(1 - (-2)) = -87/3 = -29
y=-29x+b --> Substitute (1,-49) as a point
(-49)=-29(1)+b
-49=-29+b
-b=-29+49
b=-20
Therefore, the equation of the line is y=-29x-20
b) m = (-18-(-9)/(0-15)) = -9/-15 = 3/5
The y-intercept is (0,-18) as it's where the line intersects the y-axis and x equals 0
Therefore, the equation of the line is y=3/5x-18
